    Wireless Adapter Not Detected ... but it used to be!

    I will bold the areas where there is the most important information! Some of this post may be irrelevant, so I won't bore you with the details, unless you wish to read all of it.

    This machine is a Compaq Mini 110c-1105DX (netbook), running Ubuntu Maverick 10.10. I installed Ubuntu on this machine for a friend whose trial license ended for Windows 7 Starter Edition (ew).

    When I installed Ubuntu approximately 19 days ago from the date of this post, the Wireless Drivers were not detected, and I had to jump through quite a few hoops to get them working. Some b43 packages were missing. I had to compile b43-fwcutter-011 from source. This was the eventual solution.

    Two days ago, my friend came to me telling me that Wireless no longer worked. Specifically, Ubuntu no longer detects the on-board wireless adapter. The networking icon in the System Tray does not list a "Wireless Network" subtitle, and only a "Wired Network", showing eth0.

    There is evidence the machine could at one point connect to wireless networks. Under System -> Preferences -> Network Connections on the Wireless tab, is a list of wireless networks connected to and when they were last used. My network displays that it was last used 19 days ago. Its home network was last connected 5 days ago.

    Miscellaneous Details

    • I have already tried this.
    • Ubuntu does not complain about any drivers or errors whatsoever.
    • Yes, the machine's hardware switch indicates that the internal card is indeed on, however, I cannot turn it off. The user manual indicates the switch will be blue, and it is.
    • Some commands I ran that may be useful to the reader:

    lshw -C network (this command was run while connected through Ethernet)
    Code:
    thault@baby:~$ lshw -C network

    Upon request, I will post more details of commands! I am about willing to try everything, even OS reinstall.

    I appreciate the quick reply!

    Synaptic spit this out at me when I marked for reinstallation, however the sticky said to mark for installation.

    Code:
    E: firmware-b43-lpphy-installer: subprocess installed post-installation script returned error exit status 255
    I will experiment more between system reboots.
