Strange upload slowdown issues - help!

« on: March 01, 2005, 09:22:17 AM »

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!

I think alot of your issues are because of this. The slow down is because Comcast just ^graded everyones connections, and with that modem i doubt your router can or will recieve the new cap packet from Comcast, if anything making your connection slower . If i were you id look into something a bit more recent, like mabey the PCX2500 ( which is what most folks are currently now runing, altho the 2600 is out) and i believe you'll see quite a difference.

[edit]

Also i see that its usb? That wil also decrease speed massively.

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.
