int dot11radio1, chosing least congested

[jason.aarons]

1) Do the 1120 by default search for the least congested channel and stick with that?

2) In a large complex, wireless network are there any advantages to using least congested? ie multiple floors, lots of overlays, rogue aps, etc. By hardcoding the channel I know something else will come up on the same chanel. I think my problem is the customer installed too many radios in too small an area. How can overcome having to hardcode the channel?

I called Cisco TAC, the SE suggested leaving least-congested might be a bad idea. A scenario would be "kid on skate board rides by, and AP-A changes channels, the AP-B nearby reacts to that, then AP-C see detects interference from what AP-C did so it changes frequencies, and this mushrooms on. Then another person sets up a rogue AP which causes another ripple effect". This is like spanning-tree, don't guess what channels are where, or where your root bridge is at today (advice, hardcode the channel in your APs and the root bridge in your Catalysts)

u can decrease the power of the radios if your radios are to too close to each other. Also if the cards are of cisco an option in ACU "scan for better access points" ca be disabled. This ensures that the client dont roam very fast among APs
