Wi-fi on windows 8.1 and linux mint 16-17

Question

linux

I wanted to transfer the laptop to linux mint 16 or 17. But I noticed that where windows 8.1 caught the network signal at maximum quality, etc., Linux either does not catch it at all or has a very poor signal level. The laptop has a wireless module from realtek. I was not too lazy to test the reception quality on different operating systems and saw that such nonsense is observed on any linux distribution.

Answer 1

Perhaps installing nonfree firmware will help.
Or, as an option, you can try ndis wrapper en.wikipedia.org/wiki/NDISwrapper

Answer 2

The question is, is this when running on battery or mains? In ubuntu, when running on battery, the power saving mode for the wi-fi adapter is turned on and the pings increase sharply.
Run iwconfig and look at the adapter details.
There will be network quality, signal-to-noise ratio, connection speed, whether power saving is enabled, etc.
