I've just installed Arch on my laptop, an Acer TimelineX 3820TG, and had my wireless internet working just fine when I sat right next to the accesspoint with a link quality of 70/70 and bit rate of 130Mb/s.
However, when I moves to another room (like 3 meters away from the AP) the quality went down to 47/70 and bit rate to 52Mb/s and the internet pretty much stopped working! When I'm in Windows or Ubuntu (as I ran before) there's absolutely no problems with my connection.
lspci says that my network controller is "05:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)"
And the way I'm gaining access to my AP is through "wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf && dhcpcd wlan0"

Some more info:
I'm running x86_64 version of Arch on kernel 2.6.38-ARCH
Now I just changed the network to networkmanager and connectiong by nm-applet but the problem still remains.

And here's when it has started working again:

I think I've found something here:
https://bugzilla.kernel.org/show_bug.cgi?id=31452
At the end, there's a patch. But, how do I apply it? I've tried to download and ran "patch < tmp.patch" but it says file can't be found.
EDIT:
The method: "Creating /etc/modprobe.d/ath9.conf with : options ath9k nohwcrypt=1" worked! But I'll wait with the solver marking until I get the question above answered so I can do it the "correct" way.

Are you just trying to run the patch from an arbitrary directory? This will obviously not work because a patch must be applied to source code. If you are serious about trying the patch you will need to download the kernel source, extract it to a directory and then run "patch < tmp.patch". Maybe try adding this line to the PKGBUILD in /var/abs/core/kernel26 or one of the many kernel26 PKGBUILDS in the AUR.

Great things come in tar.xz packages.

Thanks!
I guessed it was something like that, seems to hard for me now. When I've started to get everything to work here I don't want to ruin my install by perhaps doing something wrong.
