Having some issues with a possible broken radio (issue might be widespread, so I'm trying to diagnosis, rather than just replace). Anyways, our site has about 20 APs. We deployed two APs right next to each other. AP1 doesn't have any users on it, while AP2 has quite a few. Anyways, if I remove AP2, I expect users to roam over to AP1, but that never happens (APs are provisioned identically.. same model as well). Looking at things historically, I haven't seen a single user connect on the A radio since July. Oddly enough, when I do a "show ap arm state ap-name <ap-name> dot11a" on any of the surrounding APs, the suspected broken AP never shows up. Is this definitive proof that the AP's radio is broken? Is there anything else I can do? Unfortunately I haven't been geting much traction with aruba TAC.. figured I'd give this a stab and see if any one has any ideas.
