Hello
I'm having a problem for some time with an atheros card 9485 using the
ath9k driver. My computer has linux kernel 3.12.13 and i'm using ath9k
driver from backports 3.15.
The problem that i have is that after some hours of using the computer,
the wireless connection starts
to give problems only with HTTP and HTTPS connections. If i try to load
a page it just stays in "connecting..." but after some minutes its does
load the pages albeit slowly. Its weird because pings work fine, SSH
access to external servers is also fine. I thought that it could be a
DNS thing but if i try to load an http address by IP it also stalls in
connecting....(although i can ping or ssh a external machine by domain
without issues)
This problem happens with both GUI browsers and console browsers like
lynx. The only way to
resolve this is to reboot the computer or power it off. I have also
noticed that if i disable the network connection to my wireless router
when the problem appears and connect to my smartphone with hotspot
tethering im able to load web pages fine again, but as soon as i revert
to my wireless router the problem resumes until i reboot or power off
the computer. Also i dont use any kind of firewall.
My wireless router is a TP-LINK WR542G. Other machines connected to it
dont experience any problems.

Any ideas of what could be wrong?
