Hi! I have had a slow modem problem which I have tried (in my newbie way) to solve for several months now (off and on). But I give up! I can't solve this problem with my puny expertise! Can you please help me solve this problem?

Here's the situation:
When I boot into Linux (Red Hat 6.2), I use an external 3Com U.S. Robotics 56K modem (very standard model). Using this modem, as it is currently configured, I get very slow, very poor modem speed (confirmed using modem speed test). However, if I reboot into Win98 and use my internal 56K winmodem, my speed is much better (nearly double the speed). So, I know my slowness has nothing to do with my ISP, with network congestion, etc. My question is: What is wrong with my Linux modem settings? I have no idea how to even begin to approach this problem. (All of the available Linux documentation for modems completely sucks, btw. Unless one is already an expert in telephony/networking.) I just want to figure out why my super-standard modem running on super-standard Red Hat 6.2 is super poorly-configured. Any ideas?

Thanks!!!
Ben

I would get rid of both, and get an internal modem compatible with Windows and Linux and see how it works then. Sounds to me as if it is the external modem, try it in Windows and see if it is just as slow as in Linux. That will determine if it is a configuration or the modem itself.

Ben,

Before you trash that modem (nothing wrong with it), try

http://www.linuxnewbie.org/nhf/intel...odemtweak.html

That might get you going.

Good luck.

I didn't tell him to trash it, I just recommended getting one modem for one machine. But testing one modem in one OS and then a whole new one in another OS really doesn't tell you anything on why your troubleshooting your speed with two different modems with two different OS's. If it was one modem on one machine, working under two different OS's, and this occured, then I would try to tweak the modem then.
Its like my cable modem in Linux gets downloads at an average of 800kbps, and under Windows(tweaked)only an average of 150Kbps to 300Kbps.

Gotcha.

My bad. Working on 2 hours sleep.



Should be "before you go out and buy a new modem".

Is it a PCI modem (as opposed to ISA)? If so, then chances are excellent that it's a WinModem. http://www.linmodems.org has Linux drivers for many WinModems.

Smile Thank you all very much!

Hey, I want thank you all very much for your very helpful comments and suggestions for my modem speed problem! I very greatly and sincerely appreciate your help.

It turns out the solution to my problem was indeed found at the linuxnewbie.org link that billsabub passed along to me. [Thank you!!!] That was exactly the "modem tweak" (at the software level) I was looking for.

As an indication of how effective this tweak was in my case, I just measured a 50% increase in my modem speed using the computingcentral.msn.com speed test that trickykid forwarded to me some time ago. [Thank you, too!] (And that was simply using the initial parameters suggested in the help article. I have not yet even fine-tuned my system.)

So, I really want to thank you guys again. You really helped me solve a critical problem that has been vexing me for some time now.

Thanks so much for your help!
Ben

Quite welcome!

And if you have a burning modem, I think there are shots for that now.
