however when I run a speed test over wifi connection it’s usually in the 45mbps range. Will buying and using a 3rd party wireless router allow me to get the full speed or close to the full speed I’m paying for over Wi-Fi?
Wireless is half duplex, you are paying for 200 Mbps, the max you can get is 100 and then is an issue of the antena on your device, I get more on laptop, less on ipad and even less on iphone.
45-50MB is the max speed of a 2.4ghz channel, please make sure you’re on 5ghz
What is the modem/router model?
And what devices are you seeing the slow wifi speeds on? Your connecting to a 5GHz network correct? 45mbps sounds like 2.4GHz WiFi.
