Yet, I run just one of the Hub 4 1Gb ethernet ports through a GT-AX11000, but still only max at 948Mb. I guess the difference is due to overheads / built-in latency?

I know it seems picky, but it's nice to have explanations.

If you are in modem mode, then the one port feeding the AX1100 is constrained to 1 Gig.

If you are in router mode, then two LAN ports can each download to a maximum of 1 Gig. So, if you have, say, two PC connected to the Hub 4, each downloading at 550 Meg, then the speed through the Hub 4 coax (the WAN port) will be > 1 Gbps.

If you are in router mode and the AX1100 is connected to one of the Hub 4's LAN ports, it is still constrained to 1 Gig.
