What does lspci -nn -d 14e4: show? (run in a konsole)

[Fintan]

Not much:

roger1@roger1-E720:~$ lspci -nn -d 14e4
lspci: -d: ':' expected
roger1@roger1-E720:~$ lspci -d -nn 14e4
lspci: -d: ':' expected
roger1@roger1-E720:~$ lspci -nn 14e4 -d
lspci: option requires an argument -- 'd'
Usage: lspci [<switches>]

Basic display modes:
-mm Produce machine-readable output (single -m for an obsolete format)
-t Show bus tree

Display options:
-v Be verbose (-vv for very verbose)
-k Show kernel drivers handling each device
-x Show hex-dump of the standard part of the config space
-xxx Show hex-dump of the whole config space (dangerous; root only)
-xxxx Show hex-dump of the 4096-byte extended config space (root only)
-b Bus-centric view (addresses and IRQ's as seen by the bus)
-D Always show domain numbers

Resolving of device ID's to names:
-n Show numeric ID's
-nn Show both textual and numeric ID's (names & numbers)
-q Query the PCI ID database for unknown ID's via DNS
-qq As above, but re-query locally cached entries
-Q Query the PCI ID database for all ID's via DNS

Selection of devices:
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]] Show only devices in selected slots
-d [<vendor>]:[<device>][:<class>] Show only devices with specified ID's

Other options:
-i <file> Use specified ID database instead of /usr/share/misc/pci.ids.gz
-p <file> Look up kernel modules in a given file instead of default modules.pcimap
-M Enable `bus mapping' mode (dangerous; root only)

PCI access options:
-A <method> Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val> Set PCI access parameter (see `-O help' for a list)
-G Enable PCI access debugging
-H <mode> Use direct hardware access (<mode> = 1 or 2)
-F <file> Read PCI configuration dump from a given file

Edit:
Using the -k option it tells me that the kernel drive in use is: b43-pci-bridge and kernel module is: ssb

Does that help?

You could do:
sudo apt-get install firmware-b43-installer


Or, run
sudo ubuntu-drivers list

to see what BCM drivers are available on your system, if any. I doubt you will find the 4312 driver because it is legacy.

The command includes the colon at the end.

lspci -nn -d 14e4:

roger1@roger1-E720:~$ lspci -nn -d 14E4:

http://wireless.kernel.org/en/users/...devicefirmware

gives: topic does not exist yet....LOL

Should I try one of these:
firmware-b43-lpphy-installer_015-9_all.deb

or


firmware-b43-installer_015-9_all.deb
?

The latter; firmware-b43-installer_015-9_all.deb

[Fintan]

trying to install deb gives me too many unmet depenencies.

[Snowhog]

I think the issue is the fact that in order to pull in the required dependencies for wifi, you have to have an active network connection -- ethernet. I think that you are going to have to find and connect the laptop to a working ethernet first. A classic 'chicken or egg' senario.

[Fintan]

Yeah I agree.

[Fintan]

Still, I can't fathom why it works from the live usb and not from the install!!

[wizard10000]

firmware-b43-lpphy-installer_015-9_all.deb

or


firmware-b43-installer_015-9_all.deb
?

The first one. LP-PHY is the low power version of the BCM4312 and that's what lspci detected; I had one in my netbook until I replaced it with an Intel card.

-- sorry, snowhog

Unless you want to load a buncha dependencies on a thumb drive you'll need an internet connection to do this; the firmware installer downloads the driver from Broadcom, extracts the firmware only and installs it.

Also, with this particular chipset I've had better luck with the STA driver than with b43.

edit: Another option would be to replace that BCM4312 with an Intel card. I'm really not a fan of Broadcom wireless cards for Linux, preferring Atheros or Intel. Hardware would cost about $20, you should be able to swap out the wireless card without gutting the laptop and would resolve this issue permanently.

Doesn't apply here but for our studio audience, please to be noting that you can't swap out the wireless card with HP or Lenovo laptops though - both companies whitelist their WLAN cards in BIOS and will refuse to boot if you swap out the wireless card without installing a hacked BIOS (or hacking it yourself). I had to find a hacked BIOS for my netbook to get the Intel card to run. On an eMachine this shouldn't be an issue.

cheers -
