Whatever I typed it must have reset everything because now wireless isn't showing up in the Network Settings box. Also I've noticed while it boots it throws up several errors about being unable to allocate pci or something.


please PLEASE HELP!! :(

HI and are you sure you linked the right thread because it directs for the reconfigure of the xorg that should not effect your network.

hi, thanks so much for your reply.

Yeah, everything was all working great until lastnight i tried to change video driver, earlier today i found a reference to that command and tried it out (sudo dpkg-reconfigure -phigh xserver-xorg), which made the video come back but now wireless is not even acknowledged in network manager.

also i did i tried some command (lshw -C network) in the terminal which shows the wireless and ethernet adapter, ethernet has been assigned a name but wireless has not.

help!!

edit: also another thing which it did not do prior to that command, when booting up, it moans about being unable to assign pci or something, it lists it about 6-8 times, but i cant read it properly as its too quick.

You can view the boot process messages with this:

gedit /var/log/dmesg

You can also print out only certain lines of the above in terminal using a search. Just replace the word after 'grep' to change the search term (e.g. error, pci, wireless, etc)


cat /var/log/dmesg | grep error

Did you try looking through the entire file to see if there was anything that stood out error-wise? Sometimes there will be something that even a non-techie can understand.

You could also run this to see what pci stuff is known by the computer:

lspci

Unfortunately I'm better at finding the code than reading it ;-)

I can see wireless is in the list, but it just doesnt show up in network manager like it used to. I'm currently using ethernet to connect but i am not always at home so will need the wireless.

Is it easier if i just re-install ubuntu?

Some restored their card with this command:

sudo apt-get install linux-backports-modules-hardy-generic

I found several threads for your wireless card regarding lost wireless after upgrading. Search the ubuntu forums for " Wireless 3945ABG" if the above doesn't help.

i typed it in and got this.

edit:

ok after typing

lshw -C network

i get this:

To download them, you might have to enable the synaptic, settings, repositories, updates, unsupported updates (ticked).

Seems like there would be a more-supported solution, but you might want to give it a try.

same error, E: Couldn't find package linux-backports-modules-hardy-generic

i'm getting fed up with it now, honestly why is it so difficult to make it work! Who come up with this idea and who agreed!!
