Hi @AxL1971, @Networking101, There was a bug in MR 30.7 where client balancing was rejecting clients from connecting to particular SSIDs. This is resolved in MR 30.7.1+ firmware versions, and we didn't have reiterations of this bug. With this said, it is still recommended to keep Client Balancing disabled due to often client compatibility issues. If client doesn't support 802.11k, you can see something like "client was rejected by the AP" or "reason.code == 17" in the logs, which doesn't necessarily mean that that the AP is malfunctioning, but can just be compatibility issue. This behavior is explained quite well in this KB.
