[ale] [Semi-OT] Second WiFi in the house?

[Leam Hall]

Is there anything particular to look for a second wi-fi in the house.
Our phones are old, and our current wi-fi switch is old, so we keep
getting dropped and then using all our limited data. My thinking is to
get a second wifi and run a wire to the living room, which should give
us coverage. It theory it should be easy, but I don't know what I
don't know these days.
