cw1200_wlan, Wi-Fi consuma eccessivamente

[Pulse]

Ciao a tutti! Ho un problema: ultimamente, qualsiasi rom io abbia, BetterBatteryStats mi rileva un wakelock WiFi-correlato ("cw1200_wlan"), che mi consuma eccessivamente batteria anche se apparentemente non scambia dati.

Spoiler:

Allego anche il mio build.prop, se può c'entrare qualcosa..

CREDO di aver risolto.
Ho modificato la voce "net.tcp.buffersize.wifi=4096,87380,256960,4096,16 384,256960" in

net.tcp.buffersize.wifi=524288,1048576,2097152,262144,524288,1048576

.

Niente, riapro il tema della richiesta in quanto questa soluzione ha funzionato solo per poco tempo. Qualcuno ha qualche idea o lo stesso problema?
