Downloading is fine, and I get the expected 1.3k+/second download rates, but it slows to an average of like 50 bps when I try and upload. What seems to happen is that the modem sends in very short bursts "bursts" at close to full-speed, then idles for a minute or more before doing the next one. Before this happened, I had no problems uploading from my computer.. This is causing problems with trying to do things like cvsup (it sends out about 180 protos, and then sits there doing nothing for the next 10-15 minutes before dying with a "Detailer failed: Premature EOF from server". I was running current from about Oct 21 or before when I first noticed the problem - I've just downloaded the entire src tree from the 27th, make world'ed and made a new kernel, but the problem hasnt gone away. Is this likely to be a problem with the OS, or a hardware problem with my modem? Kris
