Cisco 881G with Verizon 3G - Cannot get the 3G to work

ddrummer68 · ‎09-21-2012

I've been asked to configure an 881 with a Verizon 3G backup connection as a backup to the FE4 primary WAN connection. I've been unable to get any connectivity through 3G, and in most cases, as soon as I try to configure 3G, I lose connectivity through FE4.

Currently, I don't even have FE4 connected; I'm just trying to get the 3G connection working, so then I can take it back to the office and have a functional 3G backup connection. If anyone can point me in the right direction, I'd sure appreciate it.

Here's the running-config, along with the output of some show cellular commands.

Thanks a lot for looking at this question. - Bobby

Just noticed this posting, the first thing I noticed is where you placed the dialer chat script, should look something like this:

chat-script gsm "" "ATDT*98*1#" TIMEOUT 60 "CONNECT"

interface Cellular0

dialer string gsm

line 3

exec-timeout 0 0

script dialer gsm

(not under console port)
