1. Stay wired.
2. Try latest firmware and drivers.
3. My WUSB-11 is now... history.
4. Try another USB dongle thing.
5. Improve the antennas. See www.freeantennas.com/projects/template/
Best of luck,
A few years ago I purchased a USB wireless adapter. The device has always cut out during dopwnload. I now use a VOIP service called Skype and the connection drops out and loses connection and then resumes it a few seconds later. This results in a loss of conversation. I also never did totally stream audio or video well without dropping out either. When connected to ethernet cable direct to router it seems OK. Does not drop at all with same router.
Gateway P-4 1.5G Intel MB, 512 RAM, Tried a 802.11 b Linksys router as well as a 802.11G D Link, Both act the same. XP Home SP2, Adelphia cable router.
