iPhone 7 Plus Wi-Fi Issues

Below is a User Tip about Wi-Fi issues. Suggest starting from the top and working down. You have already tried some of these but perhaps the others may help. Try configuring the router settings as shown below.

1) Restart you device. If a normal restart does not help, hold down these buttons at the same time for at least ten seconds, until the Apple logo appears: a) the Sleep/Wake button and the Volume down button (iPhone 7 and iPhone 7 Plus) or b) the Sleep/Wake button and the Home button (all other models)

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.

I agree. I hope the DNS helps but the other steps are usually more effective and you have already tried them. FWIW, I had some issues with a particular brand of routers and ended up replacing the router which took care of my problems (the router company refunded my money). The new router has worked flawlessly with all my devices. I am not saying that that is your issue as it is impossible to tell from this end; just another possibility since your phone works well in other places.

I am having the same problem with my new iPhone 7Plus. My 6 NEVER had an issue, but this one is absolutely relentless in losing connection even with my router in the very next room! I have followed all the steps recommended by Apple, but nothing has worked. I'd like to avoid going back to the store, but if I have to - I certainly will rather than continue to deal with this. Not to mention, all the time I'm unable to connect to my home Wi-Fi, Apple is forcing me to use my data. Not good.

Number 3 worked, got my phone back on wifi.

Thanks

Glad to hear... 🙂
