Sounds like a configuration the router previously had was set to work better with gaming maybe? (maybe like some sort of QOS or something, or even dns settings , really it can be anything config wise) If it was working fine til you reverted back to default settings then that is your problem. Cabling wouldn't stop working and cause this to happen at the same time you reverted IMO. I personally would check the routers config and go from there!

Is there a limit to the amount of cameras that can be used? Wanting to do this with roughly 10 raspberry pi zero w /cameras and one raspberry pi 4 as the hub (mainly to live view all of them and motion alerts) then also a standalone PC as well acting as another hub mainly for storage and cloud services.

If you feel as if you can trust it then go for it! let us know how it performs if you do I'm interested. But @Razor Blade makes a good point depending on your network use there is many different setups and solutions you could do! Is running a 30-50FT cable not possible and just hard wire directly in?

This should work as long as you disable wireless and DHCP on the wrt router. Google wifi HAS to handle giving out the address and other things like wireless for the mesh part to work. the main google wifi router should be in NAT mode and everything else will need to be in bridge mode on the network. If the wrt router is handing IP out or giving of wireless you will experience double-nat, speed issues, inconsistent connectivity and so on it just won't be good.

In MOST cases if you add a firewall or VPN into google wifi you lose mesh and other main functionalities.

The one I linked will work for a fact and I trust them as a company! Them, Netgear, Asus, Ubiquiti etc... well-known companies will be the best bet! @Siddhant Mishra

In theory, it seems as if it should work!

As @Razor Blade said check your manual for the repeater if it supports that setup then yes!!

WAN- wide area network this is for if you ran a cable from like your main router, modem etc... to the wan port thus giving the device the ability to give other devices a network connection through the LAN ports. LAN-Local area network is for if you like what you wanna do in your other post, run the cable from the repeater to the device (computer, Xbox, PlayStation, tv etc..) giving thus devive a wired connection, it is for your local devices. Any more questions let me know! Thanks,

Using a wire is always better, but since you will be wiring into a wireless repeater it won't be true "full duplex" but better than "half duplex" from wireless. Ethernet is better whenever possible!!?

Cabling is one of those things that just take practice. I've done many cables myself and still struggle sometimes.

I currently use google wifi, for a somewhat mesh-based system it is not bad. It is not a true mesh system though. You don't have much control when it comes to settings it is very straightforward, simple and easy so if you are looking for that its worth it. IF you want a lot of settings and customizability i would look for something else. Other than that the speeds and everything are fine. I do have mine all hardwired back to a gigabit switch so that's some you can also do if possible for best experience!
