A:AnswerHi! Yes, the RE505X supports 100 - 240V, 50/60Hz. You may need to use a plug/socket adapter to fit the outlet of your region, since the RE505X sold here utilizes a US-style plug.
A:AnswerIf you have a compatible router it doesn't matter who your service provider is. I have Spectrum and the Archer AX 11000 router with this in my living room and it works great.
A:AnswerI tried paring it with my eero Pro 7 and it is NOT compatible with that router. I used all three methods in TP-Link videos and their "Tether" app just suggested I go to a weblink that turned out to be a hacker site that my firewall shut down. I suppose that it is possible that this may work with an older router system like the "two cans and a string" version or something.
