Re: usb modem connect/auto-disconnect problem

Reid,


In your wvdial.conf I read

Modem = /dev/ttyACM0
/dev/ttyASM0 is a Unix device name which has been assigned by the modem driver.

Almost certainly, gnome ppp has not detected the presence of this device as a modem.

Thus almost certainly this simple command given as superuser (using sudo with Ubuntu or su with other Linux distributions) will make the modem known to gnome ppp:

ln -s /dev/ttyACM0 /dev/modem

Next, your "not able to get firefox running" is too terse to help you.
Do you mean that you cannot START (launch) firefox or that you cannot surf once you have a modem connection with wvdial ?
If you can start Firefox but cannot surf then try to open www.google.com (will not open)
then try to open  209.85.135.104
If the latter begins to work, read item # 14 in http://linmodems.technion.ac.il/FAQ.html

Can dial out with wvdial from terminal but from apps> internet> gnome ppp does not work. Is there a connection that has to be made between wvdial and gnome ppp that I am missing? Not able to get firefox running, it is installed. Can firefox run from the terminal and if so how? Disconnects and reconnects approx. every 30 seconds. Thankful for any help Reid
