I did in my house which was built in the 1950s or 60s and it works. With that said, it was only ok and I wouldn’t use this for anything but internet access and some light streaming. This was 10 years ago so it is possible they have gotten better. I have since moved to mesh wifi and it literally solved every issue I had and the whole house has incredible wifi no matter where you are. Plus I use the AP’s to plug in my more dedicated stuff since it’s faster than wifi to use the backhaul the APs use to communicate with. I do wish I could afford to redo my house and put in ethernet wiring everywhere and have a dedicated switch for everything.
From my understanding, if the original country they originate from does not take them, they can end up in another country that the US has made deals with. That will take time to negotiate, and during this time, they will sit in camps…
