I have a Motorola SM56PCI modem that will not connect at any speed over 28,800.
The previous modem I had was able to get up to 39,000 on a slower computer at the same location.
The Motorola tech support had me add this string: AT&F&C1&D2*MM15    
I told them that didn't work, so they told me to get a hardware modem!
Can you please help me get a faster connection?

Surf to: http://WWW.56K.COM
and read "Troubleshooting Guide"
and "Help for slow connects".

Does your ISP support K56Flex or X2 or V.90 "flavours" of high-speed connects?
Perhaps, your old modem was the same "flavour" as offered by your ISP, while your new modem is a different "flavour".

Is it the EXACT plug the other modem was plugged into?
Could be the jack or cord that is slowing it down.

try to lower the modem port speed to 57600 in control panel/modems/properties...
set your modem to software flow control in control panel/modems/properties/connection/advanced...
just use init string AT&FX, which will put your modem back into the orginal mode...
and of course check on all physical issues. line noise can occur suddenly if your phone company has done any work around in your area...they can check that for you...

ANGEL30166, welcome to Experts-Exchange (first login 5/14/00).

Within E-E, experts usually post "comments" for the author to try, rather than "proposed-answers", especially when experts use words like "try" or "check".

Please select "change-answer-to-comment", and let the author of the question decide which comment solves the problem -- the author can always use "accept comment as answer" to "upgrade" a "comment" to become an "answer".

Thanks for following the E-E protocols, and welcome to E-E.

> Now get speeds up to 115,200bps

Sorry, but you are seeing the speed between your modem and your motherboard, not the speed between your modem and your ISP's modem.

Add 'W1' (or 'W2') to "extra settings" in the "advanced" setup-properties for the modem, and Windows will report the modem-to-modem speed.
