Question Can't connect to university 802.1x WiFi

bomberb17 · Jan 28, 2022

I am running official MIUI Global 12.5.4 ROM (the only thing is that I am rooted, and always have been rooted).
But I noticed that for a month or so, I can't connect to my university's enterprise WiFi. It used to connect fine before, maybe this is related to the new ROM but I am not 100% sure. My phone connects to my home WPA2 WiFi normally, as well as other open networks.
What happens is when I tap on the Wifi network it shows "connecting" then it stops and does not connect.
The problem is of course not on the university's end, because my other laptops, devices etc. connect as normal.
Is there a way to troubleshoot or solve this without "aggressive" things like wiping etc. ?

i don't know if my case is the same but... Wi-Fi from a Private University of here can connect correctly (yes , it's a enterprise too)
i'm running MIUI 12.5.4 Global UnRooted...

To add, I've tried forgetting the wifi network and re-configuring the wifi settings, same results. Any good apps that might be helpful to solve the problem? (i.e. show logs why connection is rejected?)

You can try to see if you can debug the problem running

Bash:

adb logcat wpa_supplicant:V *:S

or using an app like MatLog and filtering with wpa_supplicant.

Hopefully you'll have some more clues on what's the problem and you can search for a solution.

I used Logcat reader with root privileges, here is a copy of the log when I attempted to connect to the "eduroam" wifi network:

I'm looking at that error:

Code:

Received abnormal flag string: [WPA2-EAP-CCMP][RSN-EAP-CCMP][ESS]

Not sure if this is the only one I should be looking at. I found someone who had a similar problem a few years ago with a different phone, but no suggested solution

Can't connect to WIFI after V11.0.4.0 update - Mi 9/SE/T/T Pro/Lite - Xiaomi Community - Xiaomi

c.mi.com

MrCrayon · Jan 29, 2022

I don't really know what I'm talking about but if I had to guess it looks like it's trying to authenticate with the wrong protocol.

I also found this but not sure if it's related

Android 11 will no longer let you connect to some enterprise WiFi networks

The Android 11 update will break connecting to certain enterprise WiFi networks. Here's why and what you can do to fix it.

www.xda-developers.com

P.S.
You could try to enable Wi-Fi verbose logging in developers options to see if you have more details. (remember to turn it off when you are done)

bomberb17 · Jan 30, 2022

So after I enable verbose logging, how do I see the log? Again using a third-party app?

Same as what you used before.

bomberb17 · Feb 3, 2022

Ok so here is a paste of the verbose log. I tried to connect to Wifi "eduroam" three times during logging. I can't pinpoint where the issue lies now though.

<<< log_count = 3287 >>>[02-03 09:26:30.712 1838:2349 D/MIUIInput][MotionEve - Pastebin.com

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.

pastebin.com

I also tried to connect to another enterprise network by another organization, and I am having the same issues. So my device basically cannot connect to enterprise wifi networks.

MrCrayon · Feb 4, 2022

I am no expert but I think it might be related to the article I posted before.
Do your WIFI setting require to select "Do not validate" for CA certificate?
If so is that option still available?

BTW I can see your email in the log you posted, you might want to scan for other personal info or just delete the log, I don't think I can find anything anyway.

bomberb17 · Feb 7, 2022

Thank you for the heads up, yes I removed my email.

The wifi network is basically the "eduroam" network which is used across universities worldwide. The instructions posted by my university do not have any requirement to select "Do not validate", although in the advanced wifi settings, that option is selected.

I also tried to delete all certificates installed, and same thing happens.

Maybe this can help

I forgetted the wifi network multiple times and tried over and over again.
Also installed the latest global stable ROM which was made available a few weeks ago, same exact behavior.
Eduroam app did not help.
A couple of more clues:

1. I contacted the IT department, they say that they don't see my device MAC address attempting to make a connection.
2. I tried to connect by putting a wrong username/password on purpose. The behavior is identical, meaning my phone does not even try to authenticate in the enterprise WiFi.

Any help with this matter appreciated.

Does the phone show its identifying information (IMEI, device name) in the settings?

That would be explained by the fact that your phone and access point are not agreeing on the protocol to use to communicate so there is no attempt to login.
Maybe show them your logs I don't really have any other idea.

If you mean About phone -> All specs -> Status then yes..

Not sure if the source of your issue is the same than yours, but I had issues trying to reconnect not connecting for first time, but every time I leave it out and coming back to it, and the solution was in Network details/Privacy, changing to Device MAC instead of randomize MAC.

I have tried with randomized MAC and same thing happens..

How I fixed it, was the other way around, forgetting the connection (just one time), setting it up, and then using device MAC instead of randomize MAC (I guess this is set by default), also checking Auto connect and detect automatically. Some private connections require some additional step, logging into an account or adding the device through a QR code (you should ask for it).
