I have a Netgear Orbi mesh (1 base + 1 satellite) in my house. They're about 6 years old and don't support Wifi 6 (802.11ax?).
I've noticed that in my basement it works pretty well, but upstairs the effective data rate drops off VERY quickly when I move away from the router (satellite). I figure this is because of the large number of wifi routers in my neighbourhood competing for the same bandwidth.
Would upgrading to a Wifi 6-capable router help? Any other suggestions?
