Hi all,

I'm currently running latest CM10.2.0, and when I connect to any WiFi network, the initial negotiation speed is very fast.
From the moment I push the WiFi button, to the moment the WiFi is "connected", the duration goes from 2s to 4-5s max.
This duration includes internal WiFI activation and DHCP lease negotiation.

With all KK based ROMs I've tested (CM11, Carbon, LS, etc ...), or with F4K kernel (KK or JB, I've tested JB version on CM10), I'm having terrible negatiation times, generally next to 30s, but sometimes as high as 60s.

Having to wait up to 60s before being able to perform a mail check or a calendar sync that takes only 3s is very annoying.

What can I do to obtain a descent activation speed with KK or F4K JB ?
Is there a build.prop tweak or an init.d script that can speed the thing up ?

Tks
