Many
iPhone 6s and 7 plus, even iPhone 8 users are facing issue to join WIFI network
after upgrading to iOS 11. User is not able to join wireless network as able to
do with iOS 10 on same network. While trying to connect to network iPhone user receives
a pop up “Unable to join network”. The
issue is also reported on iPad devices. iPhone “Unable to join network” error is
mainly reported for wireless network over Routers only.
Most of
the apps work with Wi-Fi and it will make them useless if iPhone is not joining
to WIFI networks.
How to fix iPhone “Unable to join network” issue.
Fix 1: Change Router settings
The
error message “unable to join network” seems to occur with specific Wireless Network
routers, So if your router support dual band routing try to test connection
with other network.
Change
the router settings eg to choose channel “6” instead of “Auto” or e B+G instead
of B+G+N. (depending upon router model)
Also change the security to WPA2 from WPA. This should fix iPhone not
able to join the wireless network issue.
Fix 2: Restart
Router and Restart iPhone or iPad
Restart
Router: just power off your router and power on it again. And once done Restart
iPhone, now try again to connect to WiFi.
Fix 3: Reset Network
Settings.
Reset
Network Settings: Settings > General > Reset > Reset Network Settings.
It’ll require you to put your password. And this operation will disconnect all
Wi-Fi networks and erase passwords you’ve entered. Now set up again to connect
to Wireless network.
Fix 4: Upgrade to
latest iOS
WIFI issues and similar network issues can be
fixed by Apple in upcoming fix. Latest iOS 11.2 seems to fix many iOS network issue
but also reported with WIFI dropping issue. Hopefully Apple will come up with permanent
fix for these issues
