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.

Hi Paolo,
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.
Regards,
Kurian Thayil.
