TUF-AX4200 have speed of 3603Mbps on 5Ghz band, so half of that would be 1800Mbps, even faster than XT8 node which is 1200Mbps. So, theoretically can support Unifi 1Gbps plan with this setup.
Correct me if I'm wrong.
Wrong
First you need to factor in a 50% discount due to retransmission consuming the airtime.
Then, factor in around 60% singal reduction after 2 walls and another 40% capacity lost due to overhead.
3603*0.5*0.4*0.6 = 432Mbps, this will be the realistic maximum speed you can get when connected to TUF-AX4200 on wireless backhaul to ZenWiFi XT8.
Even you add another XT8, the theoretical maximum speed on wireless mesh node is around 700-800Mbps
If you want Gig speed on mesh node, only the XT12 can do it reliably.
