Everything went fine with ubuntu netbok (Ubuntu 11.04 – the Natty Narwhal – released in April 2011 and supported until October 2012. ) remix but wireless failed, it was frustrating but i solved it with good people from linuxquestions.org

i installed ubuntu netbook remix , when connected with cabled it was fine but not in wireless mode

solution

first try to locate your driver ( device details)

as per LQ support

It seems the wireless chip in this machine is a RTL8188CE.

If that is the case, the driver is not yet included in Ubuntu, but there is one available. I found a PPA that packages it.

Code:

sudo add-apt-repository ppa:lexical/hwe-wireless
sudo apt-get update
sudo apt-get install rtl8192ce-dkms

after this go to network applet and check wireless enable

then connect to wireless network ( name your network here)

i did the same and now connected to WLAN and posting this from Wifi

  1. Dude… thank you so much for this.. i got a dell mini and the wifi died after the updates… the jokers at dell were of absolutely no help…. instead they asked me to go buy windows7… Ubuntu rocks.. this is the first time i have used it and i love it…

    Thanks again… cheers…

  2. Thnx for the gr8 help.. few days ago I had the same prob, Installed the broadcom dirver and rtl’s driver.. the wifi started working again.. now yesterday it crashed again.. I dont know why..
    Finally I had to remove the rtl and broadcom package from the Synaptic package manager
    Applied the above 3 steps.. rebooted my dell.. and wifi started working and now m on wifi 😀

  3. Hi! I had the same problem with my Dell Inspiron 1018 and I have fixed it using this thread and others, however even if mu WiFi card is working now it is extremely slow and laggy, for example – I have 2 notebooks, I have checked the connectivity from the other one (Acer aspire 5535) and the connection is wonderful.

    Please tell me how can I resolve this frustrating problem.

    Looking forward to hear from you all!

  4. H i’ve tried the three steps
    The card is the same
    But in the first the system says “cant decode byte 0xc3 in position 33: ordinal not in range(128)”
    Then, the second says that it’s not possible to resolve “ppa.launchpad.net”
    After, the third “is not possible to localize the package rtl8192ce-dkms”

    so, any idea?

    Thanks a lot

  5. Ubuntu wins hands down when it comes to robustness and openness. The only issue I face is with respect to the application I use in particular, which are designed for PC. I can’t love without Ubuntu though, and use it all the time on my other laptop. Faced some issue with Wifi connectivity during the past week and this sorted my problems. Thnx a tonnne for this great article.
