Hello, I provide network services to small businesses in Argentina. I install a wired network with a mikrotik router and place TP LINK TL-WR841HP routers in access point mode in places where WiFi is needed. But when I put more than 1 TP-Link router the problems start: The network becomes very slow, both for clients who access via WiFi, and for those who access by cable. If I disconnect the TP-Link routers everything goes back to normal for a while, but if I connect them the problems start again. For example, when I ping it shows me times of 50m when the normal is <1m. This has happened to me with several clients and I have had to disconnect the TP-Link access points. Could it be that I am doing something wrong?
