WI-FI ROUTERS and Modems. BEST!! brand and why.

I'm a big fan of the Linksys Velop. 

I have the 3 unit setup and have one unit installed on each floor of my home. Each unit has two ethernet ports on them and I'm using one of those to handle the backhaul channel through ethernet.  I can regularly get 600 Mbps+ speed internally between devices throughout the home.  I have a 900 Mbps connection into the home and actual throughput (via Speedtest site/app) to my laptop and iphoneX via the wireless 802.11ac band is around 480Mbps with 32 devices connected.

Netgear Triband 4000 to NAIM Atom 
tidal and full size NAS files work great with fantastic Sonics 
eventually will run a wire of if installer is skilled fiber
router has required an almost daily reboot if I leave Radio streaming 24/7
.... could be a NAIM issue, not sure

Manged Networks for a large Software Company for years. I use to use Netgear and Cisco/linksys for years but over time they have become buggy. disconnects for no reasons slow downs etc. I switched to Ubiquiti a few years ago and have had zero problems, but in all honesty I have a TP-Link wifi setup for guest access and it work more reliably than anything I have had, and it's been rurning for over 10 years. 

With that said, all my audio gear runs on a wired network and the only thing on wifi are phone, tablets.For wired I have Netgear all around.

YMMV

ORBI and Fiber. Simple and fast. 

Happy with Orbi here.
Plan to add another satellite and then run Ethernet directly from the satellite to another Roon endpoint for my outdoor system.
