Many users claimed to have had Wi-Fi connectivity issues when Screen goes off, with their Nexus 4 device running on Android Jelly Bean 4.2. Whenever phone is idle and display goes off after a 1 or 2 minutes, Wi-fi connection gets lost or stuck and receiving bytes stops.This problem has specifically appeared in Nexus 4 and Nexus 7 not the other models of Nexus Series including the  Galaxy Nexus, and an Atrix As users of this devices were totally snubbed to the WiFi connectivity issue.

Sometimes people aren’t sure if such a problem persist in their nexus  Device because one moment it seem to be working just fine but then it is present, So In order to make sure that you have this problem too and before applying the Fix, just ping your phone from another device that is also connected to the same network.

  •  Just Turn the screen on
  • ping the phone
  • you will get a response
  • Now Turn the screen off
  •  Try to ping the phone again  after waiting a couple of minutes
  • And this time you will get a timeout

BGNLEY @ XDA developers that is also the Source of this post, have come up with this fix, Just apply it and you will no longer have Wifi connectivity issue with you Nexus 4.

These all 3 files worked fine with my Nexus 4 using CWM 6.0.2.3. Make a CWM backup before Apply Fix. You can download and use anyof these. However the McastBcastFilter to 0 is recommended as it allows the phone to listen for multicast traffic while asleep.

File Type: zip n4-wifi-sleepfix-restore-original.zip – This restores the ini file to the original one from stock 4.2.1 JOP40D.
File Type: zip n4-wifi-sleepfix-mcast_and_bcast.zip -  This allows the phone to hear multicast and broadcast traffic during sleep.
File Type: zip n4-wifi-sleepfix-bcast_only.zip – This allows the phone to hear broadcast traffic during sleep, but not multicast.
