Public bug reported:
Binary package hint: network-manager
My university's wireless access points are set to output Cisco-
proprietary configuration information in their beacon packets, namely
"wme_ie". They *should* be outputting RSN IE or WPA IE instead, but
there's not much I can do about that aside from begging and pleading
with my university not to continue to be jerks to the non-Windows-using
community.
The Ubuntu side, however, can do something about it. Attached is the
iwlist scan output from each of my wireless cards (dwl-g650 and
ipw2100). You can plainly see a properly configged WPA AP and then the
UI-Wireless-WEP WPA which has an Extra string.
The solution is to do one or both of the following:
1) Have network-manager look for the wme_ie and understand it
2) Have the wireless card drivers convert wme_ie to rsn/wpa ie
The problem with 1 is that my ipw2100 card does not pass ANY IE up to
the higher layers (at least, it's not reported in iwlist). The madwifi-
ng card, on the other hand, passes this information on to
NetworkManager, which doesn't know what to do with it.
SYMPTOMS:
The WPA network is not detected as such. Consequently, when clicking on the
network in the GNOME NetworkManager applet, you are only presented with two
options for security: WEP and open.
** Affects: network-manager (Ubuntu)
Importance: Undecided
Status: Unconfirmed
--
NetworkManager does not play nicely with Cisco wireless APs due to wme_ie being
broadcast instead of rsn_ie and/or wma_ie
