    Default DNS issues.

    Hi All,

    I seem to be having name resolution problems on BT4.

    I can connect via Ethernet and get internet, i can connect to other access points and have internet but i just cant seem to connect to my access point anymore.

    Its odd as i have tried everything. Manually connecting to the access point using wpa_supplicant, stopped and started networking multiple times, rebooted, manually set dns server and IP address but no success.

    I am fairly familiar with linux, I just cant seem to get this damn thing to work.

    It associates but It cant resolve host names.

    Help would be much appreciated

    Cheers,
    Kyle.

    I think you're going to need to provide more detail.

    After confirming that your network setup is appropriate by successfully connecting with some other system, explain how your network is setup and the exact steps you used to configure networking on BackTrack plus the output of the relevant configuration commands and files, as well as outputs from the appropriate diagnostic tools. Since you mentioned that you were familiar with Linux I'll assume you know which commands, files and tools Im referring to.
    Capitalisation is important. It's the difference between "Helping your brother Jack off a horse" and "Helping your brother jack off a horse".

    The Forum Rules, Forum FAQ and the BackTrack Wiki... learn them, love them, live them.

    OK when i say 'familiar' I mean in my own ranking system if you will.. ha ha.

    My network settings are fine as i have 3 PC's already connected on the network and 2 of them use wireless. The annoying part is backtrack used to connect to the wifi and now it doesn't.

    If you could tell me what to check for and what to run it will both teach more how to as well as give you more info on the problem.

    Cheers.
