Thanks fanthom.

Do you see anything I need to blacklist?

from the lspci output we can see that your wifi chipset is identified as [14e4:4727]:

Code: Select all

02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
now you go to:
http://wireless.kernel.org/en/users/Dri ... ed_devices
and can find that this device is supported by 'wl' and 'brcm80211' drivers. 'wl' doesnt work (otherwise you would have internet already) so we need to blacklist it and un-blacklist the rest. please save following code as /porteus/rootcopy/etc/modprobe.d/b43_blacklist.conf:

Code: Select all

blacklist wl
the last step is to get brcm firmware so your brcmsmac driver can work. please download kernel firmware package from here:
http://ftp.heanet.ie/mirrors/ftp.slackw ... arch-1.txz
and copy /lib/firmware/brcm folder to /porteus/rootcopy/lib/firmware/ and you should be good to go.
Please add [Solved] to your thread title if the solution was found.

Yes.

And in the examples at your viewtopic.php?f=39&t=1099 link you show lspci -knn commands that show:

Code: Select all

Kernel modules: wl, ssb
and

Code: Select all

Kernel driver in use: wl
Kernel modules: wl, ssb
My lspci -knn command doesn't show those relationships.
now you go to:
http://wireless.kernel.org/en/users/Dri ... ed_devices

Ok. Will try this next time I boot the flash drive. Will I need to do anything to activate the non-blacklisted drivers?
the last step is to get brcm firmware so your brcmsmac driver can work. please download kernel firmware package from here:
http://ftp.heanet.ie/mirrors/ftp.slackw ... arch-1.txz
and copy /lib/firmware/brcm folder to /porteus/rootcopy/lib/firmware/ and you should be good to go.
Now I was going to say that I can't do this because I'm booting an ISO but that's incorrect. The USB flash drive is not booting an ISO is it. So that means if I don't boot it into Fresh mode changes will stick. And if I reboot into Fresh mode these changes will still be there, right? So the only concern then is if I recreate the flash drive. Cool.

On the flash driver's 2nd partition's I only have an empty /porteus/rootcopy/ folder. No /porteus/rootcopy/etc/modprobe.d/ no /porteus/rootcopy/lib/firmware/. Should I create these folders when adding these files?
