I'm also looking for ways to maximize the connection from my RT-AX86U. I was thinking of upgrading from my current 750Mbps to 1.5Gbps but, as far as I understand it, the one active port from my fibre ONT only supports gigabit ethernet, so even if I install a multigig switch and run it to the 2.5Gbps port or play around with some sort of link aggregation, I won't get more than 1Gpbs to one device from the router. If I want more, I think I have to play around with a switch or router that supports a direct connecting to the fibre's SFP module.
I'm pretty to new to this so I only marginally understand it all. So, I guess my question is, does the new Telus Wi-Fi hub enable any of this to happen easier?
