[Q] Xperia L Overclock Kernel topic

I really wana know if is there kernel, that will give you JUST OVERCLOCKING FEATURE to 1,5ghz.

Not looking for kernels in Xperia L section those always mess up my WIFI

heres example what i mean
1) no WIfi - cant turn on
2 Wifi Disconnecting - I'm on wifi and all the sudden it dc me
3)It just takes too long to find the Wifi i want to join
4) Not SHOWING WIFIs- it doesnt shows the wifis it showed before
5)Wifi is okay but the signal is lower for some reason so again DC

Tried everything,but after all one of these 5 things will apear.

So if you could help me find some kernel, that only gives me OC freatures go ahead and post it here THX.
