Slow and inconsistent wifi on KitKat topic

Hi all

So I have the the Poland official kitkat rom

Not sure though the problem started from then

Anyways the thing is the connection speed I have at the house is 8mb/s

And from all the devices I get a straight and consistent 7mb/s
Ex ipod pc galaxy s2/s3

Except for my note 3, it hardly gets to 3mb/s

(Using speedtest app)


And always goes like 0.5mb/s to 1 and changes unstable

Searched alot and tried everything but none got me to a solution
Ex in advanced settings in wifi removing the tick
Removing the powersaving wifi in the service code


Looking for further help

Thank You
