I just built a computer and installed a 56k modem.  I have tryed every setting I can think of to make it connect to AOL at 56k.  Still, it only connects at 28.8. I don't think it's AOL because other people dialing to the same access number are getting the connection.  Please help.

Are the correct drivers installed, what type of modem is it.  Your phone line may not be able to handle 56k.

It doesn't matter if you have a 56k Modem because the maximum connection spedd for a 56k Modem is between 42,000-48,000 kbps, it will also depend on your line condition and your ISP Backbone Links.

Probably your Modem is not compatible to your ISP, if you have a X2 Modem and your ISP uses Kflex Protocol, unless your ISP uses the new standard (v.90).

Incorrect.  I usually get 48000,
and sometimes get 49333 or 50666.
A friend gets 52000 or 53333.

Exactly.

> and your ISP Backbone Links.

Incorrect.  Any ISP has a high-speed connection to the Internet,
leaving your modem as the "bottle-neck" which restricts
the download-speed.

Ok, the Feds limit ANY asyn speed to 53K so as to let the telco's make their money on 56K frame links. So like it or not, you'll never get 56K and very rarely will you get 50-53 unless you are within a short distance of the CO for your area.

With that in mind, why wouldn't you be getting the same connects as your friends? Provide with a model, but I think the problem is either an X2 or KFlex modem that hasn't been upgraded to v.90. Also, check with AOL on the specific number you are calling.. Alot of AOLNet still only supports v.34, and some of their locations even let the overflow modems in a 56K pool be older.. Philosophy is that at least you can connect..

Finally, heres the real kicker. Technically the v.90 standard is still open, and implementation of the standard still a bit shoddy. If you can, just reflect on the original war of USR & Hayes on above 9600... That was ALOT of fun!!

Nonsense.  :-)

The problem is that the "strength" of a 56K signal is
very large -- some of the signal "bleeds" into an adjacent
pair of copper-wires in a bundle, thus impairing the
quality of some other person's voice (or modem) connection.

See: http://www.56k.com and/or http://www.v90.com
which includes information about the finalized (February 198)
V.90 standard.

Alright even thought it is officaly 53k One of my friend connects at 56k all the time, though he dials a server a few miles away and all the lines arounds here are brand new.  
Also to drominore I get 52 and I have old lines in my house plus I am dialling a server 60 miles away, but I suspect that has something to do with the new fiber lines that were just layed in my area.  

And..
were is WoW he has  not posted one comment on this question since he posted this q on Oct. 28th???

> One of my friend connects at 56k all the time,

Then, he is observing the speed between the motherboard
(and the COM port) to the modem, *NOT* the speed between
your friend's modem and the ISP's modem.

See: http://www.56K.com  for details.

Your modem sends "analogue" information,
over your house-wiring, to the nearest telephone-exchange.
At that point, the data is converted to "digital",
and can be sent 60 feet or 60 miles or a light-year
with *NO* loss of "quality".
So, the fiber-optic lines just increase the *speed* of
the transmission of the "digital" data, and also increase
the number of "simultaneous" circuits (like widening a highway to more lanes).

Set the COMx port to 115200, and then try to connect,
using your 56K modem.  If that 3rd-party program
reports 115200, then it's wrong (or you are misinterpreting its output).

Also, start HyperTerminal, and issue 'ATDTxxx-xxxxx'
to connect to your ISP's dial-up number.
Watch for the 'CONNECT mmmmm/ARQ/V90/....' string,
and report the value for 'mmmmm'.
I doubt that it will be '56000', anywhere in North America.
