reboot your machine without any firmware or wireless extensions loaded

cut and install the b43 firmware as detailed above

load the wireless-KERNEL extension

paste the results of "dmesg | tail -20" or similar

Dear Juanito:

I had important business interrupt solving this problem, so machine was shut down following previous post.

Now, paste data following reboot:


--- Code: ---tc@box:~$ dmesg
mitc@box:~$ crocode: AMD CPU family 0xf not supported
8139too 0000:06:06.0 eth0: link up, 100Mbps, full-duplex, lpa 0x41E1

tc@box:~$


--- End code ---

The cut/install firmware step appears transient.

Q: How can all this be made persistant, so it eliminates manual setup following every reboot?

Sincerely,
eltone

You need to make an extension out of it or add the b43 directory to your /opt/.filetool.lst and do a backup.

hi,

Followed #28 recipe that resulted in the following wifi dialog:


--- Quote ---wlan0 interface doesn't support scanning

--- End quote ---

This dialog then vanishes!  It is much too early to consider another b43 extension/backup, etc.  Wifi previously controlled the hardware LED and suspect missing dependencies remain.

I usually see something like this when the wifi hardware switch on my laptop is set "off".

I copied the rfkill extension to the 5.x repo, could you check that you get something like this:
--- Code: ---$ rfkill list wifi
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: brcmwl-0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
--- End code ---

I no longer have hardware that uses b43, but using my laptop with both ndiswrapper and wl-modules-KERNEL, the hardware LED comes on when the driver is loaded.

hi,

For comparison, I just loaded the  TCP 5.1 LiveUSB onto my vintage 1998 hp desktop, w/256MB RAM:

The WLAN chipset is RTL8185L, mdl # TL-WN353G, PCI adapter w/NO hardware switch.


The same error is trapped on this machine:

Suspect bug in scan lib . . .
