Hi there, I am seriously considering buying a 2nd router for myself mostly. I live with my family in a moderately big house (2900sq ft) and the router we have is already bad. It’s a actiontec MI424WR. It doesn’t even support 5ghz or 802.11ac. I used to have my PC a floor right above it and barely got 1mb/s. My ping would usually be 80s and often go to the 100s-500s. Sometimes I even got 2000. I had to move my pc even farther and often my phone will disconnect to WiFi bc the connection is so horrible. So I want to know one, how do you set up two routers on one network, and two, a good 2nd router under 50$. Thanks and have a good day.
