Have a compaq laptop with a winmodem. Couldn't get above 28.8 using it. Bought a USR Sportster 325686-03 external. Can only get 28.8 with this too. ISP verified that their modems are v.90 and 56k. Never see above 3.5k upload speed. Trying to increase my speed. I know just enough to be dangerous and was hoping someone could look below and see if they see any problem. Thanks in advance.

I'd taken a look at the a/d problem before. Was hoping that perhaps something else besides that would be the problem. Thanks for replying. Is there anything else that I could change
that might help increase my speed?

Once again, thank you for your reply.

The difference of 24 between your 3750 and 3300 values in aty11 implies a line that is not 56k-compatible;

In this case, you might get slightly better connect or throughput if you disable 56k on the modem. Shorter handshake, and possibly a better V.34 rate.

While it's possible that you might be able to get a 56k rate to some ISP at some time (if the moon and stars are right), chances are that if that were to happen, it wouldn't be a good rate, and it probably wouldn't hold...

Aloha! Richard.

Thanks for the reply. Figured it was a problem since I am a few miles from the nearest town.
