I think it depends largely on age - “new builds” (1980s onwards) often have a brick partition wall down the middle and the rest plaster/wood stud. The last coup

I think it depends largely on age - “new builds” (1980s onwards) often have a brick partition wall down the middle and the rest plaster/wood stud. The last couple of houses (significantly older) I’ve lived in have been pretty much all brick walls. We’ve got 3 UniFi APs downstairs here, 2 up. There are still things on the periphery that only just cling on, and when you’ve got stuff like that it takes a lot of airtime.
