Problem: Your V.92 modem does not connect reliably at V.92.
Solution: First be sure that you have the latest modem firmware
downloaded from our Web site, as discussed on page 7.
Also make sure that your ISP offers V.92 at the number
you are calling.
If you still have a V.92 problem, you may want to modify
your Internet Connection string in Windows: On your
desktop, double-click the My Computer icon, and then
double-click Dial-up Networking. Right-click the existing
Internet Connection that you wish to modify and select
Properties. Click General | Configure | Connection |
Advanced.
You can add initialization (init) strings on the line labeled
Extra Settings. Enter one of the init strings listed below.
Try these commands one at a time until you find the one
that gives you the highest possible connection rate for
your telephone line conditions.
