@azvicki Plug the extender into a power outlet and then press in the reset button until the lights cycle on it. Should be back at factory presets.

@Router_Review Better off opening up a tech support live chat session to ask about beta firmware. Also its a weekend so you won't get anything official on here.

@NyteFalll Since you got it from the ISP, it would be best to ask them about how it is set up. Knowing them they probably have stuff disabled.

@PlayerOne check out their response: TP-Link - Our Security Commitment

@NyteFalll Double check that the 10 GB port is not a WAN port, that is usually how these routers are set up. LAN ports will say LAN next to them and the WAN port will say WAN or Internet.

@WKMAN One thing to remember is that the BE900 is not wifi 7 certified yet, so expect more firmware updates for it while they finalize the certification. Its a newer product so expect some bugs.
