Can't connect to lots of sites using Wireless

[arthurlag]

It seems that i can not connect to lots of sites including facebook, using any browsers. Does anyone might have an idea why this might happen because i couldn't see any similar problem.

using the built in wifi , i get that issue where it simply silently stop working (the network manager still show as connected, but no packets can be received or sent), manually reconnecting usually allowed me to browse a few more minutes before it happened again. Lowering the txpower on the wifi pretty much fixed it for me when it came down to regular browsing, but downloading at a stable rate was out of the question, so now im using a wifi stick.
