Re: TCP 5.1 LiveUSB
BCM4318 WLAN chipset

Hi,

I just did a fresh TCP 5.1 install.

WiFi cannot scan/find cells:

This problem appears to be a carrie-over from TCP 4.73, where the work-around was to use
wicd network manager and rfkill.

Q: Is there a fix coming?

Also, wicd and rfkill needs to be TCP 5.1 recompiled.

Kind Regards,
eltone

Juanito:
There's nothing in your dmesg that indicates a problem with rfkill, or any other problem with wifi.

Adjustments were made to the base for tc-5.x to change the rfkill permissions - could you confirm that your wireless does not work with the wifi extension (tested with your wired connection disconnected/disabled).

Dear Juanito:

Without wired ethernet, clicking the Wbar wifi icon:

*****************
Please note that wifi extension did find one cell yesterday that I did not recognize, while there are many in the vacinity.  Also, the hp dv8000 WLAN LED does get enabled and turned off w/wifi extension.

Q: Any plans to add wicd extension to TCP 5.1?

Sincerely,
eltone

Honestly I'm not sure why you'd blacklist wl proprietary driver if you are using the in-tree b43 driver with bcma and ssb ??   possibly bmca doesn't need to be blacklisted either

Given this I'd say that the driver b43 is loaded, but no mention of the firmware?
I'd start over, uninstall the wl-modules if installed and remove all the unnecessary blacklist boot codes

blacklist=wl  (is this proprietary module installed?)
blacklist=bcma  (first try with this and ssb modules and firmware loaded)


Am curious of the reasons for these boot codes?

I have always used 'modprobe -r wl' in the past, but not 'modprobe -r bmca'

The two firmware extensions required for the BCM4318 chipset appear to be bundled w/TCP 5.1
b43-fwcutter.tcz
firmware-openfwwf.tcz

Q: Please list all WLAN modules required for the BCM4318 chipset?
All others should be removed!

I'm not sure about 'bcma' but 'wl' must be blacklisted when using b43 and ssb kernel modules.

This was used to add TCP 5.1 LiveUSB stability between two computers.  It shouldn't effect wifi's ability to scan for cells.
