I have buy the modem "U.S. Robotics Sportster 56K Voice Faxmodem" and I want to know how can I set my modem speed to 56K. Since, I had tried it in the Control Panel --> Modem --> General --> Content, I can only find that my modem can only connet to max. speed of 115200. What is the meaning of the "115200"? Moreover, when I connet to internet, I find that the connection speed of my modem is at most 33,600bps.

115200 means 115200 bits per second.. which is roughly equivalent to about 100k/s. this is not possible, but that is the speed that you could put it at. a better value would be to put 57600 becauese that would work just as well, or might even make your connections faster.

secondly, very rarely can you connect at 56 K (impossible!) the most you get is about 52-54K and like you say, probably more likely then not at speeds of 33.6kb. this is caused by a few reasons.

1. your isp is not 56K compatible, either you are using kflex, X2 or v.90 and something is different along the way

2. your phone lines are not digital and have lotsa line noise.

therefore dun expect too much out of the modem. you should be able to connect at 40-44k when nicely set up, but that's about it.

another point, download speed might be higher than 33.6 k, but upload speed is always 33.6K

Go to My computer, Dial-Up Networkind, get the properties of your ISP conection. than  set max speed to 57600 and tick connect only at this speed. Now hit the connection tab, than advanced, where it sayes extra settings type    at&f    
there are orher thing you can do to the regstry if this dos not work

maybe your isp's max speed is 33.6

I can't solve my problem yet.
However, I can ensure that my modem connect at 33,600bps exactly and my ISP supports 56K.
Will it be the telephone line problem or others?

In supplement to MATTCEI's answer, you can verify whether your modem supports x2, FLEX or v.90 by going to the Hyperterminal and typing ATI7. This should shows the what the firmware of you modem supports under the "options" line.

    Doulbe check with the ISP whether they support any of the standards listed in ATI7.
