    Default CANNOT CONNECT TO INTERNET open wireless router but can connect to WEP

    I'm having a bit of a dilemma here with BT4. I can connect to my router that is secured with WEP using

    Code:
    sudo ifconfig <interface> down
    sudo dhclient -r <interface>
    sudo ifconfig <interface> up
    sudo iwconfig <interface> essid "ESSID"
    sudo iwconfig <interface> key KEY
    sudo iwconfig <interface> mode Managed
    sudo dhclient <interface>
    but I cannot connect to my other router that is UNSECURED / OPEN (no password) Using code above as well minus key part.

    I've tried using
    # iwconfig wlan0 channel 12
    # iwconfig wlan0 ap [MAC_OF_THE_ROUTER]

    as well, and still no luck.

    This is what I get
    Code:

    For info, please visit http://www.isc.org/sw/dhcp

    DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 2
    No DHCPOFFERS received.
    No working leases in persistent database - sleeping.

    When I use WICD Manager as well, its stuck at "Obtaining IP address..." and it never connects.

    Tried everything on google and BT forums (past and present)

    Thanks in advanced

    Default Re: CANNOT CONNECT TO INTERNET open wireless router but can connect to WEP

    I too get this problem on a daily basis, I have recently been wondering if it could be because I am too close to the AP. My main problem is on my main AP - I cant connect despite having 45% signal. Are we the only ones this is happening to?

    Have you tried connecting via Windoze? I can usually connect straight away with it, so I am assuming (But dont know) that is it a BT4/Linux thing?

    Check the DHCP settings on your router.

    Have you ran
    Code:
    networking start
    Your iwconfigs can be run together
    Code:
    iwconfig interface mode managed essid "whatever" ap **:**:**:**:**:**  key qwerty1234
    I've always run dhclient after iwconfig and putting the card back up.
    Code:
    ifconfig interface down
    iwconfig interface mode, etc.
    ifconfig interface up
    dhclient options interface
    Btw, Neither of your routers are secure.

    On Windows I can connect to it right away with no problems so I'm not assuming a problem with the router.
