Title:
wifi connection drop (b43 eapol timeout)
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Experiencing problems with a BMC4331 wlan chip controlled by the b43
kernel driver with the following environment:
- Stock raring with b43 wifi driver on a 3.0.8-31 generic kernel on a Macbook
Pro 8,1 (although this problem has been around since kernel version 3.2),
- Router is a D-Link 625 with Openwrt Attitude Adjustment (12.09, r36008),
- Wireless cell is 2.4 GHz with WPA2 PSK authentication.
The symptoms:
- Openwrt hostapd issues a WPA rekeying request for the group temporal key
(GTK),
- B43 / wpa_supplicant times out (the router log showing a "EAPOL-Key
timeout" error message),
- Openwrt issues another GTK handshake message,
- The sequence repeats four times after which the router unauthorises the Mac,
- Ubuntu drops the connection and wpa_supplicant initiates a
re-authentication sequence after a while.
I have a pretty good idea of what's happening on the router side, but
fail to increase the logging level of wpa_supplicant on the Mac.
"wpa_cli level" rejects any attempts to increase the level from
"msgdump" to "excessive" so I am at a loss why wpa_supplicant / b43
fails to acknowledge the GTK re-keying request (the b43 module
debugging is already turned on).
First step would be to convince the running wpa_supplicant instance to
generate more debugging information to see why the request is not
answered. Happy to provide more information once this is achieved.
