    Ubuntu Wireless Adapter Installation

    Hi All,

    I am relatively new to Linux and was wondering if anyone could point me in the right direction with a problem I am having.

    I have installed Ubuntu 11.10 on a desktop PC and would like to get it connected to the wireless network. We have bought a Edimax EW-7722In PCI card which I have installed.

    The driver is available from the Edimax website and I have compiled it (to the best of my knowledge) using make, make install.

    Looking at the back of the PC, I can see the LED on the card flashing and when I disable the wireless capability in Linux this stops so the OS is clearly communicating on some level with the device.

    If anyone is able to offer me any advice with this problem I would be very grateful. I have attached the WirelessSetup file generated by the diagnostic file provided on this site. Hopefully this will provide some useful information...

    Many thanks in advance

    Did this because it is easier to read than going back and forth in Geany.

    wlan0 (which is your wireless interface) is showing up in iwconfig and ifconfig. I don't run Ubuntu 11.10 so someone else will have to tell you how to connect with Ubuntu 11.10 default network manager.

    wireless adapter

    This is a long shot so forgive me if I,am off base. In synaptic I typed in edim and ap-utils came up. with access point support for Edimax WLAN. Give it a read and see what you think. If your like me I would download it and often get lucky. You can always remove it if no help.

    Thanks for the suggestion wimstock.

    I have had a look at this without success i'm afraid. TBH I think that program is for remote administration of access points using the SNMP protocol whereas what I am actually after is a way to install and configure a driver for a PCI card.

    At the moment, I am unable to say for certain that the card is working. It is entirely possible that the card is faulty. I am going to take it into work with me tomorrow and install it in a Windows PC (something I am a bit more comfortable with!). At least then I will be able to rule faulty hardware out as a cause of the problem.

    Thanks again

    This page may be of help. Scroll down to the entry for the E-W7722IN.

    https://help.ubuntu.com/community/Ha...orkCardsEdimax

    Supposedly you have to compile the Ralink drivers for RT3062 and blacklist the rt2800 and rt2x00 modules.
    Please note that was tested on Ubuntu 10.10
    Not sure about newer versions.
