Broadcom BCM4312

[chriswebs23]

Have just installed Ubuntu 12.10 on my old HP Compaq 6720s...

Hoping it would run quicker and simpler than Vista.

At the moment i am regretting the move to ubuntu because i cant connect to my home or work wireless internet connection.

Its just not as simple as vista. I have no experience with ubuntu i just want my work laptop to connect to the internet!

Any help would be great... considering switching back to vista...

[chili555]

Once you solve the wireless piece, I think Ubuntu will indeed be simpler and faster than Vista. Let's see what kind of wireless card you have. Is it a PCI card built-in? Please open a terminal and run this command and post the result:

lspci -nn | grep 0280

The pipe symbol | is on the right side of my US keyboard on the same key with \.

If your wireless device is USB, please post:

lsusb

Thanks.

chris@chris-HP-Compaq-6720s:~$ lspci -nn grep 0280
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>] 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

Welcome to Ubuntu!

I know this sounds silly, but how comfortable are you with the user interface?
Have you discovered where the network manager icon is? On the top right of the screen? Have you clicked and right-clicked on it?

Please god, don't go back to vista.

[westie457]

Hi and welcome to the forum.

Plug an ethernet cable in, it is necessary at this stage.

Open a terminal, type in and run these two commands please.

sudo apt-get install b43fwcutter

sudo apt-get install firmware-b43-lpphy-installer

When this has finished wait a few seconds and click the Network Manager icon at the top of the screen. It looks like piece of pie.

Any available networks will appear there, choose yours and enter details as necessary. You should be up and running.

If nothing in network manager run

sudo modprobe b43

and try Network Manager again.

If there is no joy after trying all the above post the output of

lsmod

Thank you.

[chriswebs23]

not very used to the interface at all!! i loved XP, and have windows 7 on my home Desktop... I am trying to give this old junk laptop a new life, have always been windows so this is all new to me...

I have a wired connection no problem... have done the whole 192.168.1.1 stuff to get details about my home network and entered those into the Network Connection -> Wireless panel... and/ it just will not work, how do i know if my internal wireless card is recognized/installed...

All i want this laptop for is using and editing my Excel work doc's and web use at work to sync with my android and Pc.

Oh and to keep me entertained while flying for 12 hours...

chris@chris-HP-Compaq-6720s:~$ lspci -nn grep 0280

You forgot the pipe symbol I referred to above; however, we have what we need:

Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315]

Please try:

sudo apt-get install linux-headers-generic bcmwl-kernel-source
sudo modprobe wl

Is it working now?

[chriswebs23]

thanks for helping guys!
