Fred99:
The wifi ability of the system seems to be great. The fact that there's no way to connect even the primary node to gigabit ethernet is a serious flaw I should have seen coming - so my stupid on that.
It actually solves about 50% of the issues I wanted to solve. Guest bedroom and garage now get good 100/100 wifi when it was near zero before, which is fine. The 50% it doesn't solve is that in my office (not where the router is) is stuck with kind of sucky wifi bandwidth, so I either fork out the $$$ I should have done for a better mesh system, or deal with spiders and unspeakable hazards, and run some cat 6 from the router position to the office.
So just to clarify (for my own understanding), you're not using wired backhaul between any nodes? Just the wireless backhaul?
