Hi,
I have big problems with such routers ( I have 24 ). I use them to for communication of ATM devices.
The problem is that the router hangs if there is some changes in GSM provider network and it needs hardware restart.

Also when I make experiments, I found that the router cannot boot if you remove the antena cable.

I tryed everything update modem firmware, tryed different IOS version, upgade also rommon monitor, but no success.

If you can help

Hi David

I have the same setup as yours except my SIM card is a post paid account that doesn’t require authentication.

Do you know how to configure the profile for the above SIM?

What I am getting is:

Profile Information
====================
Profile 1 = INACTIVE*
——–
PDP Type = IPv4
Access Point Name (APN) = telstra.internet
Authentication = None
Username: , Password:

* – Default profile

Thank you.

The CISCO881G-A-K9 is the sku for North America, however, the modem that comes with this bundle is PCEX-3G-HSPA-A, which is an AT&T only modem and will not work with Canadian carriers, is there a way to adjust the modem to work with other carriers ?

Does the 881G provide wireless access out of the box or is that an extra? I have 1 here and when using the Cisco CP application I get “no wireless interface installed on this router”
