FLEXCONNECT CLIENTS CANNOT PING WIRELESS CLIENTS AFTER UPGRADE TO 8.0.121

Hi,

I'm having issues on our flexconnect AP's wherein wireless clients cannot ping each other. I already checked the p2p settings on the wlan and it is disabled. These clients can ping their gateway ip's. Our branches have a flat network with a Router on stick setup. Wireless clients on our branches can successfully access resources in our HO. We are using same ssid with HO and BO. PLease see below SAmple output of a flexconnect client

I don't know where the decision to upgrade to 8.0.121.0 came from but Cisco has removed all links to download this particular version due stability issue.  Upgrade to 8.0.133.0 and see if the problem sorts itself out.

We upgraded to 8.0.121 from 7.4.121 to support our new AP's (1700)
