First drawback to Fritz box, it is a pure router without modem. This must be clear to everyone.
Had so bad if the routing of the LAN / WLAN to WAN (where the modem / Internet depends) would also work.
Despite Fi Internet connection is not there. Constantly! A Reconnect the WLAN and suddenly it goes again.
Then the 5GHz Wi-Fi throughout is worse than the 2.4GHz. That should be the other way around. Especially as the 2.4GHz and is even worse than it was with the Fritz box. Right next to the router you are but sau quickly in the WLAN when the running because times.
All the nice settings that you can do are great. Had a great device if the basic functions of a router to route namely, would also go.
I pack it in and send it back. If ne stable firmware is there, you can do it so try again.
