I have an Archer C3200 router. I believe it is around 4-5 years old. Not sure. We have a two story home with a bonus room above the garage. The router is in the bonus room. We chose this location so we had a stronger signal upstairs. Locating router on first floor did provide a decent signal to each end of the house (bonus to bedrooms on opposite side of second floor). We have around 17 devices connected to the WiFi. Most TVs do not stream without interuption. We cannot connect our printer to the network reliabilly. Total sq ft is 2200. Do you recommend an upgrade? If so, which model? Do you prefer mesh routers over single point?
