RE: [WIRELESS-LAN] Cisco AIR-CAP2702E could not discover WLC
Hi, We’ve had an issue with AIR-CAP2702I’s doing this, the issue was they were presenting 2 MAC addresses, the one on the sticker, and the next on in the sequence; it’s this next in sequence which was requesting DHCP. We had to register two MACs for each AP for DHCP. Once the AP has updated its image from the controller it reverts back to using the MAC on the label and everything is as should be. TBH it pretty annoying, we’ve had around 200 out of 400 units do this. Whether this is your issue I’m unsure, but it’s worth checking; also make sure your switch ports are configured up to accept multiple MACs. Cheers, Jezz.

RE: [WIRELESS-LAN] Disabling 802.11b speeds
It can't, but can be connected to a PSK network. We found that in certain halls and other high density use areas we had very high channel utilisation with 1 2mbs enabled, so disabling the them might have upset a couple of Wii's (literally a couple) but it's a small price to pay, channel utilisation dropped from 90%+ to around 50% when these speeds were disabled. It would be nice to be able disable the other 11b speeds (and possibly 6mbs) if it was safe to do so with upsetting fussy devices. Jezz.

Do you disable any of the other 802.11b rates as well? I turned off all of the B rates a few years ago but then quickly learned about the Wii issue. While I like the solution of keeping the b rates off and telling the wii users to use an ethernet cable, we have a few locations where students live that are wireless only, so that option doesn't work for us. I ended up relenting and turning the B rates back on to make the Wii users happy. Reading this conversation I'm thinking about taking another shot at disabling some of the slower rates, but leaving 2Mbps for the Wii people.

A side note, disabling 1mbs stop Nintendo Wii consoles from associating. Is anyone aware of any other device that is known to suffer when disabling any of the faster speeds? I have Kindle in my mind for some reason when disabling 6mbs. Cheers, Jezz.

We have not had any users on 'b' in the last 6 months and are confident about turning it off. One question I do have for those of you that use Cisco controllers, is how are you turning 'b' off? I talked to a network consultant and they said to go into each WLAN and set the Radio Policy option to 802.11a/g Only and that would take care of it. It looks like most in this thread change the data rates to disabled under Wireless 802.11b/g/n Network. I am curious to know which method is better and what your settings look like. We are running code line 7.0 but will be upgrading to 7.2 soon if that makes a difference.
