How do I get my full 75 mgbs download speed

Greggf1

My service doesn't seem to register higher than 20 mgbs.
I have a new wireless router from Verizon that they recommended I purchase at the cost of $100.
And still can't get the speed.
Things lag and video stutters and lags.

• make sure you are using WPA2 (new router should default to that)
• make sure your wireless device has wireless-n or wireless-ac, otherwise you are limited to about 20 Mbps at best
• If all your devices support wireless-n, consider setting router to wireless-n only (performance mode)
• consider change the channel to another value such as 1, 6, or 11. Most of your neighbors devices end up trying to use the same channel leaving no bandwidth for you to use.
• make sure you test near the router. Unfortunatly speed falls of as you move away or because of things in the way. If works well close, you need to consider moving router, or using multiple access points.
