I have nine MR34s and one MR18 AP with several NAT SSIDs and one Bridge SSID. On the MR18, some clients are unable to connect to the Bridge SSID, or if they do, there's an apparent IP issue which won't allow them to get internet or connect to other network resources.
Unfortunately, I'm unable to replicate the problem at this time. No errors in Wireless Health for the client who's been having trouble lately. I'll double check the VLAN. It's a very inconsistent and seemingly random issue isolated to that one AP and SSID.
