finalewiz Posted March 1, 2005 CID Share Posted March 1, 2005 Hi everyone. I'm totally stumped! I have a Comcast connection in Dallas, using a Toshiba PCX1100 (originally from RR in Oklahoma City). About 4 months ago, I noticed an issue with my upload speeds (download is a consistent 3200Kbps). Anytime I upload large files (>2MBs), the upload speed starts out at 250Kbps (as advertised). Within about 2 minutes, it has steadily reduced itself to a steady 60Kbps or so. It stays there for the duration of the file, then starts all over again at 250Kbps with a new file, reducing itself to 60Kbps again, and so on. This is bad, as I routinely upload large audio files to a studio - usually 80 MB's each or so. I've tried this on all three of my machines, one with a brand new installation of XP SP2. Two machines are 802.11G, the main one is Cat-5 - no difference. I've tried it with three different FTP clients. I've tried it with my computer connected directly to the Toshiba PCX1100. All to no effect. I've done a DSLReports quality of service test - passes fine. Good latencies, good pings. Everything looks good. Comcast swears that they are providing the right level of serice - a steady 256Kbps upload speed that would not be throttled down past a certain upload size. All I can see is it might be the modem, or a XP setup issue. Can anyone shed some light on this? Thanks! Quote Link to comment Share on other sites More sharing options...

finalewiz Posted March 1, 2005 Author CID Share Posted March 1, 2005 No, it's not the USB version - just ethernet. I'll look into the PCX2600 on ebay, but I really would like to know if it's really a cable modem issue. Quote Link to comment Share on other sites More sharing options...
