iPhone 6s on iOS 11 unable to join wifi network

I updated my iPhone 6s to iOS 11 and I can no longer join my WiFi network. I know the password is correct and my modem/router are working properly as I am able to connect on my work iPhone without problem. Same with a few friends I had over.

What I’ve tried:

- soft reset

- forget network and rejoin

- reset network settings

- disabled WiFi networking services

- toggled WiFi assist

- setting custom DNS

I would like to avoid a hard reset and restoring form a backup at any cost as I’ve run into a ton of issues with doing so in the past resulting in losing everything. Any other troubleshooting ideas?

Fixed by simply renaming WIFI network name (Or SSID Name). I tried all of these below. None of these worked for me. Renaming forced other devices to reconnect, but I had no problem reconnecting other devices with new network name as I had only 6 to 8 devices.

My Phone: iPhone 6, iOS 11.2.6

1) Force Restart

2) Wifi Channel change

3) WMM disable

4) Router restart with router being off for 2 mins. Nope.. it didn't work. Tried unplugging power card for both modem and router. That also didn't work.

5) Static IP for my iphone

6) Disabled Wi-Fi Networking

7) Reset Network Settings

8) Forget this Network

9) Removed Share My location devices except current one.

8) Disabled WiFi assist

9) Disabled WPS

10) Enabled IPv6 in Netgear Router

11) Even moved away 5 miles just to make sure different Network gets picked up from LTE and hoped that would flush some WiFi network cache along with LTE cache if any. Realized I didn't have to do this stupid thing of moving away from home as they are not at all related. But, you never know stupid things work some times. 😁

12) Disabled WiFi and Enabled WiFi multiple times.

13) Tried Airplane mode and disabled Airplane mode

14) Tried personal hotspot on another phone to connect from problem phone and see if that would flush cache.. Nope that didn't work either

15) Finally the only thing that worked for me was RENAME THE WiFi Network Name for both 2.4GHZ and 5GHZ.

Hi. I’ve been having problems and the only way I got it to connect to WiFi was to add my FaceTime to my Apple ID. So turn it on. Then when it asks you to connect to WiFi. It asks for your Apple ID and then it says connect to WiFi. Luckily I did and my phone actually excepted my WiFi password which was saying incorrect password before.

It still says not connected when handset is first opened. But stays connected. but this is the new iOS problems for certain handset, my iPad has no problems. Worth a try.

Hi recently after updating to iOS 11.0.2 on my iPhone 6s and iPad mini 4, it gives me error message WiFi password is incorrect but WiFi password is correct I could connect with the same password via my laptop and android phones, it's a clear bug in iOS, after 10-20 tries it somehow connected..

I receive an “Unable to join network” error message. I haven’t tried to access another network yet but plan to do so when I get to work today.

I have this problem. Worked for few days then from last night it will not connect on my 5s. iPad is connecting fine I also done all above and keeps saying wrong password even though correct. I’ve also tried manually adding my router details etc and still won connect. iPad is fine. Must be iOS problem on smaller devices like 5s upwards.

No problems with iPad. But relie on my phone for Wi-Fi, so not handset but iOS problem.

Already done all this before coming on here. I’ve resetted everything on network and router. iPhone will NOT connect. But iPad no problems. It’s obviously the update. But nothing new for Apple! Not only me having the same problems with handsets higher than 5s.

I'm trying everything I can to avoid a hard reset. The last time I did a hard reset of my entire phone I lost everything and couldn't restore from a backup. I am willing to wait for another update to see if that fixes it before resorting to a full phone hard reset. I have tried a network reset though.

Wow. Interesting to know. This is the first time I am hearing of a user losing their data from a hard reset. I guess I will be cautious giving out this method unless deemed necessary. Thank you for this information. However, the new update should be available for your device. Please let me know if it fixes the problem.

I updated iOS 11 and then to iOS 11.0.2 few days back on my iPhone 6s, since then my iPhone has stopped connecting to WiFi. The options getting displayed are that either the password is incorrect or unable to connect to WiFi. I am also unable to connect to hotspot created on an android phone though on an iPhone I am able to connect via an hotspot. Further, I have an iPad and another iPhone 6 which is getting connected to the same WiFi or any other WiFi wherever I am trying to connect them. I have tried the following steps independent of each other to solve the problem-

1. Resetting and erasing the network settings.

2. Resetting the iPhone to factory settings.

3. Disabling WiFi on location settings.

4. Resetting the router.

5. Removing the password on my router and then trying to connect.

None of the above steps have solved the problem. The only time my iPhone gets connected to WiFi is at the airport where I don’t have to input a password to access the router but put in an access code in a webpage provided.

I have had this problem as well. I did a hard reset - no luck, also sent it back to 10.3.3 where it use to work fine and that did not help either. Took it to the Apple Store - diagnostics checked fine and was told the next update would fix it. That was 11.1 - no luck - same with 11.1.2 - getting frustrated! Anyone have any ideas? Also - my Bluetooth is also messed up since updating to 11. BTW iPhone 6S

I’m having the same problem with my iPhone 7. I’m currently abroad and when I try to connect to a wifi it says unable to connect. Even when it’s a free wifi. I can connect to wifi with my iPad. However, when I try to connect my iPad to my iPhone to use cellular data it will not connect to my iPhone. I was going to do a software update but the funny thing about that is that you need wifi to do that. Catch 22. So ****** right now.

I have the same issue with my iPhone 6 upgraded to iOS 11.2.1. Other members of my family can connect with the same password.

I have tried resetting network settings. Didn’t work.

It is really frustrating! Need a quick solution.

I have the same issue on my iPhone 6. Since I am traveling I just got a message I am now facing 400 Eur additional roaming charges. Thank you Apple. I tried all suggested fixes and nothing works. At the Apple store they said they didn’t see a problem. Not good and very disappointing. I guess this is how they get people to upgrade device
