Hi, I have a 3 Storey house, my fibre modem is at the ground floor and my master room is at the 3rd floor (up the stairs twice). It's about 6m up and 9m diagonally to my room.

I'm using a Tenda Ac18 and it can reach my room at 2.4ghz about 2-3 bars but not very stable.

Any suggestion for a good range wifi router? I'm thinking of tenda Ac23 but maybe here got any better suggestion? Price preferable reasonable la about 200+ huhu
