Hey all,

I am trying to configure a new cisco 851w router for a small business. I am experiencing an issue where the wireless users on the same Vlan, Bridge, and SSID are not able to ping other wireless hosts. I have seen other people with this issue after searching google but have yet to see a resolution.

I have the config highlighted at pastebin:

If anyone can lead me in the right direction it would be greatly appreciated.

Still no luck...

Also, wireless and lan computers can ping without issue, not sure that helps.

I've tried setting and unsetting the bridge-group 1 port-protected (PSPF) but that doesn't appear to help.

Found this solution on my own.  Fortunately I had a second Cisco 851w router to work with.  Basically, it appeared to be an issue with the hardware version and IOS version.  Config did not change, but worked on the second device.  I changed the IOS version on the original device and it started working as well.
