1st Option -
2 x EX820v in mesh
2nd Option -
UDM Pro with U6-LR access point (wired)
2 x unifi express using mesh mode.
Looking to maximise wifi speed as close to the 1gig as possible… or if anyone have any other suggestion to explore possibly.
I use a UDM Pro with U6-LR & U6-Lite and depending on location around the house only get around 350-400Mbps via WiFi
WiFi is all about location location location.
A bang average access point in a good location will out perform a top of the line access point in a poor location.
@Hopper is right that placement really matters. For best speed capability (on paper) with Ubiquiti you will want the U6 Enterprise APs which have WiFi 6E - of course your devices need to support it too.
It also has a 2.5gbps ethernet port so it can in theory support the full 2500/2500 Cityfibre package, although you’re unlikely to ever get that from a single client. If you are trying to get the best throughput then always pick an option where your APs are wired in (and avoid daisy chaining unless your APs have significantly faster ports than your internet connection).
I have now upgraded all my Unifi APs to the wi-fi 6 versions and currently have - in this purchase order - a U6 LR, U6 Pro and U6+. Certainly overkill for 2.4Ghz but to get a consistent 5Ghz signal in a house with internal brick walls, it seems better to saturate with multiple APs at a lower power, than less on a higher power. I have also been very wife-friendly with my positioning of these with 2 up in the loft resting on the ceiling boards, and one tucked away in the integrated garage.
They do take a fair bit of tinkering to get everything running well - power levels, positioning, frequencies to use etc. But, from the locations that I generally use in the house, I get around 600-650Mb down on wi-fi 6 supported devices which is probably not that far off from what’s realistically possible,
Depends on how much time, effort and headaches you want to deal with. I have found that it’s very easy to totally screw it all up by making one seemingly innocuous change with the Unifi stuff. Conversely, you should get much better performance when set up correctly and is a lot cheaper than Cisco or Ruckus kit.
One final note. Unifi have just announced their U7 Pro AP so that might well be worth looking in to for futureproofing.
