I cannot connect to my campus Wi-Fi connection through Ubuntu 13.04 but I can do the same through Windows.

[ 1293.944518] wlan0: authenticate with 00:1a:1e:d5:f0:30
[ 1293.953216] wlan0: send auth to 00:1a:1e:d5:f0:30 (try 1/3)
[ 1294.154557] wlan0: send auth to 00:1a:1e:d5:f0:30 (try 2/3)
[ 1294.358428] wlan0: send auth to 00:1a:1e:d5:f0:30 (try 3/3)
[ 1294.562357] wlan0: authentication with 00:1a:1e:d5:f0:30 timed out

The same thing keeps occurring.

I had the same problem, but I found a solution in this bug report:

Removing "system-ca-certs=true" from /etc/NetworkManager/system-connections may solve your problem.

In Ubuntu 16.04 LTS:

  1. Click on the Wi-Fi icon on the rigth corner and click "Edit Connections..."
  2. Select your Wi-Fi network (eduroam) and click "Edit"
  3. Click "Wi-Fi Security" tab
  4. Set Authentication to "Protected EAP (PEAP)"
  5. Tick "No CA certificate is required"
  6. Set PEAP Version to "Automatic"
  7. Set Inner Authentication to "MSCHAPv2"
  8. Type your username and password
  9. Click "Save"

You should be able to connect now. Editing the file in system-connections folder did not work for me.

I noticed that there aren't any lines like system-ca-certs=true in /etc/NetworkManager/system-connections/<SSID>, so I resolved in this way:

  1. Turn off WiFi
  2. Add on a new line system-ca-certs=false
  3. Turn on WiFi (the line will be deleted automatically)

I had the same problem connecting to my university wifi. If disabling system-ca-certs doesn't work for you, try downgrading wpasupplicant.

If ur on ubuntu, you can downgrade to wpasupplicant 2.9.0 build 1 using:

sudo cat <<'EOF' | sudo tee /etc/apt/sources.list.d/impish.list
     deb http://archive.ubuntu.com/ubuntu/ impish main restricted universe multiverse
     deb http://archive.ubuntu.com/ubuntu/ impish-updates main restricted universe multiverse
     deb http://archive.ubuntu.com/ubuntu/ impish-security main restricted universe multiverse
     EOF
sudo apt update
sudo apt -y --allow-downgrades install wpasupplicant=2:2.9.0-21build1
sudo apt-mark hold wpasupplicant

If this works for u, all credits go to my seniors who posted this on our Foss club discord server.
