    Wireless problem in Ubuntu, moving from Vista

    Ok, so I have been a windows user up till now, but ive read some impressive and convincing articles about Linux. Because of this, I made a live CD for Ubuntu. (I am a COMPLETE newbie in Linux, and almost helpless when it comes to settings for internet and wireless, so no weird names or acronyms please ).

    I came to realise there was no internet available, and I googled it. Some pages suggested that wireless would work much better if I had Linux installed. So I decided to do this. But, after spending time and space to install it in addition to vista, I sat there with the same problem... Internet wouldn't show.

    Now, I highly susppect this has all to do with my computer, which seems to be vistas favourite student (-___-). There is only one way to activate my wireless card and that is via the "Wireless Status Option", which can only be opened with Fn+F1 (at least from what I could google out in 2 hours). There is supposed to be another way, you can log into vista, activate internet, turn off the (shut down network card upon restart) thing, and log back to Ubuntu. But seriously, I don't want vista to be there at all, nor do I want to spend 5-10 minutes extra because of turning on internet... When going into Linux, clicking the network Icon, I can see that the three first wireless options are gray, unselectable (They read Wired Network; disconnected; Wireless Network, respectively). Does this mean that the Wireless card is off? Any way around this?

    Judging by my Console Management, my network cards are
    1. Atheros AR5007EG Wireless Network Adapter
    2. Realtek RTL 8101E Family PCI-E Fast Ethernet NIC (NDIS 6.0)
    I guess im supposed to look at the first one. I dont know if its built in or PCI or USB or whatever, but I bought it complete, its a laptop, and I havent added anything to it.
    I typed uname -r and got this as a result: 2.6.28-11-generic

    I tried to post the results I got from the terminal, but I failed. (Somehow I couldnt post the lspci, lsmod and dmesg files because apparently they contained URLs :S )
    I tried to put them up as *.txt attachments, but dmesg was too big, so I had to compress it :/

    But all three files are in the attachment, each of them named after the command I used to get them.

    I hope this was everything needed, tell me if you need to know more.
    Thanks in advance

    Hi and welcome.

    Can you post the output of
    cat /sys/class/rfkill/rfkill*/state
    It will just return a number. 0=off 1=on

    Also, try
    sudo ifconfig wlan0 down
    sudo modprobe -r ath5k
    sudo modprobe acer_wmi
    sudo modprobe ath5
    sudo ifconfig wlan0 up
    and check your wireless again.

    For anyone else looking at this thread, the pertinent bits of the output

    Did you say you could get a wired connection?

    If you can, do so and try installing the following
    sudo apt-get install linux-backports-modules-jaunty
    Then restart.

    Problem number 2: UPDATING

    Thank you very much, reed9

    the cat /sys/class/rfkill/rfkill*/state didnt seem to work before I tried the series of commands you listed, but after that, it worked !
    Im on linux right now, actually ; D

    But now, I met another problem... A window popped up with a lot of updates, and when I press "update", it tells me that I dont have enough disc space... (400 something mb). And I just got it ;S

    I have 2 harddisks, one with some 35-40 GB free and another with more than 250 GB free...
    I might have been stupid when installing Linux to my drive. I couldnt choose which harddisk to put it in, but I think I put it in the 35-40 GB one ( C: ).
    Then, I as good as skipped the step with the space slider thing... should I not have done this? I think the slider way waay up, taking all of the space(?).
    I hope its not what I think, that I spent the entire thing on the linux system, and nothing for the data... Explain please
    EDIT: I can't install custom programs either :O !!
    EDIT 2: My FileSystem harddisk (this must be where linux is installed, partition or something, ive never seen it before) has 0 bytes of free space available... out of 20 + GB

    Later, I will want to get rid of vista and put Linux as the main OS on the C drive... To do this, should I reformat and reinstall Linux?

    It sounds like you didn't allocate enough space to the root directory.

    Can you post the output of
    sudo fdisk -l
    df -h
    EDIT: I can't install custom programs either :O !!
    What programs? Are they windows software?

    Later, I will want to get rid of vista and put Linux as the main OS on the C drive... To do this, should I reformat and reinstall Linux?
    That would probably be the best way to go.

    Can you also post which thing solved the wireless problem, for anyone else with a similar problem looking for a solution?

  7. #6

    Problem upon problem? :S

    To solve it, I wrote this code into the terminal:
    sudo ifconfig wlan0 down
    sudo modprobe -r ath5K
    sudo modprobe acer_wmi
    sudo modprobe ath5
    sudo ifconfig wlan0 up
    After I had done that, the wireless card was on, and the light on my computer indicating wireless activation was on.

    The softwares I tried downloading all supported Linux. The problem was that there wasnt enough space to download... The softwares were Blender 3D Linux version, Alchemy (cross-platform) and wxMaxima, Linux version. None worked.

    I tried opening other built-in programs...
    Tomboy notes didnt respond at all.
    OpenOffice programs responded with "The application cannot be started. An internal error occured".
    Gimp couldnt open either, because it had to create a folder ".gimp-2.6", and there was no space for it.

    Other problems I noticed when starting Ubuntu today was that the sound, network and Date + Time buttons were all gone from the top right corner, as well as the workspace switch buttons in the bottom right. So I couldnt connect to the internet, but the hotkey for sound worked and I dont know about the workspace switching, because I forgot the shortcut.

    Whats happening? :S

    This is what's happening. Your root partition, which contains all the system files and the cache of downloaded packages, is only 2.3 GB. It's simply not big enough.

    Then, I as good as skipped the step with the space slider thing... should I not have done this? I think the slider way waay up, taking all of the space(?).
    This is where the mistake occurred, I'd wager, as you suspected.

    You may be able to resize the partition. I like to use Parted Magic for partitioning. You can also boot the Ubuntu live CD up, I believe it includes gparted.

    All in all, it may be easier to reinstall, though.
