Hi, can I check why message " 2.4Ghz and 5Ghz Configuration Mismatch" existing in performance observation dashboard. But I checked my router and AP both are aligned with similar channel and bandwidth.
Some other aspects of configuration that could be different include things like the basic rate and supported MCS indices. If your APs are different models, or are running different firmware versions, those default settings may be different. Depending upon the model of AP, they may or may not be configurable. As a general rule, it is not necessary, and usually inadvisable, to the same channel when you have multiple APs.
