[arch-general] netcfg drops wifi connection

[Arch Zealot]

Every time i connect to a wireless network (no matter how strong the signal is), after 1-2 minutes, the connection is dropped and i have to manually start it again. This never happens with the ethernet connection.


I'm currently testing this with a WEP connection using wifi-menu to connect to an already created profile (netcfg version 3). I have Arch x86-64 with a Broadcom  BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) wireless card and use the b43 driver from AUR.

On connect this is the dmesg:

b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07) 
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready 
b43-phy0: Loading firmware version 666.2 (2011-02-23 01:15:07)

wlan0: authenticated 
b43 ssb0:0: wlan0: disabling HT due to WEP/TKIP use

wlan0: RX AssocResp from 08:76:ff:3f:8b:90 (capab=0x411 status=0 aid=2) 
IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready 
wlan0: associated

On connect this is the output from wpa_cli status:

bssid=08:76:ff:3f:8b:90 
ssid=xxx
id=0 
mode=station 
pairwise_cipher=WEP-40

key_mgmt=NONE 
wpa_state=COMPLETED 
ip_address=192.168.1.67 
address=70:1a:04:f0:2a:bd 


After disconnection, this is from dmesg:

ieee80211 phy0: wlan0: No probe response from AP 08:76:ff:3f:8b:90 after 500ms, disconnecting. 
cfg80211: Calling CRDA to update world regulatory domain 
wlan0: authenticate with 08:76:ff:3f:8b:90 
wlan0: send auth to 08:76:ff:3f:8b:90 (try 1/3) 
wlan0: send auth to 08:76:ff:3f:8b:90 (try 2/3) 
wlan0: send auth to 08:76:ff:3f:8b:90 (try 3/3) 
wlan0: authentication with 08:76:ff:3f:8b:90 timed out 

The last 5 lines from dmesg keep repeating a few times more.

After disconnection, this is from wpa_cli status:

<3>CTRL-EVENT-DISCONNECTED bssid=08:76:ff:3f:8b:90 reason=4 
<3>CTRL-EVENT-SCAN-RESULTS  
<3>WPS-AP-AVAILABLE  
<3>SME: Trying to authenticate with 08:76:ff:3f:8b:90 (SSID='xxx' freq=2412 MHz) 

These lines keep repeating a few times too.



Please advise!
