We currently use a WiFi 4, 1x1 router attached to our modem router with gigabit fiber connection to internet. WiFi suits our needs. Streaming, video calling, updates. Very rarely at the same time.
Laptop consistently reports MCS index 6 or 7 with corresponding TX rate. 6 right now with four clients. For some reason internet speed test, I assume not limited by the service, is always below 30.
Given our modest needs, there will any benefit in upgrading beyond AR300M? I would expect to connect at about 150 TX rate. And anyway speed of obtaining something from the internet is already way below even the current rate. Am I wong?
