I cant think where to look for this problem. Perhaps someone can help me. If I run kernel 2.6.16-1.2133 my ipw2200 wireless works well. If I use a newer kernel (such as 2133 or 2157) it works fine in level 3 text mode, but starting Gnome causes it to stop after a few seconds or a couple of minutes. I can't restart it except by rebooting. I don't know why something can be so variable, and don't know where to go from here. As far as I can see, no logs tell me anything. Output from ifconfig and iwconfig seem to be the same before and after this occurs. Thanks for any suggestions. DP Adelaide South Australia
