I have a Linksys router and an actiontek usb wireless adapter attached to a desktop running XP Pro, The problem is we are sharing a 3ghz broadband connection and I keep losing bandwidth, If I re-set the router I get download speeds of 380 kb/s approx, but over a short period of time I lose speed, down to 30 - 50 kbs average. I have changed usb ports and tried my brothers usb adapter which is the same as mine to no availe. My brother uses his pda with the same actiontek adapter and has no problems. Is there a test I can do to see why I am losing so much bandwidth. It also doesn't help to reset my machine, the only way to get any bandwidth back is to reset the router.
