RE650 Range Extender very slow

I cannot achieve anything like the potential speeds of my home network using the RE650 (in extender mode).
My home wifi runs at 100MBPS consistently as per speed test result below:
If I plug in the RE650 in the dining room, maybe 10-15m away from the main wifi router, my Android phone shows the same speed is possible, 100 MBPS. But if I plug in the RE650 in that location, the attainable speed on the main wifi network suddenly drops to 36MBPS - I can only assume channel interference:
Then if I connect via the RE650 itself, the speed drops to around 9MBPS, which is obviously pathetic when it's telling me I have a strong signal and can be further away from the main router:
I don't know how to find out the hardware or firmware versions of this unit although I expect that could be relevant. I have the TP-Link Tether app but can't see any way to get to that information. Is there a standard admin IP address for the RE650 with more details available? I tried 192.168.0.254 while connected via wifi on my Android phone but it gave a 404 error.
Why would it be so slow? The best it has achieved is 35MBPS when mounted outside the back of the house, about the same physical distance from the main router as in this test. It should do much better. What should I try?
EDIT: Even more strange, the 5GHz range extender wifi is super fast, almost 100MBPS, even when the 2GHz network is 9-10 MPBS in the same location. There are no other 2GHz signals in the house that I know of.
