Wow As of now this seems to have solved my problem. My Samsung tablet was defaulting to 2.4ghz and I was getting very slow speeds  and Samsung software does not allow me to choose 5ghz as default or preffered. Running this app seems to have forced my tablet onto the faster frequency  5ghz. Speeds are now 10x what I could achieve before on 2.4ghz.
