the 3com router has a flashing sync light. my wired modem works fine but when i run the diagnostics to getthe line stats it tell me that it cant connect to the internet, possibly because of a firewall or proxy server. i've disabled the only firewall that i have etc etc and still can't get the diagnostics to run.

Then, probably, methinks, you have 2 separate issues. 1] you might have a broken router 2] you have a some kind of a pc setup problem with your modem. Don't forget, when you cahnge from ethernet to modem, you are using a different network interface, for which any firewall amy be differently setup.

Depends now what you want to do. Do you want to change to using the modem? Or do you want to fix or replace the router - ie the modem is just for diagnostics while you fix the router? If it is the latter, it might not be worth the fight with the modem.

And how are you accessing the internet now? Are you on dialup on the same pc?

My question about the firewall was in regard to DrSpeedtouch seemingly being unable to access the internet
Try resetting the router, usually by depressing a recessed push switch for a few seconds and upon reboot, enter your logon etc information and tell us if it will sync now.

I see this is a few months old, but I try a reply anyway as I have exactly the same issue even down to dr.speedtouch not getting through. My routers (I have a netgear in addition to the 3Com) worked fine for about a week (so the settings should be ok) and after that the only way I can get stable contact with the net is with the Speedtouch modem (I have had a few minutes now and then through the router). I have also disabled firewalls when trying dr.speedtouch but it still doesn't work.

Have you found out more after this thread ended?
