iPadOS will not take my wi-fi password

I connected mine to my macPro and put it in restore mode to re-run the update. If that doesn't work, I'll try a full DFU restore and then restore my files from my iTunes backup on my Mac.

I'll post back with my results. I guess I should have waited... :-(

Why won't you just do the erase and restore?

Your iPad Air 2 will be fine once this is done.

Many problem iPad Air 2 user with these issues have reported they went away after the erase and restore.

You just keep refusing to want to do this!

What if Apple doesn't come out with a patch for this?

Not every iPad Air 2 was adversely affected by iPadOS.

Looks like a long call with support tomorrow

Thanks for confirming @d0ug3y .. at least that'll allow us to install a further update from Apple. I also saw Bluetooth tethering works, so that's another way to get a connection.

Apple Engineering sent me an email about it & asked me to install a debug file to help analyse what's going on.. I intend to do that tonight. At least they seem to be taking this seriously.

DON'T INSTALL 13.1.1 AFTER THE BROKEN 13.1 :(

I had the same wifi problems with 13.1 - it could only connect to open wifi.

I installed the 13.1.1 update hoping it would help, and now my iPad Air 2 is stuck in a reboot loop. I'm trying to recover it now, but iTunes says it can't communicate with the ipad.

I'll update this when/if I fix it.

Same issue here. Same iPad Air 2. I installed 13.1.1 this morning (thinking that the 1.1 meant that they had already worked out the initial release bugs - wrong). I have probably spent 5-6 hours trying to sort it out. The download, prepare, verify and install went well. When I went through the "Welcome" steps and got to the "connect to the network" that's when the problem surfaced. It found my network but when I entered the network PW, it would not join (it never said "incorrect password"). I tried it repeatedly and got the same result. I tried rebooting the iPad and then connecting to my Wi-Fi network. Nada. I then went to my MBA and Keychain Access to confirm that I was using the correct network password (I was). I then posted on this community and asked how I could go back to 12.x.x and received a reply that there was no backward install and I should contact Apple. I contacted Apple Support and they had me do a Settings>General>Reset>Reset Network Settings and then tried the network connections again. Nien. I then tried to backup my iPad to my MBA via iTunes. I got the message that iTunes got an error when trying to read the iPad Air 2 and could not connect. I tried using Hotspot on my iPhone but it wouldn't connect. I tried pairing my MBA via Bluetooth to the iPad Air 2 but the MBA would say it was connected while the iPad Air 2 indicated it was still trying to pair (spinning wheel)...the the iPad Air 2 just turned off Bluetooth (all by itself) and I couldn't get it to go turn back on.

Everything else on the iPad works (unless it's something that requires a Wi-Fi connect - which is almost everything). But, the books I'm reading on the iPad are there and work.

I made an appointment with the Apple Genius Bar for tomorrow afternoon (even though its a 46 mile one-way drive). I'm just going to have them either install a working 13.1.1 or reinstall 12.x.x on it and wait for a final bug fix on 13.1.1 before reinstalling. I think the update corrupted something.

I have my MBA and my iPhone X but this thing with iPadOS 13.1.1 is a big waste of my time.

Button repaired. Reinstalled 13.1.3 and it works. Back in business.

I talked to Apple Support via chat and they are not aware of this. They ran a remote diagnostic and all looks good. I am able to join non-password protected networks, but any wifi + password is a no go. We need a fix ASAP. The support rep told me to make an appointment at the Apple Store for this issue

I am able to connect to Open Wifi - in my case Xfinity Wifi - which then opens a captive portal to which I need to login using my comcast login/pass. This proves that the Wifi chip itself works fine. Something just get messed up with password protected networks

I have the same problem and have tried "Reset All Network Settings" and that didn't work for me either...

I just upgraded to iPadOS 13 and when it tried to complete the setup and sign into my apple account, it failed and took me back to the complete setup process. I tried it a couple of times, not noticing that the WiFi wasn't working and eventually skipped the step. When I tried signing in again later, I realised my WiFi wasn't connected. First of all I tried connecting and it failed. I forgot the network and tried again. I restarted the OS and tried again, but still no joy. It was at this stage that I "Reset All Network Settings" but it made no difference. I have even tried tethering it to my iPhone and that doesn't work either.

My iPad is also an iPad Air 2 (Model MGKL2LL/A)

Exactly the same issue here too.. iPad Air 2.. now can't connect to wifi or tether to my phone's wifi hotspot (where I have a really simple password). Also tried 'Reset Network Settings', forgetting the access point, etc. Nothing has worked so far.

Same device, same problem + while I am able to join a Bluetooth personal hotspot (from my iphone), I'm not able to join a wifi personal hotspot from the same phone... then network seems to not work still... unable to authenticate my apple id.

Looks like all networking is broken!

Further to my previous post, I have just upgraded the firmware on my router which of itself kicked off a restart. I have also tried performing the "Reset All Settings" option on the iPad and that too had no positive affect on the WiFi, it just did what it said it would, reset all settings.

Unfortunately the Wife is trying to watch netflix so isn't too keen on me keep taking the router out of action so haven't tried WiFi with no authentication aka Open WiFi.

I got an email from Apple WiFi Engineering asking me to install a special profile for diagnostic and to upload the results. I ran the profile, but I can't get my iPad to sync with iTunes in order to get the logs. When I plug it the iPad and try to sync I get an error "iTunes could not connect to the iPad “iPad” because an error occurred while reading from the device." Looks like this is another bug of iPadOS 13.1

I am not ready to do a full restore yet since I did not backup my iPad in a while, so hopefully they will find a software fix to this problem soon

Thanks Sandor866, your info worked for me. Everything is working perfectly and even faster than before. My iPad Air 2 was almost unusable after the 13.1 update. No WiFi, not able to sign into iCloud or anything else that needed authorization. iTunes for Windows couldn't even connect or recognise the iPad while it was on. I had a backup on iCloud from a week ago so everything restored back to normal.
