I have a weird problem pertaining to my download speeds on just one computer in my network that is running WinXP-32. I have Charter with 30 Mbps/4Mbps, and when I try to do a Charter speedtest with this computer I only get between 1-2Mbps download, but upload is still strong at 4Mbps. Most of the time I get ping speeds between 40-100ms and an error that the download or upload file wasn't read correctly and it doesn't complete at all, and when it does happen to work I get the limited speed. I don't know what I did to mess this one up, but it is frustrating. I have tried uninstalling my COMODO AV/Firewall, switching wireless adapters, clearing pagefile and temp folder, and defragging. I know this has to be a setting or something that I inadvertently changed/corrupted in WinXP, because when I dual-boot into Win7-64 (separate primary partition on same drive) I get 40Mbps/4Mbps with 4-10ms latency without a hitch using the same WiFi adapter. Other computers on this network have no problems with their speeds either. What did I do to mess this up on just the one computer, and what can I do to fix it? Thanks as usual for any insights.
