Lath and plaster walls have a distressing tendency to be lined with chicken wire mesh which really damages your chances of any radio signal getting through.

Pictures for anyone wondering what it looks like:

Wired wifi mesh or Ethernet all over would be my prescription. You basically have Faraday cages in every room right now!

I’ve strung CAT 6e from one end of the house to the other to link 2 of them. The 3rd’s in a place not amenable to cabling without way more effort than I’m up for, but it’s close enough to one of them that they mesh alright.

Ethernet/fiber is far better in that scenario. You may even have better luck using existing coax and moca adapters than wifi in those scenarios.
