|Forums | Conexant (Public) | Trouble with Wake on Ring (WOR) - my fax modem does not always wake the PC||Watch|
|Posted - 12/5/2009 11:06:33 AM |
When my WinXPPro SP3 machine is in sleep/standby/suspend mode (S1 or S3), the fax modem wakes the machine some of the time but not all of the time. I want it to wake the PC every time, with 100% reliability. (When the PC is up and running, the modem and the machine receive faxes beautifully.)
What do you suggest?
Modem: Conexant D850 PCI V.92 Modem with recent driver update to version 18.104.22.168 (7/3/2007) (but this problem is the same now as before with the 2004 driver version)
I've tried everything, including upgrading BIOS (now to A15), re-checking all the Wake options in BIOS, trying two different sets of drivers for the modem card, running system file checker (sfc) a number of times, trying both S1 and S3 for sleep, uninstalling and reinstalling the windows fax service (fxssvc.exe), re-checking the Power Management tabs in Properties for the modem to make sure it is set to wake the PC, trying various combinations in Power Management for the whole PC, trying the powercfg settings described below, and maybe a few other things I've forgotten.
But, alas, my Wake on Ring is still 50% UNreliable when the PC is in Sleep mode, and I've tried it again with both S1 and S3 sleep.
Also - Even after running certain DOS commands (see below), my Wake on Ring is STILL unreliable and intermittent.
The commands I have been running are:
powercfg /devicequery wake_armed -- to confirm my Conexant modem card was listed, which it is, and to get its precise name,then:
powercfg /g on /option wakeonring
There's no pattern at all as to when WOR will work and when it won't.
Do you have any idea why WOR doesn't work half the time? Is there a particular i386 file I should try to reinstall?
As to the Registry, per a post elsewhere by Georgio:
I have found some of the registry keys Georgio described for my Ethernet NIC, but not for the fax modem having the WOR problem:
There are no PnPCapabilities in the registry keys for my Conexant fax modem. (It's only the Conexant modem that has a problem with Waking.)
The registry key for the Conexant modem is
What do they do? Should I turn one or both of them off?
There is another subkey "WOR - REG_BINARY - [long binary string with 0's and f's]"
Any clues here? The modem is still VERY erratic for Wake on Ring when the PC is in standby.
