This should be a refurbished unit. If it's fixed, they must have forgotten to test it before calling it fixed. With the latest firmware installed, the 5G band started to crash, and then a few hours later everything hung. Factory reset and try again. The router's response during setup was very slow, so I suspected the problem was still there. After completing the configuration and restarting the router, it was not possible to connect to the 5G band. Back to Revan.
