Thanks. I have checked memory for over 4 passes. its fine. I have no problem with XP. UBUNTU checks the hdd during boot. It has not reported any error. So the hdd and mother board is fine. I see in UBUNTU, Fedora and OpenSuse fora similar problems are being voiced by many. I beleive Linksys and Asus are good hardware manufacturers. Graphics are integrated and I do not have a separate card. It appears that the Linux kernel has this problem with ( its RT61 equivalent) driver even if NDIswrap is done. Since this problem is not only with Linksys but also Netgear and many other brand cards.
Ofcourse I am forced to continue use of windows xp under the circumstances. However I will not lose hope. The reason I posted this is if any had similar problems and solved. Also the Linux user community may put pressure on Linux Kernel developers to develop a Kernel which addresses this problem. Now I installed openSUSE 11.0 with KDE 4.0. It appears good. But I find that it is using only 800x600 pixels of my 17" monitors 1280X1024.. Everything is so small scale that I hardly can make out the names etc. I need to connect my wireless internet. I do not find even the terminal or how to access it. First priority to increase screen size. In openSUSE fora I also find this problem. Some one suggested sax2 but how? Edit xorg.config again how? I do not find a file search location. -Mohan.
