    Wireless: Can see networks, but can't connect

    Alright, I've been struggling with my internet in Ubuntu for the last two days. I'm giving it one more go and if this doesn't work I'm scraping the whole Linux idea completely.

    I followed the guide and blacklisted the stock bcx (or whatever they are) drivers and installed Ndiswrapper (to my knowledge). I then installed the drivers for my wireless card. Everything seemed great. I was relieved to find that I finally could see my wireless connection. But! But! I can't connect. To anything. I can't connect when it is secure, unsecure, visible, invisible, WEP, WAP, WAP2, XYZE6! It does it's little 'trying to connect' thing, and nothing. I checked ndiswrapper -l, and it said the device and driver were both installed. I checked lspci and everything seems fine. I really have no idea what to do.

    I should note that I do not have a hard connection to the computer with Ubuntu on it at the moment. If you need me to get any information from the terminal I suggest you request it in bulk as I will have to run back and forth between computers to get it to you.

    My card is the D-Link DWA542. Someone suggested I use Madwifi, but it doesn't list this as one of their supported cards. Also I think if I can at least SEE the wireless networks around my house then there is some sort of connection going on between Ubuntu and the card.

    Any help? Thanks.

    Re: Wireless: Can see networks, but can't connect

    Can you post output of following commands:

    Code:
    lspci
    Code:
    iwconfig
    Code:
    dmesg | less
    Code:
    cat /etc/network/interfaces
    Code:
    cat /etc/modprobe.d/blacklist
    Code:
    iwscan
    And finally , are you using WPA/WEP or WPA2?
    You came empty handed, that is how you shall leave. Whatever you claim as yours today, belonged to someone else yesterday, will be someone else's tomorrow.

    i can see your wireless card is not configured at all and your chipset is bcm4318.

    This guide will work for you, try this http://ubuntuforums.org/showthread.p...05#post4604505

    I can connect to the unsecured networks, but not to the secured.

    That means your wireless card is working ok. you need to configure your WPA to access your access point. Have you tried network manager?

    Re: Wireless: Can see networks, but can't connect

    Okay, I think it's fairly important that I mention that I have given up on ndiswrapper at the suggestions of a couple users in IRC. I have since moved on to Madwifi with supposed supports my chipset. I also now have a hard connection to the internet so it will be much easier to provide feedback. I have tried to install Madwifi by following this guide: http://madwifi.org/wiki/UserDocs/Fir...roubleshooting and although I didn't seem to get any errors, it still doesn't seem to be picking up my card.

    Sorry I gave you wrong command before -

    Can you post output of the following:

    Code:
    sudo iwlist ath0 scan
    Code:
    sudo iwlist wlan0 scan

    Are you sure that you are able to see available networks through network manager?
