Is There One... Just One Modem That Will Work With Xp ???

i'VE HAD NOTHING BUT PROBLEMS WITH XP AND MODEMS. ON THE LAST 15/20 OR SO MACHINES I'VE BUILT WITH XP IVE EXPERIENCED INTERMITTANT OR UTTERELY DEHABILITATING MODEM PROBLEMS.. SORRY DID I JUST SAY THAT??.

Anyway ive tried maybe 10 different modems with difefrent chipsets and still the same old problems.. no dial tone/ unable to establish connection/ frequently dropping off line.. etc etc.

Is anyone else having the same issues???

oh.. i have tried updating drivers.. changing com ports... checked passwords and user names,cables have been swapped,modems have been tested... no irq hardware conflicts..


any ideas as to what the problem could be...

Are these all winmodems?

no.. why?

Did you check for any powermanagement in the device properties... little check boxes like, allow windows to control....

I haven't had any issues with the modems I have put in... but then I installed the os with them fitted already.

list off some of the modems and the motherboards you have tried them with for us please.

Never had any issues with 3com/usr modems (unless it is a winmodem) pci based modems under xp.

Depending what boards they are being used on, they might work better on another pci slot.

Maybe there is an issue with the ISP provider.
Like call waiting or a different phone #
What about just test dialing to your fax line???

Are you trying to dial out on a digital phone line???

Must be an analog line.


Please let us know what boards and modems you are having issues with??

Upgrade to Win2K:D

yes win 2k has my thumbs up.. (no problems with modems)but im still impressed with xp...service pack has sorted out a few niblles and with a quick change of gui to the 2000 classic it runs looks and feels even better in my opinion.


I have disabled power saving features for the modems and have tried re anabling them but problem stays the same.

i have updated each machine in turn with service pack 1 and still ther problem remains.

I have tried moving the pci modems to different slots... reset the relevant bios settings and re installed drivers.. still same problem.

I tried have tried changing the com ports.. no change

drivers have been updated where possible and xp's own have also been tried.

diamond's xp support seems rather lacking for a lot of its range, so beta drivers had to be tried.

None of the phone lines are digital.. no switching units.

ISP's (pnhone number, user name and password transferred) connection is stable and functional on machines with 2k. no dropping off line.. unless of course the time limit is reached

some of the modems will run fine on some machines with xp and then not at all or intermitantly on others.
All though have been tested and seen running properlly on win 2k based machines.

i will try to list some of the modems i have tried and had problems with xp.

SCAN Modem PCI 56K/v.90 Internal (Rockwell)

Diamond PCI Pro Modem Hardware 56K/V92

diamond external usb modem.

several with conexant/lucient chipsets.

couple of sofware modems one was made by diamond(yes another one.. only bought it about 4 months ago??) the others im not sure of.

load of external serial modems.. no names.

some of the motherboards in question : epox 8kha+, asus a7n266vm.

I have updated the bios's and also reverted to defaults... also updated chipset/controlelr drivers

I do know that if an external modem is powered off when the machine is booted - XP will not be able to use it. I haven't had time to find out why, but it will be something to do with setting the network connections before it gets to the desktop.


As to internal ones, that would be a driver issue.

i always turn them on before booting..

so far I havn't had any problems with USR, Comstar, GVC and anything made by Pine

as a rule i try to stay away from Diamond modems, i've had nothing but trouble with those things, and thats under XP, 98, 2000 you name it. but i haven't had any problems with any modem other than a Diamond under XP.

Generally I haven't had any problems with any modems and WINXP until this week. Almost everyone uses Cable or ADSL in these parts.
Looking for help on this problem though.

I have shipped two identical systems, one a few weeks ago and one just the other day. These are home PC's and are in different homes. When the computer is on the modems work just fine and so do the phones in the house. When the computer is off the phone service in the house dies. No dialtone on any phone in the house and the incoming calls get a busy signal. The one I shipped the other day exhibited the same behaviour in my shop before it left but I didn't think anything of it at the time (thought it was just one of those temporary phone glitches ya know)

Systems are Shuttle MS52N mainboard, Cel 1.7, WD 20HD, 256 DDR, Smartlink (Archtek) 5634PCW Intel modem.

We went to one site today to try a different modem (USR Vader) and the system wouldn't even boot with it in it.

Anyone know whats going on?

Thanks in advance.

Is the modem plugged into its own telco socket, or via a doubler adapter?

Have you tried an external modem?

Have you tried a new cable between the modem and telco jack?

Is the machine actually off or just in standby mode?

Does it exhibit the same behaviour if the power cord to the computer is removed?

I don't mean to sound silly but are you using an analog phone line? Many office phone lines are digital or use signaling proprietary to your PBX.

Also, I've blown a couple modems out connecting them to the last PBX we had.

You might also check to see if "wake on modem" is active in the bios

for the lucent modems check the ATI3 in diagnostics, if it's 5.98A your gonna get trouble, you will need to update to above 6.00 at least (for XP, 2K not effected) and last time I checked the newest was 8.22

I've used Creative PCI winmodems with no trouble at all on XP and I've used Diamond external serial modems with astonishing results. Can't think of any that I've had problems with specifically.

Hi all. Just to followup on my problem I posted on from a couple weeks back regarding the modem cutting off the phone service when the computer was off. Must of been a bad batch of modems. We've replaced them with other modems of the same brand and all is OK.

Thanks
