What is everyone's problem with mesh networking? My Google Wi-Fi 3 pack is literally the only thing that has worked stably and with the best speeds out of any other configuration I have tried. The issue is you will NOT get anywhere near gig speeds on wireless, not even close. I don't think there is any wireless solution that will get you close to that, and if there is then please let me know. Even the recommended higher end/more expensive mesh packages I've seen still say speeds up to 150mbps on the back of the boxes, so there was no point investing in those. I typically get ~130mbps in the majority of my home, which is still considerably less than the speed I pay for. That said, the signal is strong everywhere in the house, whereas I previously had a couple dead spots with other configurations. Unfortunately for me, Ethernet is not an option, so mesh was the only thing to work well, and it's frustration free. Google Wi-Fi mesh is the easiest wireless system to set up as well.
If I had a finished basement I would go back to having my router down there as well, simply because everything I use most would be down there and hard-wired for best speeds. Mesh routing would take care of any coverage in the remainder of the house. I've been using mesh for almost a year now and it's been a godsend. Zero issue's with any of the 14+ devices we've used on it, including 4K streaming.
