If you're gonna run WDS, you need to drop down to 12.3.2 (JA) on the WDS dedicated WAPs ... Cisco thought it got fixed in 12.3.7 (JA1), but it didn't. Otherwise, our two WDS dedicated WAPS (radios turned off) for 59 other AP's only lasted about 24 hrs.

Thanks for the email. We do have AirMagnet Surveyor
software as well as WLSE. You mentioned about the
memory leak issue. How long did the APs stay up on
12.3.4.
Thanks.
