Oddities in linux client tools/views/joining-of--a.1x network

Reported by: morrowc@… Owned by: chelliot@…

In attempting to join the network today I noticed that while the ietf.1x network seemed to work fine I was unable to join the ietf-a.1x network. Looking at iwconfig output:

ietf-a.1x attempts:
wlan0 IEEE 802.11abgn ESSID:"f2\x0D\xB71X\xA3Z%]\x05\x17X\xE9\xD4\xAB\xB2\

Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off

ietf.1x attempts:
wlan0 IEEE 802.11abgn ESSID:"ietf.1x"

Mode:Managed Frequency:2.412 GHz Access Point: 00:17:DF:AA:41:04
Bit Rate=24 Mb/s Tx-Power=14 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=52/70 Signal level=-58 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

clearly something got munged badly in the (and gets munged badly everytime today for -a.1x) in the ESSID interpretation.

(if I can get a phone/data sim I'll come to the noc and we can troubleshoot)

and I'm using fedora 12/networkmanager portal-a in Berlin and I lose my connection
over and over. Lose v6 first, then total connection.

Please do come down to the NOC. We continue to investigate the issue with Linux. I should be here all afternoon.

This may be a linux kernel issue. I've found the following:

There's a note early in the first one that suggests:

"I "solved" this by compiling the bleeding-edge compat-wireless drivers from Have a look at for instructions."
