Odd WiFi Issue
Hi
I've just installed openSUSE for the first time. At work (Video Networking) we have started using a new product from CISCO based on SuSE linux servers; to try and get up to speed fast I've installed openSUSE on my home machine (HP nx7400 laptop). I'm impressed so far especially with the no hassle instalation. Though I have found an odd problem with my Wireless connection. The wireless chipset is an intel 3945ABG. It works fine in Windows, but in SuSE when I go to Network connections - New connection - Wlan0 and look at the availible connections, it lists several access-points (variably) but not all the networks in my area and it never finds mine which is all of six feet away! I'm guessing this is going to be a driver issue as I know the hardware is fine. Can anyone get me started on how to track down this problem. Cheers J

Images include use of smilies, the BB code [img] tag and HTML <img> tags. The use of these is all subject to them being enabled by the administrator. What gives? there's no img tags or smilies

A note of caution, that probably will NOT work on 11.2 as the file naming convention inside the /etc/modprobe.d/ directory is changing between 11.1 and 11.2.

Re: Odd WiFi Issue
OK cheers, I'll probably change the channel if it's just going to cause problems.
It's very crowded in the airwaves around here, so 13 seemed like a good idea at the time, unlucky for some I guess. Thanks again J
