    Wireless problems with HomeHub 3

    Hey folks,

    I am having some big issues using wireless internet through my homehub 3.

    The homehub works fine on my desktop (and equally fine if i plug my kubuntu netbook to it with a network cable) but for some reason it misbehaves when i connect wirelessly...

    The netbook works fine in other wireless networks and, equally, other devices (smartphones and windows laptops) work fine wirelessly with my homehub. The netbook goes through the motions and connects to the homehub ok but when I try to load a webpage it times out at 'looking up google.com...' or whatever. I suspected DNS issues but when i tried to change it to googledns it still wouldnt work. Could the connection to the homehub be overrulling the dns server entries in resolv.conf?

    any help gratefuly recieved!

    Re: Wireless problems with HomeHub 3

    What is in resolv.conf, and how it is used, is different between versions of Ubuntu. What is in there?
    Code:
    cat /etc/resolv.conf
    lsb_release -d
    Do you have any settings in Wicd related to DNS? Can you ping by number?
    Code:
    ping -c3 192.168.1.1 <--or whatever your Homehub address is
    ping -c3 173.194.73.99
    What kind of (Intel) wireless card is in your netbook?
    Code:
    lspci -nn | grep 0280
    Thanks.

    Hey there,

    Thank you very much for replying. Here is the additional info:

    02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192E/RTL8192SE Wireless LAN Controller [10ec:8192] (rev 01)
    I am aware of lots of issues with the driver for this card but believe that it has been resolved from 12.04 onwards? (I had previously found instructions for installing the manufacturers one on the internet). Either way I do not think this is the same issue as I have no problems connecting to public wifi nor do I have problems connecting to my girlfriends (protected) wifi.

    I removed Wicd and went back to the default network manager after I found it hadnt helped. Can happily reinstall and check for DNS settings if needs be?

    Thanks again for taking an interest.

    Re: Wireless problems with HomeHub 3

    I'm not sure you're actually connected! Let's see:
    Code:
    iwconfig
    dmesg | grep wlan
    route -n

    Are there any manually added settings in there? Normally, none are needed.

    No, none. I have deleted and recreated the connection loads of times.

    ooo - that looks promising? IPv6 routers? should I change settings to IPv4 only? (im sure I have tried that before though?)

    I should perhaps just let you know that I am plugging and unpluging a network cable each time to let me get online to respond (just in case its affecting any of the above?). Each time I make sure that i show as connected to the wireless netword but disconnected from the wired to generate the output then go online to paste it here...

    It's trivial. It just means the system doesn't see any IPv6 capable routers out there so it isn't going to bother going through the motions of asking for and waiting for an IPv6 address. You can speed things up by, oh maybe 1/100th of a second if you set IPv6 to ignore in Network Manager.

    Please detach the ethernet cable and so we have a clean slate, reboot. Then run:
    Code:
    dmesg | grep -e 819 -e wlan
    sudo cat /var/log/syslog | grep etwork | tail -n20
    cat /etc/resolvconf/resolv.conf.d/original
    Post them here. I love a mystery!
