881 Router Wireless Module

[Christopher Kofon]

Hi Everyone,

I was given an 881 router to work on. I was told that it has the integrated wireless module installed, but I cannot see any radio antenna on the device. Is there a command I can run to determine if the wireless module is installed. I tried sh ver and it did not reveal any information to suggest there is a wireless module.

Also in global configuration mode, the command interface Wlan-ap0, is not accepted.

Any help is appreciated. Thanks.

880W antenna is fixed.  You can't remove or replace it.  So if there's no antenna then it doesn't have one. 

The command "sh inventory" that Michael has posted is a pretty good indication as to the exact model of the router you've got.  "sh version | b License UDI" command will also help.
