From the beginning of the September, I am an owner of Xiaomi MI4C which was one of the best options for its money. All features are great and by far the best for its price range. Anyway!
I was in a lot of situations where there was a wifi
The way to increase the tx power on other brands of smartphones(in most cases) all have to do to enter on a terminal with root privileges
iwconfig wlan0 txpower 30(accordingly)
And then you’ve got a little bit better of reception.
But what about Xiaomi devices? Well, there is the iwconfig but it’s not possible to use it even with root permissions.
Well after some digging I found out that you can change tx power from a .ini file located at /system/etc/wifi on my device but may differ on yours.
Then the only thing you have to do is to uncomment (if exists)
and add a value(don’t overdo it). Restart your android and then happy browsing 😋
