Not sure if this is a modem problem
I have a Dimension 4600 with an Intel(R) 537EP V9x DF PCI Modem; I also have Windows XP installed on my computer.
The problem is as follows: when I try to dial into the internet I do not have any problems connecting. However, after about 15 seconds I am disconnected from the Internet. I tried redialing many times and I am never successful at being able to stay on the intenet long enough to be able to surf.
The ISP is sending out around 5,000 bytes but I am only receiving between 200 and 300 bytes; this figure has not changed. My ISP is a free ISP that I have through my job.
I checked out my modem using modem helper and everything is working properly. I have also done
numerous virus scans and spyware scans and nothing has turned up as problematic. At this point, I am at a total loss as to what to do. I thought about uninstalling and reinstalling my modem, but that seems to be to risky as I do not know if my modem is the problem.
I hope that someone can be of help. Thank you.

PayneWhitney,
You can test your modem using a program included with Windows called Hypertrm. Here are some instructions on how to test your modem and check the quality of your phone lines using Hypertrm. These instructions come from Dell's online troubleshooting tools.
To test the phone line quality, perform the following steps:
Click Start, click Run, and type hypertrm. When the program starts, press the key.
Type ATE1 then press . (Your typing may not be visible on the screen.)
You should get the response OK.
Type ATX3DT,18005721959 press .
18003506885 or 18002453828 can also be used as alternate connection numbers when necessary.
(If you must dial 9 to get an outside line, add the number 9 and a comma before the 1.)
After connecting, wait 30-45 seconds for the connection to settle, then press +++ to get the response OK.
Type ATi11 press and look at the lines labeled:
Estimate Noise Level
Receive Signal Power Level (-dBm)
Transmit Signal Power Level (-dBm)
Noise Level:
The Signal-to-Noise Ratio is a measure of the amount of interference is on the telephone line. High interference is generally caused by improperly-grounded cabling, but it can disintegrate signals across a telephone line. This interference can often (but not always) be heard as static, other people's conversations, or clicking.
For 56K connections, this value (Estimated noise level) should be around 100-140. Anything outside this range may indicate line noise as causing intermittent connection drops or low throughput speeds.
Receive Signal Power Level:
The Signal Power level indicates the modem signal amplification. A weak signal may attenuate and not make it to it's destination intact. The guidelines below show acceptable ranges for modem signal power levels.
1 to 9 = Over-amplified signal -- may contain distortion
10 to 24 = Normal, meets 56K connection requirements
25 to 64 = Weak signal – may attenuate (drop off) before reaching destination
If the information you get back indicates a phone line problem, then call your phone company for assistance with fixing this problem. If the information indicates a good phone connection, your problem will most likely lie with your ISP or some settings in the way that the connection is being made with the ISP.
