    Unhappy Unable to add Wireless Network Connection

    I have just entered the Linux world... so be kind I have an older Dell Latitude Laptop that I wiped of Win98 and loaded Ubuntu. Now I'm trying to get a LinkSys WPC-11 wireless PC card to work. It's not. It is showing up when I run a diagnostic command, but when I go to Preferences > Network Connections > Wireless > "Add" and enter all the information for the network the "Apply" button does not make itself even available to be clicked.
    What do I do to add a wireless connection?

    welcome to the forum

    well, depending on the WPC11 version, you need either
    the b43 driver--version 3--or the rtl8180 driver--version 4.
    These are included in the linux kernel.

    once the appropriate driver is loaded, you can do something
    like this to set up the card, substituting your own
    parameters, assuming WEP 64-bit encryption

    ifconfig wlan0 up
    iwconfig wlan0 essid 2236a
    iwconfig wlan0 channel 40
    iwconfig wlan0 mode managed
    iwconfig wlan0 key ..........
    iwconfig wlan0 key open
    dhclient wlan0

    How do I load a driver? Is this driver included in the Ubuntu bundle or is it found on the web? and how do I see that that the driver is loaded properly?

    I am having similar issues. After entering

    lspci -v | grep -i Network
    sudo lshw -C network

    This is what I have

    One light is solid, the other is blinking. Network manager recognizes it because wireless networks is accessible, but no networks show up, even when I know I am near them. I have no idea what to do and have tried almost everything I could find. Many reinstalls later, I'm stuck in the same position. Can anyone help?

    I had a lot of success with a wpc54g using ndiswrapper. Just download ndiswrapper, download the windows driver for the card and follow the instructions for ndiswrapper to create a wireless driver. More info here:
