I current have 1 gig cable service. Using Google wifi. I have the main router plus 4 access points.

Testing speeds at the router itself, I get about 850mbps. No device on wifi gets more than about 150mbps - even with most devices powered off. I've been very unimpressed with their mesh system. Nodes drop offline, and speed is horrible on other rooms - usually 25-50mbps. Maybe I just got a bad system, but my regular old non-mesh router is faster - coverage just isn't sufficient.

I'm changing providers and going to a 2gig service. I know I won't see 2 gigs on my wifi devices. I don't have unrealistic expectations. This 2gig service is cheaper than I'm paying for the 1gig service with my current provider.

Can someone recommend one of the best mesh systems?

Home is 4500sq ft. Upstairs and down. 4 bedrooms, 2 living rooms. 4 phones, 4 TV's, three gaming consoles, 2 laptops on wifi at any given time, plus another handful of smart home devices. Things like TVs and gaming consoles are going to have older network adapters that will limit their speeds. I get it.

I do not have any cable ran to any of the rooms, but I would consider running some if it made a big difference. I would prefer not to.

I don't need VPN or any sort of antivirus. I just need to be able to open some ports, etc. Parental controls would be a bonus, but not necessary.

Budget? Would prefer to stay under $500 for a 2-node system. Would add more nodes at a later time if necessary.
