I recently replaced wireless at a site from the internal AP on an 877-WM with a (standalone) 1262 running 15.2(2)JB. I've configured the AP pretty much the same as I always do for Cisco AP's for single SSID operation (single bridge domain, BVI1 also management), and things seem to work.
However on my laptop I have VMware running, and a guest with NIC set to bridged mode is unable to DHCP, however IPv6 works fine.
When searching for this problem I see a reference to a "ip-mac-binding disable" command on WLC setups, but can't find if that maps to a setting on a single AP.
The relevant part of the AP's configuration is:
dot11 ssid # Removed
authentication open
authentication key-management wpa
guest-mode
mbssid guest-mode
wpa-psk ascii # Removed

bridge irb

I had the same problem and found a solution: enable DHCP relay agent on the AP and it works. Replace x.x.x.x with the IP address from your DHCP server (typically the Internet router located on the same network / broadcast domain.
