    Angry Can't connect to internet (wired or wireless) on 10.10 Maverick

    Hello!

    I've had Ubuntu installed on my laptop for around 7 months, starting with 9.10, then upgrading to 10.04 and 10.10 when they were released. I've never had issues connecting to the internet before but now I seem to have lost it.

    I'm dual-booting Windows Vista and Ubuntu 10.10 on an ASUS G71Gx. I was able to connect to my wifi (no security) and access the internet just two days ago but I lost it yesterday. At first I thought it was just my ISP, but now my desktop running Windows XP (ethernet) and my desktop running Ubuntu 10.04 (using a USB wifi adapter) have full internet connections. My laptop can connect to the router and I can access the config page (192.168.1.1), but I can't reach any other web sites or even other machines connected to my router. This happens with both wireless and wired.

    If anyone can help I would gladly appreciate it! I'm willing to run any commands and post the output or give any additional information. I really would like this fixed soon.

    Thanks in advance!

    HI,
    I have got a similar issue here.
    I have noticed that I can connect to the access point, but when I start Chrome or Firefox, Pidgin, they couldnt connect to the Internet. However, the updates are working perfectly.
    So I decided to start Firefox as sudo and here we are, the problem is sorted.
    The only thing is, how do I change the rights of my account, knowing that it has never been restricted? What should I do?
    It is not really handy to have to launch all the application as sudo

    Regards

    Guillaume

    Try the OpenDNS nameservers. Click network icon and then edit the connections select DNS and give the ip's to OpenDNS

    I don't see how it will fix his problem, he has no issue running Internet via Windows, it is obvious that the problem comes from Ubuntu

    Hi baldurmen! Sorry you're having trouble accessing the Internet wirelessly.

    To try and figure out what's going on, I'm going to have you collect some information. To do so, you'll need to go to Applications > Accessories > Terminal. In the black box that appears, type the following and press Enter:
    Code:
    lspci -v
    Then, copy and paste that in a post here. That lists your hardware and the drivers installed and activated for them.

    Then, type this and press Enter:
    Code:
    ifconfig -a
    and copy/paste that too. That's your network configuration.

    Next, type this and press Enter:
    Code:
    sudo iwconfig
    You'll need to enter your password when asked and press Enter. Then copy/paste that too. That shows us your wireless setup.

    Just one more thing. Type this and press Enter:
    Code:
    uname -r
    and copy/paste that (this one's only one line). That tells us what version of the Linux kernel you're running. One particular version is giving people trouble.

    With all that in hand, we should be able to figure out what's going on. Thanks!

    (And if anyone else in this thread is still around, feel free to reply with all that also.)

    Re: Can't connect to internet (wired or wireless) on 10.10 Maverick

    Is there any way you can plug that computer into a wired Ethernet connection? There is an updated driver for your wireless card you could download that might help.

    If not, I can tell you how to download it on another computer and transfer it with a flash drive, but it will be bit more complicated.
