How to use an Android device as a WiFi signal booster?

How to use an Android device as a WiFi signal booster?

If you have a weak WiFi signal at the other end of the house, a WiFi repeater would come in handy. If you don't have one, and you have an Android phone that you use poorly, you can use it for just that purpose.

WiFi repeater works, simply put, by receiving a WiFi signal, amplifying it, and transmitting it again. So, if we place a WiFi repeater somewhere where the WiFi signal from the router is weak, it will amplify it and spread it further. In this way, with a third device, we can get out of range of the WiFi signal emitted by the router and catch the one that re-transmits the WiFi repeater. The downside is that it reduces performance, but better anything than anything.

Ok, how to enable this option on an Android phone? There are two variants and the third one concerns the Galaxy S7 phone (but in that case the sentence from the first paragraph falls into the water: and you have an Android phone that you use poorly).

1. variant: root

There is an application that solves everything in a few steps, but it is mandatory to have a rooted device!

  1. Install fqrouter2 (how to install .apk file)
  2. Turn on WiFi on your phone and connect to the network you want to rebroadcast
  3. Launch the application and allow root access
  4. Go to the "Wifi Repeater" section, tap "Configure"
  5. Enter the correct WiFi network name for the SSID and the network password for the Password
  6. Save and turn on

It may not work. You have "Disable P2P" in the Config window, so try it. Sometimes you will have to turn off P2P yourself.

2. variation: no root with Bluetooth

This is, let's say, an artificial WiFi repeater because we actually send the internet from the phone (either mobile or WiFi) via Bluetooth. We know that BT has a range in the theory of up to 100 meters (in practice about 30), so we create a Bluetooth hotspot in that radius.

I suggest that you first read the article where I wrote about ways to share the Internet from Android devices, where you can find out the advantages and disadvantages of each of them.

  1. Connect to a WiFi network you want to share
  2. Go to phone options and find the "Tethering" section
  3. Find the "Bluetooth Tethering" option there and enable it
  4. Now just connect to some device via Bluetooth and you will have internet
Find the "Bluetooth Tethering" option there and enable it

3. variant: Galaxy S7 WiFi repeater

This is an option available in Galaxy S7 phones and is very easy to activate. Not to be confused, this option is integrated into the system itself and works by amplifying and re-broadcasting the WiFi signal of the network to which you are connected. So, like the purchased WiFi repeater.

  1. Connect to the WiFi network you want to share
  2. Go to settings > mobile hotspot and tethering > mobile hotspot
  3.  Now tap "More" in the upper right corner and then "WiFi sharing"
  4. Select "Enable" and close the notification.
  5. You will now see the "Mobile hotspot" screen again and turn on the option (the button is below the "Sea" I mentioned in the third step)
  6. The phone will now share the WiFi network you are connected to.

If you turn off WiFi on your Galaxy S7 and turn on mobile data, the phone will share that internet and not WiFi.

Note: this option is only available in the latest Samsung devices, so Galaxy S6 or A 2016 models do not have this option!

If you know of another way, write in the comments :)

If you don't have a surplus of Android devices, or you find all this complicated, you can buy WiFi Repeater quite cheaply.

The difference between Sleep, Hibernate and Hybrid sleep options

By Administrator
What is the difference between regular Sleep mode and Hybrid sleep mode? And what is Hibernate ? I will try to explain in the simplest way possible so that everyone understands nicely. 1. Sleep When you select Sleep mode , all components of the computer except RAM are shut down to store data. So, if you do something on the computer and press Sleep, the computer shuts down and everything you did (left open windows, documents, etc.) is stored in RAM.

SIM card sizes (Mini, Micro, Nano) - explanation

By Administrator
Many users still complain about the size of SIM (subscriber identification module) cards. Which one goes on the phone? Can it be shortened? Can a smaller one into a larger slot? Although we are slowly switching to eSIM (more on this in this article ), we still use classic SIM cards. Newer phones usually require a Nano sizes, but operators issue SIM cards in all sizes. More precisely, now SIM cards are made so that the user can choose the size immediately, and later change it if necessary. More on that at the end of the article.
