try to disable the V90 protocol on the modem, the way v90 works is it connects at the best speed it can, then after its connected if the line is noisy it dynamically drops the speed without dropping the connection, the speed can go back up after..but yeah sounds like it could be a compadiblity issue with the isp
all i can suggest at this point is turn off V90 (see your modem docs to do it, its usually one of the AT commands) and try again, nate On Thu, 6 Jan 2000, Shao Zhang wrote: shao >aphro [EMAIL PROTECTED] wrote: shao >> the subject is a little misleading :) shao > shao > sorry... shao > shao >> shao >> is the server you are testing from a local server? within your ISP's shao >> network? shao > shao > Neither. shao > shao >> what speed do you connect at(see /var/log/messages) and what kind shao >> of file are you trying to transfer?(text? compressed? highly shao >> compressed?) and what mode?(ascii/binary) shao > shao > It connects at 33600.
