Hello.

I had problems with wifi since build my pc. These are my specs:
AMD FX-6300
Sapphire R9 270X 4GB DUAL-X OC & BOOST
Asus M5A97 R2.0
Ripjaws X DDR3-1866 2x4GB
XFX TS 550W 80+ Bronze

The first wireless card I had was TP-Link TL-WR741ND but I encountered a lot of troubles of ping and disconnections. Then I decided to bought a new wireless card TP-Link WDN4800. That card didn't solved my problem.
I don't know why but one day I changed my bios's profile from "Normal" to "Optimal" and the connection was a lot better but sometimes is poor (now I have 1 bar, sometimes 3).

What can be causing this trouble? I am really tired.
 
Solution
Do you have the latest BIOS and mobo drivers? They are constantly updating to increase best compatibility with add ons like your wireless adapter
