PLEASE EXPLAIN THIS ERROR TRAPPED BY FLASH INSTALL:
"Ignoring unknown interface =."

**luther** · 04-06-2012, 07:36 PM

Hi,

Output from Mint 11 LXDE flash install:

Code:

a23@abc ~ $ sudo iwconfig 
[sudo] password for ren:  
lo        no wireless extensions. 
 
eth0      no wireless extensions. 
 
wlan0     IEEE 802.11bg  ESSID:off/any

          Encryption key:off 
          Power Management:off 
           
a23@abc ~ $

Same hardware settings, different OS.
Why can't Knoppix detect wlan0?

No idea anymore; but you can still try

Code:

hwinfo --wlan

Dear Werner:
Hopefully the last resort does the trick:

The latest clue:

Code:

knoppix@Microknoppix:~$ sudo modprobe b43
FATAL: Module b43 not found.
knoppix@Microknoppix:~$

Yet Synaptic Package Manager reports b43 installed!
Where is it hidden (screen6.jpg)?

Thanks Werner!

What's about

Driver Status: ssb is not active
Driver Activation Cmd: "modprobe ssb"

**utu** · 04-07-2012, 11:43 PM

Greetings, Werner & luther.

FWIW, on my machine with 6.7.1, hwinfo -wlan gives strange,
unuseful results relative to hwinfo --wlan.

On my machine, with 6.7.1, I get the following, which I do
find useful.

Code:

knoppix@Microknoppix:~$ sudo hwinfo --wlan | grep -i driver
  Driver: "wl"
  Driver Modules: "wl"
  Driver Info #0:
    Driver Status: ssb is not active
    Driver Activation Cmd: "modprobe ssb"
  Driver Info #1:
    Driver Status: wl is active
    Driver Activation Cmd: "modprobe wl"

In my case I need the wl driver, and here we see it's activated,
while ssb is neither used nor needed.

**luther** · 04-08-2012, 02:06 AM

Dear Werner and utu:

So I do a MC of b43 (Mint tried & true) and
use ssb? What is the logic? I would like to see
something in Synaptic Package Manager, etc.,
about ssb status?

file: "/etc/modprobe.d/broadcom-sta-common.conf" blacklist's
BOTH b43 and ssb:

# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
blacklist b44
blacklist b43legacy
blacklist b43
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
install wl /sbin/modprobe --ignore-install wl $CMDLINE_OPTS

Thanks for replying to my thread.
luther
PS. Good point to take a breather.

**luther** · 04-08-2012, 02:51 AM

Hi,
No screen dialog was observed, other than:

Code:

knoppix@Microknoppix:~$ sudo modprobe ssb
knoppix@Microknoppix:~$

I need an interpreter to utu's tip:

Code:

    knoppix@Microknoppix:~$ sudo hwinfo --wlan | grep -i driv
 info.linux.driver = 'b43-pci-bridge'
  E: DRIVER=b43-pci-bridge
  Driver Info #1:
  Driver: "b43-pci-bridge"
  Driver Modules: "ssb"
  Driver Info #0:
  Driver Status: ssb is active
  Driver Activation Cmd: "modprobe ssb"

No difference:

Code:

  knoppix@Microknoppix:~$ sudo iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

knoppix@Microknoppix:~$

luther
PS. Going on Holiday!

**utu** · 04-08-2012, 04:34 AM

I think the 4318 is a special case that uses b43 not wl as the driver.
For one person's solution, see post #13 at :
http://knoppix.net/forum/threads/286...highlight=4318

In luther's case he should probably blacklist wl & ssb.

It would be good to know for your Mint 11 install what lsmod tells us about which drivers work there.
