I'm writing this on a wired connection because the wireless keeps disconnecting. Has anyone else had this problem and is there a fix? Here's my network details:

The wireless disconnects and then never reconnects, but attempts to do so constantly.

Edit: The computer is a Samsung 350V5C.

You can have a look here How do I prevent WiFi cycling between connected and disconnected?. To check whether you have that conflicting module use lsmod | grep acer –  Web-E Apr 15 '13 at 15:30
    
Thanks for that, but it looks like I don't have the conflicting module (acer_wmi). I've added the lsmod details to this post if it helps. –  babbaggeii Apr 15 '13 at 16:07
    
2.4GHz cordless phones can kill WiFi connections with no debug trace that I'm aware of. –  msw Apr 15 '13 at 16:29
    
I've turned off anything that transmits at 2.4GHz and it still disconnects. –  babbaggeii Apr 16 '13 at 15:02
