A good mesh system -- Google/Nest Wifi is one -- will do the trick. I have four of them for our house and it covers everything great, including the yard and driveway/garage (where I download most of my shit before leaving for the day)
There's a handful of mesh wifi systems and they're all pretty idiot proof from what I understand. I love the GOogle Wifi one because it's dead easy to set up, and it has an app that helps you find week points and position your access points in a way that covers more of your house. It also has great built in data tools, daily automatic speed tests that it saves for you, data use by device, total data use by month, etc. I'm sure the others are good too, but I'm happy with the Google Wifi one, and the 3 access point starter pacvk is a good place to start. I've pretty much never had to restart the wifi system, or at least, it's so rare that I forget when the last time I've had to do it.

Nice glad you got a good setup. One thing to remember is that 5Ghz band isn't always ideal. 5ghz is best for devices that are close to the access points, ideally without anything blocking them. 5ghz has trouble moving through multiple walls, fabric like curtains or mattresses/beds, shower curtains, etc. So while it can be really fast in the same room, just moving a couple rooms away can really kill performance. I had an issue with my old Pixel 3 phone where it *always* defaulted to 5Ghz in my bedroom but the access point was in the hall upstairs, and it made using xCloud/Xbox Streaming impossible in my bedroom, but if I walked .. like 15 steps to the hall, it'd be flawless. We have horsehair plaster w/ drywall *over* it in some rooms, old ass house, and so that basically makes like 2 walls the 5ghz band has to pass thru and it just totally fails. 2.4ghz would work fine but my pixel 3 refused to let me change bands, I don't have the problem anymroe.
