Cannot re-connect to PEAP wifi in Mint 17

Post by hlancaster »

OS: Linux Mint 17
Computer: Lenovo Carbon X1 2014

Issue:
I'm on a university campus with a PEAP/MSCHAPv2 wireless network. The first time I connect to the network, if I use the right settings, it will work. However if I disconnect for any reason (like close laptop lid and stand it by) when I try to reconnect to the network, it won't work. It's like the OS doesn't even try. As soon as I click on the SSID to reconnect, mint immediately says "Disconnected." It never says "connecting..." or shows any signs of attempting to connect to the network.

Now, if I forget the network and connect again and type in all of the settings, the computer will connect successfully. But I have to do this every time I want to reconnect. It's as if the OS has trouble saving or applying the connection settings. Any thoughts? I've tried the solutions presented here: http://forum.linuxmint.com/viewtopic.php?f=29&t=23893 to no avail.


TLDR: I can't reconnect to my university's PEAP network without forgetting the network and typing in all of the settings again. Linux Mint 17 on Lenovo X1 Carbon.


Thank you for your help!! I greatly appreciate it :)


These are the connection settings I'm using:
Security: WPA & WPA2 Enterprise
Authentication: Protected EAP (PEAP)
CA Certificate: none
PEAP version: Automatic
Inner authentication: MSCHAPv2
Username
Password

This is the output of mintWifi when I'm trying to reconnect to the network but I can't:

In the last post of that topic, it says to comment out the system certs = true, remove the # from the line and change true to false and see if it works

Hey, JeremyB, thanks for your help! That's a clever suggestion. I just tried it but unfortunately it didn't fix the problem :( Thank you though!

Thanks again, JeremyB! I've been on that bug report and tried the solutions there. According to post #162 that bug has been fixed in LM17 as well as in Ubuntu 14.04 as of July 2014. I think I'm encountering a related but different bug.

Code: Select all

uname -r
The most recent kernel for Mint 17/Ubuntu 14.04 is 3.13.0-35, if you still have -24 you might not have the fix. To update, go to Update Manager or use

Code: Select all

gksudo mintupdate
in terminal, then click on View and then Linux Kernels. Then click on install under the 3.13.0-35 and after it is done reboot.

There is a warning on the page about updating kernels but I have yet to have a kernel update destroy anything, I have had kernel updates that wouldn't boot but it was a simple fix

Thank you! I'm at 3.13.0-24-generic. I'll give the update a try later today. Thanks again, JeremyB for keeping with me on this one.

I updated the kernel to 3.13.0-35-generic and confirmed it with 'uname-r.' Unfortunately the issue persists :/ Any ideas?
