Q: wifi 9.3.5

After updating my iPhone 6 to 9.3.5, my phone lost the ability to connect to my home wifi unless I am within 5 feet of my modem. The signal weakens then cuts our within 15 feet (I live in a 5,000 sq ft house that has wifi for all the other devices AND my iPhone before this update... iTouch no longer works and my bluetooth speaker has to be within a few feet of my phone as well. I have contacted Apple support. We backed up and restored my phone, reset network setting, rebooted at least a dozen times, and Apply checked my phone remotely for hardware issues. The Apple support person stated she has received MANY calls about this issue. Is there any way to go backwards and take this ios update off of my phone?!?!?! When will these issues be fixed? I have already reached 90% of my data halfway through the month because my wifi does not work within 5 ft of my router at home.

iPhone 6, iOS 9.3.5

    There is no way to go backwards and regardless of what you were told I have seen no unusual traffic here on the issue. I suspect you got a corrupted upgrade and Step 8 may resolve. Nonetheless I would start with the easy ones first. Don't hold your breath about a "fix" as it is likely not coming. I cannot tell you how many posts I see blaming a "bug" for an issue when in reality the issue is with the device or the system install.


    Suggest starting from the top and working down.

     

    1) Restart you device. If a normal restart does not help try holding down the Home and Sleep buttons at the same time for about 15 seconds until the Apple logo appears.

    2) Reset Network Settings:  Settings > General > Reset > Reset Network Settings. Rejoin the Network again.

    3) Reboot Router/Modem:  Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website for a newer FW). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band). Channels 1, 6 or 11 are recommended for the 2.4 band.

    4) Change to Google's DNS:  Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4

    5) Disable device prioritization on the router if this feature is available. Also disable any VPN apps and test Wi-Fi again.

    6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).

    7) Try device at another Network, i.e., neighbors’, public coffee house, etc.

    8) Backup and Restore the Device using iTunes. Try restoring as New first and testing it. If ok try restoring the backup (the backup could be corrupted).

    9) Go to an Apple store for hardware evaluation. The Wi-Fi chip or the antenna could be defective.
