I've installed two T750SE AP's, one AP is configured correctly but the other one gets a102 error "configuration update failed" when moving this AP into a AP group and/or changing it's AP name.
The correct configured one is configured in the same AP group and they're both running the same firmware version 22.214.171.124.301 (also checked through SSH on the specific AP).
The faulty AP is and stays online in it's default state so it seems....
Somebody have any suggestions???
