Problems Connecting with USR v92 Modem
Posted by Clarke M on 28 March 2006 06:17 PM
A few of our customers have reported that they cannot connect (or are getting frequent disconnects) when using a new USRv.92 modem.

If you are positive that you have a USR v.92, here is what you can do:

Windows 95/98/ME

- Click START and select SETTINGS and CONTROL PANEL
- Double-click MODEMS (or Phone and Modem Options in WinME)
- Click on PROPERTIES
- Click the CONNECTION tab
- Click ADVANCED
- In the 'extra settings' box, enter the following: +PIG=1 +PMH=1 +PQC=3
- Click OK
- Click OK again, and then close.

Windows XP

- Click START then CONTROL PANEL
- Double-click on MODEMS (or if the control panel is categorised, you'll find this under Printers and Other Hardware)
- Click on the MODEMS tab
- Click on PROPERTIES
- Click on ADVANCED
- In the 'extra settings' box, enter the following: AT +PIG=1 +PMH=1 +PQC=3
- Click OK
- Click OK again, and then close.

The reason for this is that the v.92 protocol is quite new, and not many ISPs (including us) have upgraded to it as of yet. Customers with a v.92 modem will notice that their connection may suffer due to the mismatched protocols. By entering this initialization string, it will force the modem to work as a v.90 modem, and your connection will be much more stable.

If this string does not do the trick, please contact Support - we may have a better string for your particular modem model.
