How to Fix Android Jelly Bean WiFi Issues

If you have installed the latest version of the Android, Jelly Bean, you must be busy in exploring its features. 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. Apparently the issue has affected all the users who just installed Jelly Bean on their devices. 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.

I. Before You Begin:

1. You must have rooted your device before doing this procedure. Please head to our Android How Tos section to find out the rooting procedure for your device.

2. You must have ClockworkMod Recovery installed on your device. You can browser our ClockworkMod Recovery archive to find the installation procedure for your device.

3. You must be running on the Android Jelly Bean.

4. The following procedure works on Verizon Devices only.

II. Downloading Required Files:

1. Download the Fix File from here. (First link in that post)

III. Fixing Android Jelly Bean WiFi Issues:

1. Place the downloaded Fix File on the Desktop of your PC.

2. Connect your device to your PC using the USB cable.

3. Copy the Fix File to your device’s SD card Root folder. Make sure you are not putting the file in any deep folder.

4. Disconnect your device from the PC after the file is successfully copied.

5. Reboot your device into the ClockworkMod Recovery. The key combination to get into the recovery mode varies by the device you have, see the ClockworkMod procedure for your device to know it.

6. Once you are in the ClockworkMod Recovery, select install zip from sdcard and then choose zip from sdcard.

7. Navigate to the Fix File you copied to your phone in the step-3 and select it for flashing using the Power key.

8. Choose Yes on the next screen that prompts you for the flashing. The flashing will then begin.

9. Once the flashing is finished, choose reboot system now from the recovery menu.

Your device will reboot and when it starts up, you will see that the WiFi is working fine now, problem’s solved.

    As said in the “official thread over at XDA”, this fix is ONLY for VERIZON Galaxy Nexus running JellyBean custom rom (since jelly bean is not released yet for the verizon galaxy nexus)

    The GSM Galaxy nexus does not need this fix.

    • Mahesh Makvana

      Any user experiencing the problem can use this procedure to fix it.

      • Mauro Bifulco

        So can i do that ? i have the same problem

      • Mauro Bifulco

        So can i do that ?

        • Mahesh Makvana

          Yes, you can do it.

        • Mauro,

          Do NOT use this on your GSM device. This fix is for Verizon devices only, Mahesh will be updating the procedure accordingly. Truthfully though, your GSM device shouldn’t be having WiFi issues. If it is, I’d suggest trying a different custom ROM.

          Hello Mauro,

          After doing a thorough research, I found that the fix does not work on the GSM devices. It works on Verizon devices only and is recommended to apply on the same.

          I apologize for the little mistake I did.

          Thank you !

        From the OP on XDA to a GSM user:

        “This is the Verizon CDMA forum. You don’t need a ‘fix’ because the jelly bean developer preview is for gsm devices (CDMA devices do need it). You should restore your stock rom files to fix your problems.”

        the fix is for cdma devices, it break things in gsm devices!

        • Thanks for reporting this, I’ll have Mahesh fix the procedure so it says only for Verizon users. Sorry for the confusion.

  • Mauro Bifulco

    Does it work with gsm-yakju devices? Guide says it’s only for verizon versions. Sorry for my english , i don’t speak the language

    • Mahesh Makvana

      If you’re experiencing difficulties with your WiFi, you can try this fix.

    • Mahesh Makvana

      The procedure is intended to be used on Verizon devices only. We don’t recommend you to try it on your normal Nexus Prime.

      Thanks Hamza!
