    Wireless issue in 12.04 - Problem with DNS Settings?

    Hello

    I am a relative newcomer to Ubuntu (and the forums). I have had Ubuntu on my laptop for a few months now. I upgraded to 12.04 a couple of weeks ago and since then, I cannot use the wireless. It somehow connects and opens to my homepage, but then there is an error message which says the 'DNS lookup failed'. I only have this problem with my home wireless and nowhere else...yet.

    I have looked at some other help topics about wireless issues and DNS settings, but as everything is so new to me, I don't understand it all

    Any help would be greatly appreciated and I hope I explained my problem.

    Re: Wireless issue in 12.04 - Problem with DNS Settings?

    Can you set IPv6 to ignore.

    Go to your network connections and click edit connections, go to wireless, select your ssid and click edit. In IPv4 settings add 8.8.8.8 and 8.8.4.4 in the DNS Servers field, move to IPv6 settings and select the method to be ignore.

    Hi, I have done as you said, but it hasn't worked.
    I have attached a screen shot, just in case it helps.

    Have you tried

    Code:
    Automatic (DHCP)
    instead of

    Code:
    Automatic (DHCP) addresses only

    Re: Wireless issue in 12.04 - Problem with DNS Settings?

    The original setting was as 'automatic DHCP' and the only way I could change the DNS settings to 8.8.8.8 and 8.8.4.4 was to change to automatic DCHP addresses only.

    There are also these options -
    Automatic (DHCP)
    Automatic (DHCP) Addresses only
    Manual
    Link-local
    Share to other computers
    Disable

    Is there anything I can do with those?
    Thanks!

    Re: Wireless issue in 12.04 - Problem with DNS Settings?

    ^^^ unfortunately that's getting into the territory of dnsmasq which I know nothing about (I'm still on 11.10 - which uses a conventional upstream DNS server model)

    you could at least try

    Code:
    sudo service dnsmasq status
    and then
    Code:
    nm-tool
    to check that it's running and picking up your chosen server(s), and maybe

    Code:
    grep -i dns /var/log/dmesg
    to see if there are any obvious error messages? (I see a lot of blocked multicast packets but I have no idea if that means anything).

    Good luck
