Why computer can’t connect to Wi-Fi Hotspot on Android phone for a long time (SOLVED)

Posted by Alex On June 12, 2022

Why my computer cannot connect to the Android mobile Wi-Fi hotspot for a long time

After updating Android, I ran into a problem that the computer sees a mobile hotspot, but at the same time:

1. It does not try to connect to it automatically

2. When I select the Access Point manually, an attempt is made to connect, which ends in failure after about a minute

See also:

Additional symptoms of the problem:

3. Before the Android update on the phone, connecting to the Hotspot was fast and without problems

4. The computer can sometimes connect to the mobile hotspot

5. New devices quickly connect to Hotspot on Android without problems

One reason for this behavior could be a new setting that allows you to use an arbitrary MAC address for the mobile hotspot.

How to set permanent or random MAC address for Hotspot on Android

Go to Settings → Connections → Mobile Hotspot and Tethering → Mobile Hotspot.

Click the “Configure” button.

Click the “Advanced” button.

Look for “MAC address type”.

There are two options to choose from:

  • Randomized MAC
  • Phone MAC

If you select the first option (“Randomized MAC”), a random MAC address will be generated for the created Mobile Access Point. If you select the second option (“Phone MAC”), the permanent MAC address of the phone will be used for the created mobile hotspot.

Select “Phone MAC”, save the settings and check if this solves the problem with the slow connection to the Hotspot on Android.

What is the “Randomized MAC” setting for? Is it safe to turn it off

The question may arise, why is the “Randomized MAC” setting enabled by default, which creates serious problems when connecting to a mobile hotspot? Perhaps it is very important and should not be disabled?

The MAC address of each device must be unique. More precisely, each network interface (one device, including a phone, can have several network interfaces) must have a unique MAC address. This MAC address allows you to distinguish one device from another. You can also find out the manufacturer of the device by the MAC address (for example, Samsung, Apple, and so on).

See also:

Enabling the “Randomized MAC address” setting makes it so that for a hypothetical third-party observer, an Access Point is created each time on a device unfamiliar to him.

But you need to remember that each Access Point has the following identifiers:

  1. Device MAC address (BSSID)
  2. Access Point Name (ESSID)

That is, if you are really concerned about privacy issues, then in addition to enabling the “Randomized MAC” setting, you also need to change the network name every time, otherwise the “Randomized MAC” setting loses all meaning.

In fact, most users just do not need to enable the “Randomized MAC” setting. Enabling the “Randomized MAC” setting without taking other measures (for example, changing the network name each time the AP is created) does not make much sense. But at the same time, other devices that, when connected to the AP, can be guided by its MAC address, begin to experience connection problems.

In short, if you do not have a clear understanding of what exactly you need the “Randomized MAC” setting for and/or you do not take other steps to make it difficult for your phone to be identified as an AP and at the same time you are experiencing problems connecting to a mobile AP, then you can safely disable this setting.

If your devices connect to the mobile AP without problems with the “Randomized MAC” setting enabled, you can leave it enabled.

Do I need to enable the setting “Support Wi-Fi 6 standard”

If after changing the MAC address type setting, your computer or other devices continue to experience problems connecting to the Mobile Hotspot, then pay attention to the following two settings.

The first setting is “Support Wi-Fi 6 standard”. This item is located in: Settings → Connections → Mobile Hotspot and Tethering → Mobile Hotspot → Configure → Advanced → Support Wi-Fi 6 standard.

“Support Wi-Fi 6 standard” brings many technical improvements and data transfer speeds. But that's in theory. If, in practice, your devices cannot connect to the Access Point with the “Support Wi-Fi 6 standard” setting enabled, then disable it.

Choose “2.4 GHz” or “5 GHz”?

In theory, Wi-Fi at 5 GHz is faster. This is due both to the technical characteristics of the 5 GHz channels and to the fact that these channels are currently less crowded. However, in practice, the transmission area of a 5 GHz Wi-Fi signal is less than 2.4 GHz. Some older devices do not support 5 GHz operation. Some devices, even those that support 5 GHz, are slower to find the Access Point at these frequencies.

Although it is recommended to select the 5 GHz band in the Access Point settings, if you are not satisfied with the quality of the mobile Access Point, you can change the Frequency Band of your Access Point. To do this, go to: Settings → Connections → Mobile Hotspot and Tethering → Mobile Hotspot → Configure → Band. There you will be presented with a choice of:

  • 2.4 GHz
  • 5 GHz preferred

Switch to “2.4 GHz” and see if that solves your problem.

Internet via Bluetooth in Linux: how to set up and why the speed is slow

Posted by Alex On February 22, 2022

In this tutorial, you will learn how to set up an Internet connection via Bluetooth in Linux, as well as why the Internet speed via Bluetooth is slow.

How to connect my computer to the Internet through my phone via Bluetooth

Internet via Bluetooth is one of the options for using a mobile phone to access the Internet from a computer. Looking ahead, we note that this is not the best option because:

1) the connection speed will be quite slow,

2) the setup, although generally simple, is slightly more complicated than other connection options

As alternative methods for accessing the Internet from a computer via a mobile phone, the following are recommended:

If your computer does not have Wi-Fi and you do not have a USB data cable for connecting your phone by wire, then the method described in this article is suitable for you – accessing the Internet via the mobile phone's Bluetooth tethering.

The connection algorithm is as follows:

  1. Pairing your phone and computer via Bluetooth
  2. Turning on the Bluetooth tethering on the phone
  3. Setting up a computer, which consists in connecting to the phone's Bluetooth tethering (selecting Bluetooth as the Access point)

So, let's look at how to connect a computer to the Internet through Bluetooth and your mobile phone in Linux.

Checking and starting the Bluetooth service

Connecting a mobile phone to a computer via Bluetooth is called pairing.

Check if the Bluetooth service is running on your computer – to do this, connect your Bluetooth device (if it is disconnected) and look for the Bluetooth icon next to the clock:

The Bluetooth service status can be checked on the command line: 

systemctl status bluetooth

If the status of the service is other than “active (running)” and you do not see the Bluetooth tray icon, then you need to execute the following commands from this section. If the service is running, skip the following commands and skip directly to the next section to pair your phone with your computer.

Install required packages in Debian, Linux Mint, Ubuntu, Kali Linux and their derivatives: 

sudo apt install bluez blueman

Install required packages in Arch Linux, Manjaro, BlackArch and their derivatives: 

sudo pacman -S bluez bluez-utils pulseaudio-bluetooth blueman

The following commands are the same for all distributions.

Start bluetooth service: 

sudo systemctl start bluetooth

Adding it to startup: 

sudo systemctl enable bluetooth

Connecting a mobile phone to a computer via Bluetooth (phone pairing)

Turn on Bluetooth on your mobile phone.

Both a mobile phone and a computer can initiate pairing.

On your mobile phone or computer, search for Bluetooth devices.

If the devices do not see each other, then start searching for devices at the same time on the computer and mobile phone.

When the desired device is found, click on it to start pairing.

A prompt will appear on your mobile phone to establish pairing – agree to this proposal.

   

After that, on the computer it will be proposed to pair with the phone – agree (“Confirm”). If you are prompted to connect by someone else's device, then reject the request (“Deny”).

Immediately after pairing, or at the next connection, an authentication request will be made – the options are “Always accept” and “Accept”. The “Deny” button means rejecting the request.

After pairing, and also if you have selected the “Always accept authentication” option, the devices will connect to each other automatically as soon as Bluetooth is enabled on them.

Turning on the Bluetooth tethering

Go to the settings of your phone, this can be done by unrolling the curtain from top to bottom and clicking the gear icon.

Further, the name of the settings items may differ on different phone models, but the essence will be the same everywhere.

Go to the “Connections” section.

Find the item “Mobile Hotspot and Tethering” there.

Turn on “Bluetooth tethering”.

   

Connect to a Bluetooth tethering on a computer

Your computer's network settings should now show an option for Bluetooth, Mobile broadband, or similar.

Activate this connection so that the computer starts using the Internet via Bluetooth.

You can turn on the Bluetooth connection directly on the computer, bypassing the steps to turn on the Bluetooth tethering on the phone as shown above – in this case, the phone will prompt you to Allow Bluetooth tethering.

Why is the Internet speed slow over Bluetooth

When successfully connecting to the Internet via Bluetooth, the first thing you may notice is the speed of the connection. On the most modern Bluetooth 5.* protocols, it is up to 1.4 megabits per second (2 megabits per second at the moment). As you can see from the screenshot, the speedtest.net Internet connection speed test showed a speed of 1.66 megabits per second.

This is 210-220 kilobytes per second, if these units are more familiar to you. This is very slow, and on Bluetooth versions 4.* the speed is only 800 kilobits per second, that is, 2 times slower.

Thus, if the speed of the Internet via Bluetooth is too slow for you, all you can do to increase the speed of the Internet via Bluetooth is to switch to the Bluetooth 5.* protocol (both devices – the phone and the computer – must support this protocol). If this speed is not enough for you, then use Wi-Fi or data transfer via USB:

How to use an Android phone to access the Internet on a computer without Wi-Fi in Linux

Posted by Alex On February 22, 2022

In the article “How to share mobile Internet with other phones and computers”, we already talked about how to use a mobile phone as an Access Point, but what if the computer does not have a Wi-Fi adapter or drivers are not installed for it?

This article is devoted to the answer to this question – it tells how to connect a computer to the mobile Internet using a USB cable.

In fact, this method is even simpler than creating a mobile hotspot.

How to Use Android Phone as USB Tethering in Linux

As you can see in the screenshot, the computer does not have an Internet connection.

Start by connecting your phone to your computer with a USB cable.

Then go to the settings of your phone, this can be done by unrolling the curtain from top to bottom and clicking the gear icon.

Further, the name of the settings items may differ on different phone models, but the essence will be the same everywhere.

Go to the “Connections” section.

Find the item “Mobile Hotspot and Tethering” there.

Turn on “USB tethering”.

Everything is ready – now your computer is online and can connect to the Internet. You can install Wi-Fi drivers or perform other network actions that you need.

No additional configuration is required on the computer. Now the computer is connected to the network – the USB tethering connection has a wired connection icon.

What to do if the USB modem item is not active or missing

The USB modem item may be inactive in two cases:

  1. The phone is not connected to the computer with a USB cable.
  2. USB cable does not support data transfer

Try another USB cable – the one that came with the phone should support data transfer.

Things to remember when using a mobile phone for the Internet

  1. Please note that if the phone is not connected to Wi-Fi, then mobile data will be used – if you do not have an unlimited data plan, then this will cost you money.
  2. You can connect your phone to a Wi-Fi network and still use it as a USB modem. The result is that your computer is using Wi-Fi through your phone, and not mobile data.
  3. If, when you turn on the USB modem, there is still no Internet access on the computer, then check if other network connections are disabled: for example, via Wi-Fi or by wire, the computer can be connected to a router that does not have Internet (disabled for non-payment or damaged cable).
  4. If you disconnect the phone from the USB cable, and then connect it to the computer again, you will need to turn USB tethering on again in the phone each time
  5. While the mobile phone is operating as a USB modem, you cannot send and receive files from it

How to enable file transfer between computer and phone

When the USB modem is enabled, it is not possible to exchange files between the computer and the phone.

In order to make it possible to copy files, you can disconnect the phone from the computer, and then reconnect and, when asked for permission to transfer files, provide it.

Another option is to disable the USB modem and enable data transfer (or only charging) in the phone settings without disconnecting it from the USB cable. To do this, open the curtain and expand the notification “USB tethering turned on”.

Click to configure the USB connection to the corresponding label.

Instead of “USB tethering” select “USB tethering” or “Charging phone only”.

How to share mobile Internet for another phone via Wi-Fi and Bluetooth

Using Bluetooth, a mobile phone can share the Internet (share an Internet connection) with another phone or computer. The speed of Bluetooth is quite slow, so it is recommended to create a mobile Wi-Fi hotspot on your phone and distribute the Internet through it, see how to do this in the article “How to share mobile Internet with other phones and computers”.

If Wi-Fi for some reason does not suit you, then you can distribute the Internet via Bluetooth. Scenario example: An Internet donor phone is connected via Wi-Fi to an Access Point. You need to connect a second phone to the Internet, but you can't or don't want to do it over Wi-Fi. In this case, as a temporary connection, you can distribute the Internet via Bluetooth.

How to share the Internet via Bluetooth

Start by pairing phones via Bluetooth.

To do this, turn on Bluetooth on both phones and click the “Search” button.

To go to the Bluetooth settings, press and hold the Bluetooth icon that you previously used to turn on Bluetooth.

In the Available devices list, select the phone you want to pair with.

On both phones, tap “Pair”.

After that, on the phone that you want to connect via Bluetooth to the Internet, click the gear icon opposite the donor phone that will distribute the Internet.

In the window that opens, activate “Internet access”.

Then return to the donar phone – on the screen of which a request will appear to allow the Bluetooth tethering mode, click the “Allow” button.

If you get confused as to which phone has a Bluetooth tethering enabled and which one is using the Internet via Bluetooth, then the Bluetooth connection setting for the donor phone will say “Internet connection sharing”.

And on a phone that uses the Internet via Bluetooth, it will say “Internet access”.

How to share mobile Internet with other phones and computers

Posted by Alex On February 20, 2022

This guide will tell you how to turn on Wi-Fi on your phone for other devices so that they can use the Internet. This can come in handy, for example, when you want your friends to be able to connect to the Internet if they have a bad signal or use up their data limit. Another example: you can connect your laptop or computer to your phone via Wi-Fi and access the Internet through your phone, even if you are away from home or your “wired” ISP is out of service.

The specific names of menu items may vary depending on phone models – it's not a problem, the main thing is to understand the essence, then you can set up a mobile hotspot on any phone.

How mobile hotspot works

Your phone can use the Internet from:

  • mobile operator
  • WiFi hotspots

Typically, wireless routers act as Wi-Fi access points for phones and computers. And the Internet source for routers is wired Internet service providers.

But mobile phones can also act as a Wi-Fi hotspot. At the same time, the source of the Internet on them will be a mobile Internet provider or Wi-Fi connection.

What is needed for the phone to work as a Wi-Fi router

All Android phones can act as a Wi-Fi router for other devices.

But it is also necessary that the phone can use the mobile Internet. Since the computer that you connect to the Internet can automatically download updates and consume too much Internet, it is advisable to buy a mobile traffic package in advance.

How to turn on Wi-Fi for other devices on your phone

To enable mobile hotspot, make sure you have mobile data turned on.

Note: modern phones can distribute mobile Internet or they can be connected to a Wi-Fi network and distribute Internet through a wireless Access Point at the same time. This can be useful if you do not know the Wi-Fi password or want to temporarily connect other users to the Internet without giving them the Wi-Fi password on the router.

Now go to the settings, this can be done by clicking the gear or the “Settings” icon among the applications.

The menu names may vary slightly, but most likely you need to go to the “Connections” item. Perhaps already in the main menu you will see the section “Mobile Hotspot and Tethering” – go to it.

Find “Mobile Hotspot and Tethering”.

You need to enable “Mobile Hotspot”, to do this, move the lever.

Depending on your phone model, you may need to disable Wi-Fi connection to enable mobile hotspot.

What is the Wi-Fi password for mobile hotspot

To see or set a password instead of enabling Mobile Hotspot, click on it to go to the mobile hotspot settings.

Here click on “Configure” to change Mobile Hotspot settings.

Here you can change Network name

and Password.

It is recommended that you use a password to prevent strangers from connecting to your phone's Wi-Fi. Connecting outsiders is bad for many reasons:

  • excessive consumption of mobile traffic
  • security of other devices connected to the phone
  • faster battery drain
  • an outsider can use your Internet connection for crimes or illegal activities (and you will have problems)

How to check who is connected to a mobile hotspot

In the “Mobile Hotspot” menu you will see Connected devices.

Why does my battery drain so fast when using mobile hotspot

When your phone shares Wi-Fi with other devices, it does not go into sleep mode, but constantly uses the Wi-Fi module and modem for mobile Internet. Working as a router also creates a load on the processor.

There is nothing you can do about the fact that the phone runs out of power faster, but you can leave it on charge while the mobile hotspot is running.

How to keep track of your mobile data usage

You can track your internet usage in the app or website of your mobile operator, or on your phone itself.

Find “Data Usage” in the menu.

Here you can:

  • see how much data was downloaded in total (via mobile networks and Wi-Fi)
  • view data consumption in certain periods
  • check which apps are consuming the most data
  • set warnings and limits when a certain threshold is reached

Why does my phone not switch to mobile Internet for a long time (SOLVED)

Posted by Alex On June 9, 2021

A Wi-Fi connection is generally faster and more stable than a mobile Internet connection. Therefore, when possible, most users use Wi-Fi, which is usually free and unlimited. At home, at work, sometimes even on public transport, we connect to Wi-Fi and enjoy a good quality Internet connection.

When you disconnect from Wi-Fi, your phone is set to switch to mobile internet so you can stay online at all times. You may have noticed that if you are already quite far from the wireless Access Point (for example, you left the house), then the Wi-Fi connection icon will still be shown on the phone, albeit with a weak signal, but if you try to use the Internet, then it may turn out that the connection is actually missing.

In this article, you will learn how to turn on the hidden setting on Android phones to quickly disconnect from Wi-Fi when the signal is weak.

To find this setting, you need to enable Developer options.

To enable Developer options, open the Settings screen, scroll down and tap About Phone or About Tablet.

We need to find an item with information about the build number. Scroll down, you can probably see it right away. If not, look for items like “Software Information” and navigate to it.

Find “Build number”.

Tap the Build number box seven times to enable Developer options. Press a few times and you will see a countdown toast notification that says “You are now X steps away from the developer”.

When you are done, you will see the message “You are a developer now!” Congratulations. Don't let this newfound power hit you in the head.

Press the Back button and you'll see the Developer options menu just below or just above the About Phone section in Settings. This menu is now enabled on your device – you don't have to repeat this process until you've done a factory reset.

So, go to Developer options.

In the “Network” section, find the item "Aggressive Wi-Fi/cell handover”.

The comments to this point say: Switch from Wi-Fi to mobile networks more quickly when the Wi-Fi signal is weak.

That is, if the signal is really weak and the power of the phone's transmitter is simply not enough to deliver data to the router, then disconnection from Wi-Fi will be performed. This situation is not uncommon: the phone sees the signal from the router, but the router cannot receive the signal from the phone, since the router has a more powerful transmitter and, as a rule, external, larger antennas.

While using Wi-Fi, the phone is still connected to mobile networks to make calls and send or receive SMS. But the Internet connection on mobile networks is turned off. As a result, when disconnecting from Wi-Fi, the phone takes some time to establish an Internet connection on the mobile network. You can enable the “Keep mobile data turned on” setting.

A note to this option says: Keep mobile data turned on at all times, even while Wi-Fi is in use, to make it quicker to switch networks.

As a result, when you disconnect from Wi-Fi, you can immediately use the mobile Internet without delay in connecting to it.

Most likely, turning on the last setting (Keep mobile data turned on at all times) will lead to a small additional traffic consumption. And enabling the option to aggressively disconnect from Wi-Fi when the signal is weak can increase the number of disconnections if you often have a weak signal.

Therefore, experiment with these options – they may make communication more or less comfortable depending on your specific conditions. The final decision on their use you need to make after checking in practice how they suit you.

How to check if my router supports IPv6

Posted by Alex On June 7, 2021

How to open a site on IPv6

The fastest and easiest way to find out if a router can work with IPv6 is to check if it can open a site with an IPv6 address. Use the service “Do I have IPv6”. This website allows you to connect to it in a variety of ways – just follow the link and you will see if you can connect to IPv6 addresses. If you have an IPv6 address, this automatically means that your router supports this protocol.

But if this site writes that you do not use IPv6, then this does not mean that your router is not IPv6 enabled – it is quite possible that the whole point is in the Internet provider, many of which do not yet know how to work with IPv6.

Take a look at the settings of your router

You can go to the control panel of your router and if you see the settings for IPv6 there, it means that there is support.

This router has an “IPv6” tab and even an assigned IPv6 address. But in fact, IPv6 addresses from fc00:: to fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff are local addresses. That is, the router creates a local IPv6 network, but due to the fact that this Internet service provider does not support IPv6, it is impossible to connect to IPv6.

Global addresses currently can only begin with 2 or 3 (others are simply not being distributed yet).

How to check on the command line if the router can work with IPv6

If the router supports IPv6, then during automatic network configuration, the network interfaces of your computer also receive settings for IPv6. Therefore, even if you did not specifically configure and even if your ISP does not support IPv6, your network interfaces will have IPv6 addresses.

On Windows, run the following command at the command prompt: 

ipconfig

This screenshot shows both global IPv6 addresses (starting with 2 or 3) and local ones, ranging from fc00:: to fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff. If you also have it, it means that both your router and your ISP support IPv6.

In the next screenshot, only local IPv6 is visible – this means that the router supports this type of addresses, but the Internet service provider does not.

If you do not see IPv6 addresses at all, then your router does not support them, or they are disabled in its settings.

On Linux, to view IPv6 addresses, run the command: 

ip -6 a

This screenshot shows both global IPv6 addresses (starting with 2 or 3) and local ones, ranging from fc00:: to fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff. This means that both the router and the ISP support IPv6.

In the following screenshot, only local IPv6 is present – this means that the router supports this type of addresses, but the Internet service provider does not.

If you do not see IPv6 addresses at all, then your router does not support them, or they are disabled in its settings, or in the operating system settings – this is also possible.
