I think we're arguing over semantics; what's important here is that the STA tells the AP to buffer frames while we're performing a scan, correct? > If you wait until the end of the scan to return to the bss channel then > you potentially miss buffered mcast frames.

This is particularly relevant for APs that have a DTIM interval of 1 -- if you're doing a passive scan, the dwell time on that other channel (you need at least one beacon interval) could cause you to miss bufferend MCAST frames. In all fairness I don't think I've seen any implementations that handle this cleanly. - Solomon -- Solomon Peachy ICQ: 1318344 Melbourne, FL Quidquid latine dictum sit, altum viditur.
