Walls are very thick 0.5 - 1m, I dont think ill be able to run a cable due to the layout of the property hence looking at wireless options. I'll do some more digging but suspect the udm + wireless meshed ap will be my only option. I'll do some reading on which ones will give me what I needHow thick are the walls? If it’s genuinely only temporary them I’d buy a 50m flat Ethernet cable and run it outside, passing it under the window openings. Cheaper and much more effective.
