AX11000 Pro (Main) and AX82U (AiMesh Node)

[ItzJbenZ]

Just picked up the AX11000 PRO to pair with my original AX82U. Decided to go with this route instead of going with an Orbi, eero etc. I have it set up with wireless backhaul 5 GH-2. The only concern is the wifi speeds. When connected to the AX11000 PRO (Main), right next to it, I get about 800-900 mbps (located lower level split level house), when connected to the AX82u, (located main level) I get about 250-310 mbps, right next to it. Is this expected? I was thinking the speeds would be a lot higher. Is running a tri band with a dual band the issue? or some other additional configuration needed? ISP is 1GB Down - 40mbp Up

Note: When connected to the AX11000 PRO (Main), and right next to the AIMesh node, speeds are about 500 mbps..
