Smile [Q] Wifi problem with Touchwiz

Hi,
I've meaning to ask this a while ago but never had a chance to. I also tried looking for threads related to wifi problem with the note 3, but they all dont seem to be the same problem as the one i'm having.

Whenever I use touchwiz roms: Darthvader, Jedi, Hyperdrive. My wifi connects but would stop working after a while of not using my phone. The wifi icon says it's connected but nothing would load, I always have to turn wifi off and on to fix this problem, then when phone idle for a while then the problem would come back.

However when I use AOSP roms, the wifi is working great. Always connected like it should be. Anyone else have this problem? Is there any fix that I haven't heard?

P.S Sorry if what I said is confusing, English isn't my first language.
