1. Nothing can be said about that trace without seeing the preceding lines.
2. I suggest you add boot code
Code: [Select]
syslog and then post or attach /var/log/messages
3. There is no sense in running udhcpc without first being associated with AP which could be checked e.g. with
Code: [Select]
iwconfig

It appears like the kernel spits out a warning and call trace when udhcpc is executed while expected firmware is missing.

That looks wrong, possibly caused by missing firmware.

Hey tinypoodle!

Those instructions have nothing etched-in-stone for TCP 5.1.

Dry run:

Code: [Select]
$ wget -c http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2
$ tar xf broadcom-wl-5.100.138.tar.bz2
$ sudo mkdir -p /usr/local/lib/firmware
$ tce-load -i b43-fwcutter
$ sudo b43-fwcutter -w /usr/local/lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o


No firmware cutting was required w/TCP 4.73.  'b43-tools' had a script to install it automatically.

PHEW!!
 ;D

Does Tx-Power still after 0 dBm after connection has become fully functional?

Also, are you sure you want 4 DNS resolver entries?

tinypoodle,

WLAN burn-in appears more stable than the hard wired ethernet connection!

If it works, don't fix it, but why question the DNS?

Now that looks all perfect, I would guess the interface was not up before you ran udhcpc, making for the difference in output.

Such a DNS mix is just not very common, but if that's how you want it and are aware of the potential consequences, ok.

Now that wicd.tcz has completed the burn-in phase on tc-4.73, it will be installed on tc-5.10 next go-around:
...
Q: Shouldn't it be recompiled first?
We'll know that once you've tested it  :P

hi,
wicd tested OK on TCP 5.1 today.  The only problem was that the firmware has to be reinstalled following each boot!

Apparently the driver gets loaded before the firmware folder is restored during the boot phase.

Remember that extension deps are recursive, there is no need to have most of those extensions named in onboot.lst

It would be better to make a personal extension out of a large amount of static data like the b43 firmware rather than making it part of your backup.

Once you've made a personal extension out of the b43 firmware, you can place it before wicd in onboot.lst
