I too have this problem. I have a Samsung R620 with a RealTek 8192E and
Ndiswrapper runs OK until I transfer a large file. It usually fails
quickly - after a few tens of Mb transferred.
If I open the Windows Wireless Drivers control panel and remove then re-
add the WinXP driver then the wifi comes back to life. Until it dies
again.
