Some of the users who have installed Jelly Bean on their devices say that the WiFi performance has become quite weaker than what it was in their previous ROM.

To fix the issue, an XDA developer has come up with a file that you can flash on your phone to get rid of the WiFi issues. Following is the complete guide on how you can fix this issue.
