Hi

I have a house - 2 floors 200m2. I have ethernet cables in 4 rooms. I want to buy archer ax50, place it in the center location of the house on ground floor (near fiber modem) and connect router via ethernet with 3 re505 in onemesh mode on 1st and 2nd floor. Will the onemesh works via ethernet? Is it make sense or should I think about deco mesh system?

And are Ax50 and RE505 good choices? Connection is stable? Roaming is ok? Because I read different opinions and I'm little confused.
