Hi can any one help my modem only connects at 31200kbps when it use to connect at 48000kbps it has done this ever since i have formated my harddrive and reinstalled everything
ANY ADVICE WOULD BE GRATE
THANKS
ROB
 
Find out exactly what modem you have, who made it, what model, etc., and get the latest driver for it.
If you still can't get over 31.2, get back to us, and we'll find some more stuff you can do. Cheers,

Jim's Modems:
 
In the control panel double click on the modem icon. select your modem and go to properties. there is a section on the bottom that states modem port speed OR connect at (or something along those lines. I use Win2K now so I really cant remember too well). Select the highest speed it has. Also check with your ISP and find out if the # you dial is a 56K line or a 33.6K line.
 
might be a coincidence but have you spoke to your telephone provider? ask then to increase the gain, more likely a driver issue though. If in doubt get the Ball Pein Hammer out
 
Hi sorry but nothing has worked well i can't find a new driver for the modem it is a Phonic pro 56k v.90/k56flex PCI could any one tell me the URL which i could download the driver from.
THANKS ALOT

Is the phone cord going straight from the wall to the modem? Sometimes going through a surge protector will slow the connection down considerably (it'll also allow lightning to fry your modem).
 
Is the modem a software modem or a hardware modem ? I suspect you are using a "soft" modem and this might be part of your problem. Most modems are described as Software modem, soft modem, Winmodem or something similar. This means that they need windows in order to be able to run.

If you are using a software modem then changes made to Windows, (like re-installing after reformatting the hard drive). may affect the modems performance. If the windows drivers were set up differently then you will have a problem, (such as lower speed).

The alternative to a "Software modem" is a "Hardware modem". The difference between a Software and Hardware modem is that a soft modem needs to interact a lot with the processor and the Operating System. A software modem slows down the processor and will only work with WIndows. A hardware modem has minimal interaction with the processor and will operate on any operating system.

If you find you cannot use this modem to run Linux then this is a giveaway that you are using a soft modem.

All soft modems have a high degree of interaction with the processor and OS and even though they are rated at 56K they cannot deliver 56K. This is because of the overhead of interacting w/processor. They are processor and OS dependent.

Hardware modems are not dependent on the operating system. They typicaly have 80% less interaction with the procesor. Hardware modems rated at 56K are much faster than their soft equivalent.

Hardware modems are always faster than software modems. A 56K hardware modem will not deliver 56K because it too has some overhead but I can say that the one I installed on my PC at home will is giving me 44K right now.

I have a very noisy phone line, my neighbour is a CB radio enthusiast, and the line quality was tested using a special meter. On a scale of 1=low to 10=high my line tested at 3.4. On a soft ISa modem I had lots of random disconnecs. Up grade to a soft PCI modem stopped the disconnects but was slow, the "cure" for me was a PCI hardware modem that I bought from ebay for forty dollars.

Hardware modems are more expensive than software modems and unless you specify otherwise most stores will use soft modems. When you bought your PC did you specify a hardware modem ? If not then you almost certainly have a software modem installed.

Most hardware modems are ISA and this slows them down a bit. They run on the ISa bus which is slowerr than the PCI bus.
I would buy and install a hardware modem that runs on the PCI bus. If you like you can leave the software modem in the machine then you can try the Hardware and Software modems side by side, unplug the phone cord form one, plug it into the other one rebbot, reconnect and and see which one performs best and gives the best speed.

If you have any questions send me an email eugeneokeeffe@hotmail.com

Hope this helps

Here's a few things for you to check and know:
1. You say the modem is a V.90/56K-Flex; make sure the number you use for your dial-up is V.90 or 56K-Flex, not X2 -- there is a difference.
2. You say you are having trouble getting the drivers for the modem. Are you using generic drivers in Windows? If so, you probably are not getting V.90 on the modem. The higher speed connection you are used to were probably while connecting at V.90, not 56K-Flex.
3. While the suggestion you got earlier for setting the port speed to max is good, you need to limit the setting you select to one level above the 56K you think the unit should run at. Choosing a higher speed will tell the network you are connecting to that your modem has more capability than it really has. This will prompt the network to "step down" its compression features when downloading to you and will actually result in a slower connection for you.
4. Keep in mind that your connection speed is based on the quality of the connection you get through the phone company. If the phone company has changed the routing on your line, i.e. they have switched your number to a different set of switching equipment which is farther from your home (I believe the limit for 56K is 1/3 mile), then you will not connect as fast as you used to. Remember, a connection speed of 56K is theoretical (a lab clocked speed under ideal conditions); you will very seldom see it in reality.
