iPhone 6s on iOS 11 unable to join wifi network

Looks like its happening on certain N Type routers. Here's what i did, i changed my router setting to use B+G instead of B+G+N, and that fixed the problem.

I tried different Wifi networks and those networks are not in my control and its the same problem across.

None of suggestion/tricks/hacks are working for me and it seems to be a hardware issue and apple team *****.

I'm also have 6s and m having same problem

I anywhere do not have access to the router and it's so frustrating.I am using my data plan these days.😟We should raise a support case and sue apple for this issue.

I had this issue until I figured out this solution. I changed the router settings to choose channel “6” instead of “Auto.” I also changed the security to WPA2 from WPA.

Me too

I dont know what’s happened

From now i cant use my wifi

This did not work, still having issues connecting. Waiting on a patch to fix this.

This worked for me!

So frustrated! What do you do? 😡

My iPhone 6s as well no more able to join WiFi. Few days ago I followed instructions on screen it’s work just that day now again doesn’t work try that fellaas
