Hi All,<BR>
<BR>
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>

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>
