TCP 5.1 Team,

It appears that there's a bug unique to tc-5x on this hardware while cutting the BCM4318 firmware:

Dear tinypoodle:

There are NO stupid questions, only answers.  All forward slashes confirmed OK.

The subject of this thread needs to be addressed by the TCP 5.1 team.  Adding TCP 4.73 to the mix adds a baseline functionality incentive for lowest common denominator resolution ASAP!
Sincerely,

No, the forward slashes are NOT OK. You have included a leading slash NOT in the instructions.
Your repeated return to your previous mistakes after things have been demonstrated as working properly will ensure that you never
will have a functioning system.

Dear tinypoodle:

Well, often you seem not to provide accurate/specific answers to what is requested from you by all those trying to support you...

Quote
All forward slashes confirmed OK.

Not sure what to make out of this, I think the request (which you even quoted!) was as simple, specific and detailed as possible, you shout "bug" every somesuch, but are not really helping if you don't follow up with further investigation.

You have been pointed to the exact same "How to" more than one year ago, in a thread in where you had similar complaints and requests and claimed similar bugs as in this one, none of which has been proven to be a bug ever since.

http://forum.tinycorelinux.net/index.php/topic,14622.msg83308.html#msg83308

So, if you claim to have found a bug in a "How to" more than one year after you have been pointed to it, while in over 3 years none of the more than 4000 users having viewed the same have reported anything, you are not convincing at all when you are not following up and provide necessary evidence.

Generally speaking, bug reports about bugs which cannot be reliably reproduced most likely end up with status "Closed. Can  not reproduce." - except in the rare case where there would be indications of a heisenbug.

This sentence leaves  me puzzled, not understanding what any of it could possibly mean...

hi,
WLAN on TCP 5.1 has never functioned properly on this hardware, only TCP 4.73/wicd has, as w/other distros.

e.g., Slackware 14.0, Porteus-XFCE 2.0

1. There is nothing specific to "WLAN on TCP 5.1" in what you quoted gerald_clark, but it's entirely specific to 'tar', i.e. how to add files to Core's backup in general.

2. Testing a specific piece of hardware with different distros could only provide for anecdotal evidence.

My anecdotal evidence with testing a specific wireless radio with dozens of distros over a timespan of many years has shown that it would only ever work out of the box under CorePlus and Slackware 9.0, while OTOH it took me 2 hours of fiddling under Ubuntu and I gave up after a few days of trying with Backtrack (oh the irony!).

Maybe it's time to re-state what you'd like to achieve.

I understand you'd like to get wifi working with your bcm-4318 hardware using an installed x86 tc-5.x, but is your aim to have it working from the cli, with the wifi extension or with the wcid extension?

In addition, do you wish it to work with freely available firmware or with the broadcom firmware as described in linux wireless b43?

Dear Juanito:
No bloat means CLI.  I have NO faith in wifi extension w/WEP and wicd extension has too much bloat to pursue any 5.1 usage.  You enlightened me on this WLAN CLI indexing avenue that thread feedback shows optimism.  Also, going with a frugal install to thumb drive w/no wifi/firmware installation.  Just add the essentials one by one.

Hindsight is twenty-twenty, so whatever was used successfully w/TCP 4.73, I'm for, where b43-fwcutter was ignored.

So:

* boot tc-5.x with no firmware/wireless extensions "onboot" and no wireless modules blacklisted.
* load firmware-openfwwf extension
* load wireless-KERNEL extension
* check dmesg to see if b43 module has loaded and found the firmware it requires

paste relevant dmesg output here

OK, that looks OK (except I might have expected to see "wlan0 somewhere), now I guess you can try:
Code: [Select]
$ sudo iwconfig wlan0 essid "eltonenetwork"
$ sudo iwconfig wlan0 key 6789abcdef
$ sudo udhcpc -b -i wlan0 -x hostname:box -p /var/run/udhcpc.wlan0.pid

BTW, "lsmod" is OK, "sudo lsmod" is not required.

hi,
CLI line one is missing a component:

Code: [Select]
tc@box:~$ tce-load -i firmware-openfwwf
/etc/sysconfig/tcedir/optional/firmware-openfwwf.tcz: OK
tc@box:~$ tce-load -i wireless-3.8.13-tinycore
/etc/sysconfig/tcedir/optional/wireless-3.8.13-tinycore.tcz: OK
tc@box:~$ sudo iwconfig wlan0 essid "eltonenetwork"
sudo: iwconfig: command not found
tc@box:~$


Suspect there's a better firmware choice w/missing component.
