How To Fix Wi-Fi Problems on the iPhone 6/6 Plus

Greyed-out, slow or no Wi-Fi signal at all are among the top three biggest Wi-Fi headaches. Even though the iPhone 6 and iPhone 6 Plus came with iOS 8, Wi-Fi problems are still not completely avoidable. Before searching for solutions to Wi-Fi related problems, always update your device to the newest version of iOS. If that doesn’t work, then it is time to dig deeper.


1. Reset Network Settings


Settings > General > Reset > Reset Network Settings.


This is a solution suggested by Apple Service. Resetting your network settings including Bluetooth pairing records, Wi-Fi passwords, VPNs, and APN settings; which flushes cache and clears DHCP settings and other networking related information.


2. Disable Wifi Network Services


Settings > Privacy > Location Services > System Services.


This only relates to your location being used for network and not the Wi-Fi itself.


3. Switch DNS To Google


Often times, if your ISPs DNS servers are having problems, you can switch to Google DNS by going to Settings > Wi-Fi then tap the “i” icon next to your router, scroll down to DNS and tap the numbers, then enter “”. Restart your device and check if it works.


4. Change The Routers Broadcasting Band


Change the routers Wi-Fi broadcast from an N network to a G network, or from 2.4GHz to 5GHz – this depends on your individual router hardware.


5. Factory Reset


Settings > General > Reset > Erase all Content and Settings > Erase iPhone.


Last but not least, restore your iPhone and set it up as a new device.
