UPDATE: Fix for BCM4313 (4727) when running Ubuntu 10.04 LTS on same hp dm1 laptop
OK, so I started fiddling with partitions on the laptop (which has a whole thread all to itself
) and ended up installing 10.04 on a small partition on the same laptop. Wireless, of course, did not work again.
Using sudo lshw -C Network showed the network as UNCLAIMED which according to the 10.04 troubleshooting guide at https://help.ubuntu.com/10.04/intern...-wireless.html indicates there was no driver associated. The STA drivers did not turn up as an option to activate in the system preferences at all. Rather than using wired to download the bcmwl-kernel-source I decided to follow this guide
https://help.ubuntu.com/community/Wi...Driver/bcm43xx
namely the option STA - No Internet Access. I followed the steps closely, with a few variations:
1) stick in the install USB and navigate to the packages listed below, then double-clicking to install:
../pool/main/p/patch (the guide had this as second but patch was a dependency to dkms which would not install without patch being installed first)
../pool/main/d/dkms
../pool/main/f/fakeroot
../pool/restricted/b/bcmwl
2) restart (the second step in the guide, to navigate to system administration -> drivers -> STA drivers did not work, the STA driver still did not show; it appeared only after I connected to the internet and installed a bunch of updates)
3) Hit the hardware switch to make sure it is not blocking the connection
4) The next day the wireless network was showing as UNMANAGED and did not work again; I googled around (on a different device, obviously
) and came up with the following:
Code:
gksudo gedit /var/lib/NetworkManager/NetworkManager.state
and change NetworkingEnabled=false to NetworkingEnabled=true and also
Code:
gksudo gedit /etc/NetworkManager/nm-system-settings.conf
and change managed=false to managed=true
I took this from post #4 in this thread http://ubuntuforums.org/showthread.php?p=9402242
Wireless on the 10.04 partition has been working since then but it is noticeably slower than the wireless on the 11.10 partition. Oh, and it disappeared once by itself after suspend; the setting in one of the files listed in 4) above had reverted to false so had to change it back to true.
All in all having lots of fun with the wireless Broadcom driver and seriously thinking about buying a USB wireless card just in case the internet disappears completely at some point. Using a wired connection or a mobile device to get to the internet to troubleshoot and search for answers may not always be an option
Still, troubleshooting the wireless connection has helped me learn a lot about the system, where things are and how to use the terminal to do useful stuff. Very happy with Ubuntu and looking forward to 12.04
