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?<br>

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.<br>

Hi Paolo,<br>
<br>
Will it be possible for you to check with WEP authentication? Just to
make sure, its not dependent on the authentication method. Due to this
connection issue, I have started using Wired Connection. I know its a
security issue, hence its even OK if you can't change the
authentication method. Thanks in advance.<br>
<br>
Regards,<br>
<br>
Kurian Thayil.

I setup a WEP connection and it connected just fine. It's been running
for about 10 minutes with no disconnects. I'll keep running for a
while. I've been doing updates to try to keep the network busy to see
if that has any effect.<br>
