Thank you!
I did several hard resets and got it setup now the way it used to (sort of) and i do notice that not every interface that is setup can be accessed through the GUI.
I have setup VLAN 1 on the WAN port (eth0) to connect to the edge router (because i need all 4 LAN ports) with IP 192.168.1.150 again. This i can´t access through the GUI. I have also setup a bridge for the wireless and VLAN 1 and this does provide access to the GUI.
Still not sure what i am doing wrong here but at least i now always have access on VLAN 10 (so far)
