Hi All,
Here's a strange one for you...
I have a Linux box with a PCMCIA adapter PCI card in it. Plugged into said card is a cellular modem card.
I can configure wvdial and dial the modem card perfectly. My ppp0 interface comes up and I can ping everything.
I also have a network card on the motherboard. Once again, by itself the network card works correctly. That is with the modem NOT dialed up.
Here's where things get interesting...
If I flush the firewall rules: iptables -F Bring down the eth0 interface: ifconfig eth0 down Connect with the modem: wvdial & Bring up the interface: ifconfig eth0 192.168.7.1
At this point the ppp0 interface drops off and redials. It is no longer able to maintain a stable connection. ppp0 and eth0 do not use the same IP range.
Thoughts?
Shawn

Maybe IRQ-conflicts? A long-shot but look into the hwconfig and see if there's something fishy.
