Same problem with a 5 SE, no solutions to be found anywhere, I have traveled extensively through cyberspace looking for some kind of answer, but so far have found nothing. If anyone who does have an idea reads this could you please post the idea here, I'm prepared to try pretty much anything at the moment, including throwing my iPhone off the balcony in frustration... I'm really sick of spending my precious free time trying to sort out bullsh*t with expensive hardware. This phone has been a big waste of time & money. Thanks Apple.

iOS 9 brings its own share of inherent bugs and post-update issues such as persistent Wi-Fi connectivity problems like any other major iOS update. Some of the recently reported issues include inability to connect to a Wi-Fi network, unexpected error messages with incorrect password entries, intermittent connection issues and/or extremely slow connection speeds.

Check out a few simple tips and tricks (below) to fix the Wi-Fi connectivity problems on your device running iOS 9:

Reset network settings

Several connectivity problems can easily be resolved by simply resetting the network settings, which will clear the memory caches and DHCP settings to get the default or factory recommended settings. Here is how to reset network settings: Open Settings app > go to Settings > General > Reset and tap on Reset Network Settings.

Force Restart

Force restarting your iOS device is the preliminary step that you should try before anything else. Press and hold Sleep/Wake and Home buttons simultaneously for at least ten seconds and then release them once the screen shows the Apple logo, following the reboot.

Disable Wi-Fi networking services

Several users have reportedly resolved Wi-Fi connectivity issues by simply disabling Wi-Fi networking services. Here is what you should do: Go to Settings > Privacy > Location Services > System Services and disable Wi-Fi networking services from there. Note: This will only disable location services for Wi-Fi networking, but it will not affect Wi-Fi functionality entirely.

Forget Wi-Fi network to fix password incorrect prompt

Those who are unable to connect to any Wi-Fi network due to unexpected errors with password prompts (despite entering the right password), can try forgetting the Wi-Fi network and then attempt rejoining the network.

To accomplish this, go to Settings > Wi-Fi and then select your Wi-Fi network from the list by tapping on it. Then tap on Forget This Network option. A pop-up message will appear on screen asking your confirmation to forget the chosen Wi-Fi network. Just tap on Forget option to forget the network.

Now try rejoining the Wi-Fi network by going to Settings > Wi-Fi and then selecting the same network again. Enter the password when prompted and you are all set.

Set Custom DNS

Sometimes the network connectivity problems could be triggered by problematic DNS servers from your ISPs. In such cases, you could switch to Google DNS or OpenDNS to resolve the problem:

Open Settings app on your device, and tap on the Wi-Fi menu.

Locate your Wi-Fi connection from the list of available networks, and tap on i button on the right.

Scroll down to locate the DNS section, and tap on the numbers to the right.

Enter the new DNS server address using the virtual keyboard that appears on the screen. Tap on Wi-Fi to go back to main screen, once you are done.

Google DNS: To use Google's DNS for improved speed, performance and security, use any of the following addresses in the DNS field:

8.8.8.8

8.8.4.4

OpenDNS: You can enter either of these addresses to use OpenDNS, which is known to offer better speed, reliability and security:

208.67.222.222

208.67.222.220

Restore and setup as new iPhone/iPad

If none of the above steps fail to resolve the Wi-Fi connectivity issue, then try restoring your iPhone or iPad to factory settings via iTunes:

Connect your device to computer via original USB cable

Choose your iPhone, iPad, or iPod once it is detected in iTunes

Go to the Summary panel and hit the Restore button

Finally, click Restore again to confirm the action. Note: Restoring your iOS device will erase all user data and content, before going back to factory settings.

Downgrade iOS 9 to iOS 8.4.1

If the connectivity problems persist even after restoring your iPhone/iPad, then you can try downgrading iOS 9 back to iOS 8.4.1 using the step-by-step guide posted here.

It could be the router. I had the same problem with my iPad, which suddenly would not connect and said the password was incorrect when it wasn't. I logged into my router control panel, and the Wireless control setup. Then changed the setting of the WiFi network to None on the security options. Then logged back in with the iPad without the need for any password. That worked. Then I went back in to the Router Wireless Control and changed the Security option back to WPA2. Then logged back in to WiFi on the iPad, this time putting the password back in when prompted for it. This time it accepted the password. Bingo!

I have changed my router from 2.4Ghz network to 5Ghz network and it did connect to the network.

by

If you can it's a good idea to alter the AP names so the 2.4 & 5 GHz bands are uniquely named. I like adding the frequency to the name ACME_2-4 & ACME_5.

One last thing to check to see if your phone will connect. Disable password in your router and make it an open network and try connecting for troubleshooting purposes

iPhone 6s won’t connect to wifi, always wrong password.

So this annoying problem came to me too. I did a lot of tests The situation was

(1) My iPhone 6s could not connect to any 2.4GHz wifi. It complained always about wrong password. By any I mean all my 4 working wifi routers and all the wifi at my friends places, public libraries, train stations, airports etc.

(2) Removing password on the router just made the iPhone change the error message to “unable to connect”.

(3) When I place the iPhone just beside the antenna of the router, within 10 cm, it can connect without problem, with or without password. Tested on several different routers, also on wireless personal hotspots (tethering) from other iPhones and Androids.

This (3) was the most strange and unexplainable thing, refer to (6) and (7) below.

(4) It has no problem with 5 GHz wifi, no problem at all. Also with the same SSID and the same encryption protocol and password.

By now, it is already clear that this is not a software problem. So the next one was not necessary.

(5) Reset the phone to factory settings (or any other resets) and upgrade to newest version IOS did not change anything. Please don’t suggest resetting the router, I can’t do that for all routers in the world.

You might think that the phone must have a defect 2.4 GHz antenna. But then

(6) It could see all 2.4 GHz wifi as good as another “good” iPhone 6s could.

So receiving ability was good enough.

(7) When I set both this iPhone 6s and another good iPhone 6s as personal hotspots (tethering), both turned out to be on 2.4 GHz (You can’t on an iPhone really specify which one you want, can you? I can choose wifi band for Personal Hotspot on my Android phone), and measured the sending strength, they were exactly the same.

So sending power had no problem either.

(8) Wifi client could only connect to the personal hotspot on the good iPhone, not the defect one.

(9) Apple shop / Service Center tested the iPhone with all possible devices but could not find any problem. Well, not surprising. Although I did not have any of the equipments they had, I still think that my troubleshooting was as good as theirs.

After almost one month long struggle, Apple finally decided to replace my iPhone with a brand new one.

So conclusion: iPhone’s 2.4 wireless network can easily break down, reason unknown.

If you guys experience similar issue, and when you go to Apple shops, the phone then can connect to wifi there without problem, it’s because in Apple shops they have 5 GHz. Make them try it on 2.4 GHz wifi, and if they can’t make the phone connected, insist on having a replacement.

One solution to "wrong password" when connecting to a known wifi.

Go to router settings and check for MAC id filter.

Get the WIFI id from your iphone and enter the same in the router settings and save it.

PS: In many cases, the wifi id and the bluetooth id are almost identical except for the last digit. If already entered in the router settings recheck the id's again.

All iPads seem to do this after the iOS 10 update. To temporarily fix this toggle the airport button once or twice and then try to reconnect. iPad may continue doing this the next day but at least it connects after the toggle. The permanent fix should come with a next iOS update however even with the 6th beta of iOS 11 I have the same issue. Just crossing fingers and hoping someone takes care of it.

I found a trick to resolve this issue...all you will have to do is remove the security from you Router such as WPA or WPE and your IPAD /IPOD/ IPhone will connect to the network.

i mean remove any password that you have set for connecting to your router and make the security to NONE and it will connect.

That opens up anyone (including the creepy guy parked out on the street) to connect to the WiFi, so that they can view everything you are doing. This doesn't solve the issue, it simply removes security... which is important in this day and age.

I think this problem is related to the country and wifi channel, change the country to USA in wifi settings and set wifi channel to 11 or Auto, I think this would solve your problem

I have an iphone 7 that recently started to do this. I just found a fix.

My problem was I was finding myself able to connect to the ubiquitous unsecured xfinity network, but when trying to connect to my own network I was getting an Incorrect Password, or Unable to Join Network error message.

I tried several different solutions: rebooting the phone and the router, changing some router settings, deleting network settings on the phone, disabling wi-fi location, forgetting network. There maybe a couple of other things I tried too, but can't recall.

So what solved my issue? I switched off cellular data. Now I can connect to my home network without problem. Magically, the password suddenly works.

At first I was ticked off with Sprint for overriding my wish to connect by wifi, but after reading around a little, I feel better about this. Why? Because when cellular data is switched on, a lot of companies default the phone to use cellular data instead of wifi, even when a device is logged in to a wifi network and both are available for data transfer. In many cases the users were thinking they were connected through wifi when in fact it was cellular data and they were running up hefty bills. So on my phone (it may not be the same for others), I now know when I'm paying for cellular data (pretty much anytime it's turned on).

There are very old and extremely generic instructions provided here. For example, it hasn't been possible to downgrade iOS (especially to 8) for a very long time. All of these suggestions assume the phone is at fault. Try to power off/power on the home WiFi router, or make sure the router has the latest security updates / firmware updates. A lot of home routers suddenly freeze or partially crash when many devices are connected or too many of them are downloading at the same time.

My iPad does the same. I don’t have a permanent fix but I have completely shutdown the device and after 10 seconds turn back on. My WiFi is then connected again automatically.
