I'm setting up OpenWrt for the first time and using a TP-Link Archer A7 for that.
What I'm trying to do with the Archer is to connect it wirelessly to another router which has internet to boost the wifi signal and create a wired connection in that spot. It should also have it's own IP-range to not really interfere with the downstairs wifi.
What I have done already is to connect to the downstairs wifi with one wireless interface in Mode: Client and set it to be on the network lan and wwan.
I've then created a new password protected wifi access point and also under the Network lan and wwan. Another thing that I've changed from the default setting was the router IP to 192.168.2.1.
But on both lan and wifi, I'm only able to connect to the OpenWrt admin page but not the internet.
I later found this in the documentation https://openwrt.org/docs/guide-user/network/wifi/connect_client_wifi but I think it could be slightly dated because the UI is a little bit different and changing the firewall settings like on the page didn't change anything.
Does anyone know how to connect these networks together?
