    Default Not your normal networking connection isssue

    I am trying to connect to the internet via wireless using the Live USB install. I try WICD network manager but I'm having the same problem reported all over the internet where it won't assign an IP. So I get the bright idea that I will just connect manually via IWConfig commands. This works, I get assigned an IP and even when I look in WICD it shows me as connected. But when I attempt to actually look at anything on the internet it can't find it. FF times out with an address not found error.

    Any help?

    Since you havent mentioned the commands you used to configure your card what follows will be a bunch of random guesses as to what your problem might be.

    Do you have the correct default gateway set?
    Do you have a correct DNS settings configured?

    Have you attempted a packet capture to see what is happening on the network?

    Here are the exact commands I type

    ifconfig wlan0 up
    iwconfig wlan0 essid (name)
    iwconfig wlan0 key (wep key)
    iwconfig wlan0 ap (BSSID)
    dhcpcd wlan0

    According to route the gateway is correct.

    What about a DNS server, and what does a packet capture tell you?

    Sorry it was late last night. Thanks for your help.

    The DNS sever as per resolve.conf are correct.

    Packet capture throws the error "Host unreachable". What's interesting is that it shows the source and the destination IP to be the same one, namely the one on the local network. What could be causing that. The gateway IP is set correctly.

    Can you resolve host names?

    How are you doing that packet capture? Can you ping the gateway and get a response? What about beyond the gateway?
