Re: unable to connect with internal modem under Ubuntu

Jacques and Antonio,

Thank you for bearing with me. 

Antonio, I made the edits to the resolv.conf file and re-enabled "Stupid mode = yes". 

Jacques, my attempts to connect via the Network Manager in Ubuntu were unsuccessful.  Nothing happens when I click on "Connect to ppp0 via Modem".  I know it's trying to do something, because if I try wvdial after clicking on "connect to ppp0 via modem" without disconnecting via the Network Manager, wvdial will show the connection is busy. 

I followed your directions for creating the dump.txt file while wvdial is running.  Here is the contents of that file:

The "Belkin" probably refers to the router I have for my cable connection.  Several days ago, I had the Ubuntu box connected to the cable internet, but it has been physically disconnected in all the time since (during the whole period I've tried to connect via the modem). 

Thank you both for your help!

Devon
