I have a GL-AR750s / Slate with the latest V3.100 firmware, and am running into the following issue:
When connecting to a guest network with a 192.168.x.x address I never am able to successfully route traffic over the Wireguard (in client mode). I would like to note that my Wireguard network is 192.168.20.x/24 and the hotspot’s network does not interfere (e.g. 192.168.6.x/24). I have a similar Wireguard configuration on my phone, iPad & Mac laptop, and do not run into the same issue.
