Hi All,
Since the installation of F12 in my Acer Aspire 580 series laptop with
Intel 3945ABG wireless module, I am having the issue where my Wifi link
gets deactivated and activated (disconnects & connects) frequently.
AP is a Netgear WGR router with WEP enabled. Was using Debian GNU/Linux
(Etch & Lenny) and I was able to work without any issues. The
following is the /var/log/messages when a typical wifi session is
disabled and enabled. This issue was severe when there was no security
enabled in the router (I gave only MAC address level security). When I
included WEP, it became better. Module iwl3945 is loaded in the kernel
along with iwlcore, mac80211. Any idea on how to avoid this completely?

I also have a 3945ABG and I see no wifi issues with F12. However, I
use WPA authentication. I have on rare occasions had some of my
connections get dropped while transferring data while other connections
(even to the same system) remaining active.
