I created a file /etc/modprobe.d/blacklist. Contents:
blacklist bcma
blacklist ssb
blacklist b43
Use bootcodes blackist=b43 blacklist=bcma blacklist=ssb

Quote
Also, another question. The processor on this netbook is 64 bit. The wl driver is in the 3.0.3 directory, not the 3.0.3-64 directory. It seems to work, but should a 64 bit version be used instead.
It was build as a 32bit driver, if it works, then you're using 32bit

Hi juanito,

Thanks for the information. I will use the blacklist cheatcodes.

Regarding, the 64bit vs 32 bit. Interesting, perhaps the specs are misleading. See below. I will try using 32 bit versions of everything.
Using 64bit modules, the WL driver does not work acceptably. After blacklisting and modprobing as described earlier. I can find wireless networks. When I attempt to log onto my network, the pc hangs. Only recourse is to re-boot.

I have had better success using the 64bit version of Porteus. Sometimes it works perfectly. Sometimes hangs as above.

No problems using Windows 7, although I, obviously, prefer not to.

Thanks again for your help.

Best regards,

sci-fi

Using 64bit modules, the WL driver does not work acceptably.

..there are two choices with tinycore:

tinycore/microcore: uses 32bit everything
microcore64: uses 32/64bit kernel, 64bit kernel modules and 32bit everything else.

The wl extension was compiled to use with tinycore/microcore, not microcore64.

Thanks, juanito.

Everything is working when I use my own script to connect using wpa. I have trouble with wicd carried over from tc 3.8.4. Seems to connect but then hangs. If/when wicd is available on 4.x, I will try again.

Thanks again for the help. Much appreciated.

You could use the wifi.tcz extension in the meantime?

Hi juanito,

Wifi.tcz is great. Small, fast, fewer dependencies. Works fine. Thanks for the suggestion.

Hi everyone:
I cannot connect to internet via wifi.tcz either.  My netbook has a BCM4312 wi-fi card and I use a resticted wep.  Have followed all of Juanito's recommendations, but with no luck so far.  :-[

The wi-fi led is on and the modules: cfg80211, lib80211_crypt_tkip, lib80211_crypt_wep, lib80211_crypt_ccmp are loaded.

Also tried with:

sudo iwconfig eth1 essid "MYESSID" key MY_10_CHARACTER_HEX_KEY

and get the following error:

"SET Encode" (8B2A): Set failed on device eth1; Invalid argment.

the dmesg | tail -20 gives:
Code: [Select]

I used wicd in the past (tc-2.3) and had no problems.
Has anyone had the same problem before?

cefcom: I assume you are now trying it with TC 4.x. According to this advice there could be certain conflicts with your kind of hardware.

It might help if you would attach here the results of lsmod and lspci -vnn (of course that requires the installation of 'pci-utils.tcz'). Furthermore, I'm curious which exact firmware extension you've got installed.

dmesg should show whether or not the proper firmware is loaded by the driver.

Well, probably most of the time. But I'm pretty sure that I've experienced within the last 18 month at least once a situation where the fact that a firmware file was missing was not obvious (i.e. no warning in the 'dmesg' output). Unfortunately I don't recall the exact hardware combination, but I believe I ran a test with one of the more "bloated cousins" (e.g. Ubuntu, Fedora or Knoppix) and was able to identify what was wrong.

I've read this info and since my card is the BCM4312g, it is fully supported. :D

Well, 'wl.tcz' is certainly not a firmware extension, but rather contains one of the two "competing" kernel modules. The other option is AFAIK the 'b43' kernel module that should be contained in the 'wireless-KERNEL.tcz' extension.

Now, I can't quite work out whether the former extension (which you have not managed to get going) needs firmware. But I'm pretty much convinced that the 'b43' one needs the 'firmware-openfwwf.tcz' extension to be installed. Furthermore the web page I had referenced in my earlier post is AFAICT predominantly referring to 'b43' (with some information of how to change things around between the two alternatives).

I'd therefore like to suggest you read the WHOLE page really carefully (keeping in mind this issue of this unfortunate competition). Following that you might want to give the 'b43' module a try.
