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
