What is the best Wifi Speed Booster App for a Samsung Galaxy S6 32GB?

[bryanw959]

I have Xfinity wifi, and a Netgear Nighthawk AC1900 R7000 router, and I bought my own modem- it's an Arris TG862G, and I bought a Netgear EX3700 AC750 WiFi Range Extender, to be able to get a WiFi signal in the detached garage. What's the best wifi speed booster app for me?

If your having wifi speed issues you need to look at your router configuration.
There isnt really any way to boost speed by using your phone.
Kinda of like those fake signal booster apps you see. Theres physical limitations to hardware and interference so having an app to boost signal isnt plausable.
Start with testing speeds directly from the router / modem. Then work your way out to different nodes on your network. You may see reduction in speed due to distance or your wifi range extender.
