Same problem with Dell 1420n laptop after I installed Gutsy. The fix is to use the old iwl3945 and blacklist the ipw3945, this does fix the stability issue but it's slower. I was maxing out 8100kbps dowloads with the ipw3945 but then it drops connection after a few minutes. Now with the iwl3945 I'm only maxing 1204kbps but it's stable a trade off that's not noticed unless you update or apt while on wireless. Here's the fix from dells wiki http://linux.dell.com/wiki/index.php/Ubuntu_7.10/Issues/ipw3945_Wireless_Network_Module_Issues
