Modem Issues To Haunt You In Your Sleep

Posted 03 April 2003 - 02:58 PM

Here's something for you all to toss around a bit. In 8 years of building and repairing PCs, Ive yet to come across anything like this.

Ive got a ampton mobo that came with a pctel hsp56mr AMR high riser modem. Ive used thus under windows ME, and windos XP pro without a problem. Recently I upgraded to a shotgun account with my ISP, which is a dual modem, dual phone line account. I added another modem, both connect at 50k ,so my overall connection was 100k, as it was supposed to be. All is good.

I started having some major issues with my OS, that I couldnt track down, and decided the fastest and easiest way to fix was to do a fresh instal. I keep a copy of the newest drivers I have downloaded so that I will have them in cases like this. I back those up to a network drive, and proceede to format.

I get everythign re-installed, and I try to connect to the net. My HSP modem wont connect faster than 28k. So I go about the normal procedures, checking drivers etc. Nothing can and will fix it. Im using the EXACT same hardware configuration and the EXACTsame driver version as I was before. NOTHING has changed in that area, yet it refuses to connect faster than 28k now.

Ive checked the lines with other modems, no problem. Its just that one modem. I even tried two different INIT strings to force it to connect at 52k, and it still wouldnt.

Any suggestions?

Hi Juravieal,

Did you back up the registry from the old machine? Maybe something in there didn't quite carry over. That's all I can think of offhand.

perhaps you were getting false readings before? perhaps with the new install it is actually showing you the correct connect speeds? have you tried taking out the "working" modem and just trying a single modem connect? i know you've switched wires, but i'd like to know if you took the other modem completely out of the system yet and tried it. is the "shotgun" connection a multi-linkPPP? if it is the secondary modem would connect slower as upstream speeds are capped at 33.6kbps anyway.... so a 28.8kbps connection is completely believable.

Yes, I removed the each modem individually and tried a single line connect with both of them. The working modem connects at 48k by itself, as it does with both modems. The "broken" modem still only connects at 28k, even by itself. Before the format, both were connecting individually at 48-52k, as they are supposed to. Now the hsp modem, will only connect at 28k, even if it is the only modem in the system.

Ive not checked the registry, as it is on the same system, I just did a complete re-partition.

It is "possible" that it was a false reading before, or that it is a false reading now, But since nothing has changed Im curious as to why it is displayed differently. Upon more testing, my actual download speed doesnt seem to be noticably different when using both modems, though it is very much slower using JUST the one connecting at 28k. Im still curious as to what happened.

*UPDATE*

I got tired of screwing with it, and went out and bought a new USR, model 5699B. Pulled the "problem" modem, set up the new one, connected with my OTHER line, updated the drivers for the new one, and redialed with just the new modem. Still wont connect faster than 32k. The other modem connects at full speed by itself without a problem. wtf is going on here?

I installed the same model modem in an Emachines (blech) running WinME (double blech) of my mother in laws, and it works fine.

sounds like when something goes wrong with a car...never ever screws up when u take it somewhere else to examine...but when you're alone with it...it knows it automatically tries to kill itself...at least in my case.

aside from the odd analogies...i have no frikkin clue...i upgraded to cable, and life has been a breeze...'cept when a big storm roles around and kills the power and cable...then my computer just sits there yelling at me that i'm running off of my USB and that my network connection is kaput...

sorry bro :\

Hmm, I put another update in here, but I dont know where it went. Anway, i spent an hour and a half on the phone with a tech going over everytyhing it possibly could be. Nothing. So I set up my grandmothers dial up account, for a different ISP on here, and dialed it up with the same modem. Connects full speed. Tried the same modem with my ISP. 28k. Basically, its on their end, for sure 100%. Also, its only my local dial in number, as I tried a long distance number for my ISP, and it connected full speed.

Also, it was mentioned that it was probably my "upstream" modem, and that that speed is normal. I just wanted to point out that this is a common misconception when it comes to multi-link connections. They do NOT count one modem and upstream, and one modem as downstream. I even talked to my ISP engineer to be sure of this. It simply dials both lines in, bundles them together, and acts as one big modem, as opposed to two "small" ones.
