1941W bridge issues

Unanswered Question
Aug 5th, 2010

I'm trying to setup a (what I think to be) simple wireless network using a Cisco 1941W integrated services router. Currently running this on a test environment behind a little Linksys router/modem combo (at 192.168.0.1). I would like to use the 2.4ghz radio as a root access point for clients to gain access to both the wired network (currently at 192.168.2.0) and the external network (currently at 192.168.0.1). Wireless clients are set to 192.168.1.X.

I can ping external IPs from the router (ie google.com), ping all the interfaces on the AP (BVI interface and clients). From the AP I can ping all the interfaces on the router, I can't however leave the router at all (ie ping 192.168.0.1, google). Been playing with this for a while so there might be some extras in my config but:

Hi Jeff,

I don't see a default gateway configured  on the ap.

looks like it should be 192.168.1.1
