I can at least partially confirm Dan's comments from 9 March:
"It looks like you're probably dealing with a driver issue. Your
iwconfig output doesn't show any link quality or even a signal/noise
level when you're connected to your network."
I'm on a Dell Latitude D830, with Broadcom 4312 wireless:
% lspci -vv | grep Broadcom
09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5755M Gigabit
Ethernet PCI Express (rev 02)
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
On boot, wicd runs and connects to my AP, then flaps (drops association,
reconnects, wash rinse repeat). If I stop the wicd daemon while it's
connected, the connection stays up.
My iwconfig output initially does not report signal strength:
% sudo iwconfig eth1
eth1 IEEE 802.11bg ESSID:"***" Nickname:""
Mode:Managed Frequency:2.462 GHz Access Point: ***
Bit Rate=54 Mb/s Tx-Power:32 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Managementmode:All packets received
Yet a few minutes later I get:
% sudo iwconfig eth1
eth1 IEEE 802.11bg ESSID:"***" Nickname:""
Mode:Managed Frequency:2.462 GHz Access Point: ***
Bit Rate=54 Mb/s Tx-Power:32 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Managementmode:All packets received
Link Quality=5/5 Signal level=-50 dBm Noise level=-91 dBm
Rx invalid nwid:0 Rx invalid crypt:1 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
So something is not totally broken / incapable of reporting this info,
just flaky.
I'll see if I can get more data from /proc/net/wireless etc. -- any
suggestions on what to look for?
