For 2 years now, I’ve been using an old Ruckus 63xx AP (standalone firmwire) to handle wifi since my airport extreme wasn’t strong enough when we moved. Covers all 3 floors, garage, and just reaches down to our water front (130’).
I have an archer C7 for my racing club, and it’s pretty powerful. I did a quick test a while ago in my house and it reached everywhere in our home. I should really test it again and see if it can reach our water as well.
I also have a buddy who put in a netgear orbi mesh system and loves it.
