Hi, I noticed that you've enabled Drop-in gateway on Brume 2. In v4.7, VPN policies only apply to client devices on the drop-in gateway router. To configure VPN policies for clients on the main router, I suggest to upgrading to v4.8 and try it again.

I upgraded to 4.8.2 beta which actually works nice. The cellular problem still persists.

Unacceptable.

Brume 2's USB port has connected to multiple USB devices. please try connecting only the M2 board to the Brume 2 and then see if the problem persists.

I tried this already but nothing changes. I also upgraded to Firmware 4.8.2 Beta which is nice but does not resolve the problem at all. Even worse now mit Network storage is no longer accessible though nothing has changed. I am pissed and have no more patience. I paid a lot of money and all I get is unfinished Nerd stuff that doesn’t work as supposed. I hereby claim warranty and ask you to exchange the whole GL-M2 Board immediately .
