2.4ghz for the frequency
Not all clients are doing the re-reg. As for spectrum analyzer, the AP can't do it, and to an SM is going to see a huge amount of signal right where the AP is, because it sees the AP, so I wouldn't be able to see much else.
I attached the signal to rereg table I made. It goes, AP Sig, Client Sig, Rereg, Client Uptime (This was after the AP was up for ~12hours)
