Re: Sudden slow speeds. Need Assistance

Did you also fill in the Subnet Mask plus the Default Gateway values and what did you use?

The ZyXEL P645M-11 uses a crossover cable which is supplied in the EL Modem box.

If you used an XP or Vista PC did you disable the built in Firewall to allow Telnet to work?

If your Motherboard has a Nforce chipset, did you disable its Firewall to open up Telnet access?

What’s the point of owning a supercar if you can’t scare yourself stupid from time to time?

I used the cross over cable. I ran the Windows hyper terminal software and entered the address 192.168.1.1, but was not asked for the subnet mask or gateway. I did not disable the Tiny firewall software. I got Earthlink to open a trouble ticket with Covad. I hope that they can get to the bottom of this. Thanks for your assistance.

Are you sure you have the P645M-11 Bridge Modem and not the P645-UHP Modem? What does it say on the Label on the bottom of the ZyXEL Modem?

Go to Menu 24.8 ("Command Interpreter Mode"). Here's the commands to completely snapshot your connection:

w a l n (short for "wan adsl linedata near")
w a l f (short for "wan adsl linedata far")
w a c (short for "wan adsl chandata")
w a p (short for "wan adsl perfdata")

The password "mspzyx" may have been short-lived as is access via telnet.

Upgrading firmware has risk (there's no easily available serial port to fall back on, you better know your settings, Earthlink no longer supports the modem, etc.) There's also a few ways to do it - Menu 24.7.1 is a key.
