My last request for help from this list a couple of weeks ago ended with the conclusion that my internal modem was not able to work with Linux (the machine runs Ubuntu 8.04). So I bought an external USB modem that is advertised as Linux compatible (the USR 5637 -- see http://www.usr.com/support/product-template.asp?prod=5637). When I plugged the modem in at first it was not recognized. I searched around on the web and found some instructions that were useful (http://www.linuxquestions.org/questions/dreamlinux-82/dell-1535-ubundu-modem-disaster-690995/). I followed the instructions, and was able to get the modem to be recognized by wvdial (I edited the Ubuntu desktop network manager to include the dev/ttyACM0 modem as well). The modem seems to connect with wvdial, but I'm not able to browse web pages in Firefox (browse active online sites). The modem's power and data lights are on when the modem communicates with the ISP. Here is the output from wvdial: $ sudo wvdial --> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ ATZ OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Modem initialized. --> Sending: ATDT4951000 --> Waiting for carrier.

I've tried this many times from wvdial with the same result (even after rebooting), and I've also tried to connect with the Ubuntu network manager, but it shows no visible sign of connection (network manager icon shows no connection and Firefox is unable to connect with web sites). Do any of you have an idea what might be the problem? What other information do you need to help diagnose the problem? Thank you yet again for your help! Devon
