yes, you must change the default frame size on the ethernet side of both bridges to 1522 (default 1518). As far as the radio is concern it will pass the frames out over the wireless. You will need a switch on the other end of the bridge to recieve the frames and break out the vlans.

Actually, 802.1q adds four bytes, ISL encapsulation makes the frame much larger (by 30 bytes) I so the increase from 1518 to 1522 would make sense for dot1q and an increase from 1518 to 1548 would be needed for ISL (if it's even supported on the 802.11 stuff, but I can't speak on that).

An ISL frame can be as big as 1518 + 30 = 1548 bytes. The original frame is encapsulated in a 26-byte header and a 4-byte CRC. An 802.1Q frame can be as big as 1522 bytes. 802.1Q inserts a 4-byte header immediately the destination and source MAC addresses (and source-routing information, if
