Summary: Wicd solved freeze and frequent wireless disconnects on Acer
Aspire 4736z, Atheros AR928X wireless card.
I bought a new Acer Aspire 4736Z laptop with an Atheros AR928X Wireless
PCI-e card in it one week ago.
By booting the system with a Gentoo LiveCD and checking the kernel
modules I found that the right driver is ath9k module, I connected to
wireless networks by engaging the iwconfig command, everything was
running smoothly but when I installed Gentoo and booting the system I
couldn't stay connected more than 10 min and I had to unload the module
by modprobe -r ath9k and reload it again.
I came to this Ubunto bug page and I decided to use Wicd to connect to
wireless networks and now the problem is gone ! just wanna say thanks to
you guys and also it's good if somebody tell me what's the difference
between setting the wireless network up by "iwconfig" command and "wicd"
?
Something that might help is that by setting the network essid by
iwconfig command I couldn't get Access point Address but I had the up-
time of about 10 minutes but when I connect by wicd the output of
iwconfig shows that Access point Address is associated:
iwconfig:
lo no wireless extensions.
sit0 no wireless extensions.
wmaster0 no wireless extensions.

The only reason for this post is just to help the open source society and also
upgrade my own knowledge.
Thanks a lot.
