Connecting to WPA2-PEAP

[bleedingsamurai]

I have a system that I'm trying to connect to a wireless network protected with WPA2-PEAP and every time I get a "Bad Password" error from wicd and NetworkManager (neither where installed at the same time!)

I'm sure it isn't a problem with the driver, I can connect to WPA2-home, WEP, and Open networks just fine. And it isn't the wireless network per say, several other devices connect without issue, each running Android, iOS, Windows NT, and OS X

I have revisited the possibility of me mistyping my username and password several times, this is not the issue, nor is a corrupt LDAP user object.

As the Arch Linux wiki suggested, I tried using GTC instead of standard WPA2-PEAP, this did not work either.

Right now the only thing I can think of is that because the network is using a self-signed certificate, my laptop is dropping the connection as soon as it is established which would account for the "local choice, reason 3" in my dmesg output.

Also, you will notice in my lsmod output that the Intel wireless driver "is not loaded" this is because I have statically compiled it into my kernel binary.

I googled this, and a few people reported they found instances of wpa_supplicant running; when they killed wpa_supplicant the problem went away.

[bleedingsamurai]

Interesting, I'll have to double check that the next time I try to connect to this network.

Correct me if I'm wrong, but isn't wpa_supplicant needed for the kind of wireless connection I'm trying to make?

[hagfish52]

Not necessarily. I don't know what you are using for wireless management, but wpa_supplicant is an alternative to Network Manager or Xsupplicant, so if two of the programs are running at the same time they can interfere with one another.

[EDIT]

I see you are using Network Manager. Network Manager uses wpa_supplicant. In this case you want to check for multiple instances of the wpa_supplicant daemon.

You may also want to consider using Xsupplicant instead of Network Manager; it supports many EAP types.
