For no apparent reason the rc7 will change all client mac’s connected to ap to xx:xx:xx:xx:xx:xx and no access to any of them work. This only happens with rc7. BTW this is a server level 6 routerOS.
I have seen this occur exactly one time, also…
Well I even tried reinstalling it before I determined it was a bug. Reinstall did not fix so it wasn’t a corrupt installation. Secondly after a reboot sometimes the mac’s showed up fine from anywheres from a few minutes to a few hours than nobody would have access and the registration table showed everyone as all x’s again.
