I have a question/problem, maybe some can help me.
I want to us my tp-link tl-wr810n-v2 with openwrt as accespoint for traveling and flashed openwrt 18.06.4.
I want to connect the device via lan and/or via wlan with local networks (in hotels, apartments and so on).
I connected to the tp-link via lan cable, logged in, set up wlan in ap-mode with static ip-adress and wlan.
If I than disconnect the lan cable and connect via wlan, i cannot access the LUCI-interface. But I have a internet connection if I connect the tp-link via lan cable to the local network.
I'd recommend that your uplink (i.e. the hotel/apartment/cafe wifi) is a WWAN (wireless WAN), not a wireless LAN. To do this, you should change your LAN IP/network to something that is uncommon and fairly unlikely to conflict (for example, maybe 10.24.134.0/24). Use TravelMate to manage your wireless uplink.
After a reset of the router, I installed travelmate. I set everything up, added a wlan, removed the ethernet cables and everything worked fine.
But after unplugging the router and plugging it in again, nothing worked. I could connect trough wlan, but there was no internet-connection and i could NOT access the luci web-interface to reconfig anything or check the problem.
