This will give you a lan port
GL.iNet GL-MT300N-V2 (Mango) Wireless Mini Portable VPN Travel Router
the problem with that solution is, you have to manually switch between modes
I use my phone for this, works fine. Phone plus wap if you want an ethernet port?
yes certainly, if the phone does work like that i.e. it can use a WiFi connection for internet WHILST ALSO broadcasting an AP/working as a router for stuff to connect to, that might well work!
TBH I’d ditch the idea of using other wifi and just go with a dedicated mifi solution. I get 75gb of 4g for £15 per month
but actually yeah, coming round to this being the easiest solution 🤣 The only minor disadvantage is, won’t work in the rare situation where there IS a WiFi network, but no cell signal!
