Wifi Diabled after upgrading the I9082 to 4.4.4(Rooted) topic

Guys,

Need your help in fixing my problem.

I have rooted in to my Samsung Galaxy Grand I9082 and upgraded the device to 4.4.4 using the file(CosmicCM-4.4.4-5.4.stable-20140911-034838-k2wl-i9082.zip) and now WiFi is not getting activated at all. Can someone shed some light on this to fix the issue.

Thanks in advance,
Siya
