WiFi does not connect to WPA2-Enterprise network with TTLS and PAP auth

[Max]

Bug report:
Attempting to connect to the campus WiFi network under a clean install of Ubuntu 13.10 fails.
The network environment is set up using WPA2-Enterprise with TTLS and PAP authentication.
There is no CA certificate for clients to install, students and faculty are instructed to set their hardware to ignore the nonexistence of a CA cert.

My hardware is a Lenovo G780, the internal network card is a Broadcom BCM4313
I get the same behavior using a USB WiFi dongle by Belkin that I've had working on Ubuntu previous, so it's not just the Broadcom card giving the issue.

Probably important:
++ On this same hardware running Ubuntu 12.04, I could connect to the campus WiFi network.
++ Checking the system logs, I can verify that the WiFi card is associating with the access point for the network. It fails somewhere during authentication.
++ I have the same behavior with a USB WiFi dongle known to work with Ubuntu - that's a belkin that I've got to work on plenty of other setups. I'm pretty sure it's NetworkManager with the error since the same behavior happens on the Broadcom internal chip on my laptop, and the Belkin WiFi USB dongle.

The attachment WifiSyslog.txt that was automatically added to this bug report doesn't appear to demonstrate the bug. The connection log doesn't have any attempts to get onto the campus network in it. If someone wants it, I will post a better log example with a connection attempt to the campus net.

Status changed to 'Confirmed' because the bug affects multiple users.

I might be experiencing the same issue while trying to connect to eduroam (TTLS / PAP with no certificate).
I'm running kubuntu and tried kde and gnome nm applet, both failed to connect.

Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)

Until this bug is fixed, here is what you have to do in order to connect to your ttls/pap wifi network :

- disable network management
- create wpa_supplicant.conf containing :
ctrl_interface=/var/run/wpa_supplicant
#ctrl_interface_group=wheel.
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={

ssid="eduroam"
proto=WPA2 WPA
scan_ssid=1
key_mgmt=WPA-EAP
pairwise=CCMP TKIP
group=CCMP TKIP
eap=TTLS
#ca_cert="supply it and uncomment this line if you have it"
anonymous_identity="your anonymous identity (CHANGE THIS)"
phase2="auth=PAP"

identity="your login (CHANGE THIS)"
password="your password (CHANGE THIS)"
}

- don't forget to change anonymous_identity, identify and password
- sudo rfkill unblock all ("sudo rfkill unblock wifi" might work as well)
- sudo wpa_supplicant -i wlan0 -D wext -c /etc/wpa_supplicant.conf -d
- sudo dhclient wlan0

[edit last comment]
wpa_supplicant.conf must be created in /etc/wpa_supplicant.conf
You'll also need to change "ssid=" to your wifi network ssid in /etc/wpa_supplicant.conf

I'd been having trouble connecting to our campus WPA2-Enterprise (EAP/PEAP) WiFi network using Ubuntu 13.10. The workaround here [1, 2] worked for me--thanks for sharing @pfoo.

In addition, this [3] thread helped me understand what was going on.

This bug seems to be fixed in kubuntu Trusty/14.04

[Max (mattrulz127)]

As of last week, the bug was not fixed in Ubuntu 14.04 x64, at least for
me. I can't test it anymore though, since I'm not on campus for the summer.
Good to know Kubuntu works though!
