I am looking to improve the Google Fiber mesh network that I have setup in my house and was wondering if anyone had any advice on this. I've done some research and the two main solutions I've found are 1) connect all mesh extenders via wired connections (not feasible for me) and 2) upgrade the hardware, since Google's hardware isn't the greatest.

I'm unsure which hardware would be best for replacing Google's router and extenders. Would anyone have suggestions for new hardware?
