The recent firmware update for the RE505x V2 appears to be broken. After updating to the new firmware no devices could connect - so no app or web page login possible - to the extender and a factory reset was needed. After configuring the extender after the factory reset and client devices able to connect again if the extender is power cycled no client devices can subsequently connect. The SSID is visible but a connection is never achieved - this is for all previously connected devices - just forever cycling attempting to connect. The extender is configured 5gz to router connection, 2.4g extended network only. I can see from the router the extender is connected over 5g but the 2.4g of the extender is visible but never accepts a connection. Only a factory reset of the extender resolves it until it is power cycled and the problem returns.
