[Bug 426130] Re: freezes when using Atheros-AR928X

[Kurush]

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.

wmaster0  no wireless extensions.

kernel : 2.6.31-gentoo-r6

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