# Ubuntu – Can’t connect to WPA2 Enterprise PEAP network

16.04network-managernetworkingwpa2

I know there are about a dozen other questions like this, but so far none have helped me.

My school uses a WPA2 Enterprise PEAP/MSCHAPv2 network without a cert(which I determined from a windows laptop that connected without an issue). I'm trying to connect with my Ubuntu 16.04 LTS machine (which is pretty much a fresh installation).

Unfortunately, it is unsuccessful. It tries to connect for a while, then brings up a username/password reentry dialogue. If you hit submit on this, it simply fails again and brings it back up.

The following shows the settings and the message that keeps coming up:

The following is the /etc/NetworkManager/system-connections/ entry:

I've read in many places that adding system-ca-certs=false fixes it, but that didn't work. I also tried adding the domain Domain\username but that didn't work. I've tried everything here and in many other posts. Not sure what to do, I'm new to Linux. Any help is greatly apreciated, if there is some other info I should include please let me know. Thanks!

note: I can't obtain a certificate because I seriously doubt I'll be able to contact someone who'd give me one (as I am a student). Not to mention, I don't think they'd be familiar with a Linux based system as the school issued computers are Windows 10.

edit:
I read a lot that the problem was caused by Wpasupplicant 2.4. So, I tried downgrading to 2.1. This actually worked* when I restarted, but after a while disconnected and I couldn't get it to connect again. I even tried reinstalling wpasupplicant 2.1 but it still wouldn't connect. I'm not sure what all that implies, but at least I know that my laptop is capable of connecting to this network and I have the correct security settings/credentials.

*= the connection lasted for aprox. 10 minutes, and was much slower then it should've been. My windows laptop got 60 mbps download while this one got only 15 mbps. Granted however, Windows laptop is 2-3 years newer.

edit 2: My network card in the Ubuntu machine is a Centrino n 1000 Condor Peak from Intel. I'll gather more information on it when I get a chance.

Here is my NetworkManager log https://drive.google.com/file/d/0Bwv36xPVuImIdHQ3bjZvc25SNjg/view?usp=sharing

Here is my /var/log/syslog log

The relevant portion of both seems to be:

I can test mon-thurs since I'm near the network on those days.

This solved my problem (from here).
