I just replaced two wifi access points which were using two old AC-1800 routers by a single Asus RT-AX86U Pro, bought on a clearance sale. Placed in the middle of the house, it is better in every way, using a single 5Ghz radio. Stability, speed. And better security with WPA3. The stock Asus firmware surprisingly has quite convenient cool features. Multiple guest networks, Wireguard VPN client.
In short I am very happy since 3 weeks since the switch from Wifi 5 to 6. Now I read Wifi 7 is better!?!? Checking the price, a full featured Wifi 7 Asus router is at least double the sale price of the RT-AX86U Pro. I am going to pass as I have no need of increase speed.
