We have a CISCO871-SEC-K9 and need the optional WLAN 802.11b/g. I cannot find any description or picture or part number.
Can anyone give me a hint where I can find this information on the Cisco web site?
Thank you, Ed Podowski

Q. Is it possible to upgrade a nonwireless model to support wireless?
A. No, a nonwireless model can never be upgraded to support wireless. The Cisco 870 Series and Cisco 850 Series have two separate versions, a wireless model and a nonwireless model.
From this doc;
Hope this helps, sorry man!
