I own a business that has two main work computers, two phones using WiFi, and 5 wireless cameras. I struggle to get internet connection to the computers.
I have a TP Link Deco and a main router. There is no way to have an Ethernet cable to connect to either computer.
Internet constantly disconnects when I’m on the computer but I don’t ever have any issues on my phone. Our internet service provider says the only way they can guarantee high speed internet is through an Ethernet cable
Do your wireless camera need Internet access? If not you should move them to a separate network.
But I’ve worked with more devices in a single low end router setup. It might a problem with your computer.
