i can provide more info if you need, tryed to install driver from https://github.com/lwfinger/rtlwifi_new, but nothing changes.what i can do????

i read this on driver page

The ONLY option you are likely to need is "ant_sel". The penny-pinchers at some laptop vendors, mostly HP, decided to save a few cents to install only one antenna. That would not have been a problem as the driver contains the logic necessary to handle this case; however, the idiots failed to correrctly encode that information in the devices ROM. Accordingly, the driver follow the ROM setting and uses the WRONG antenna. Effectively, the device has NO usable antennas.?

please help me to adjust sigmaal level!
