    Edimax EW-7318USg

    I'm trying to get an Edimax EW-7318USg working on my system. I searched online to make sure it worked well with Linux before purchasing it (says it should work "out of the box" here), and now I'm thoroughly frustrated with it. When I plug it in, nothing happens, NetworkManager does nothing with it. So off to find the source, try to compile and install it, and I can't get it to work.

    First, I tried following these instructions: http://ubuntuforums.org/showthread.php?t=836577
    But then I couldn't find the driver source (as linked to in the thread), so looked around for different instructions.

    Next, I tried following these instructions: https://help.ubuntu.com/community/Wi...rt73_driver%29
    I downloaded the "RT2501USB(RT73:RT2571W/RT2573/RT2671" driver (here) and got down to the spot of running "sudo modprobe rt73", at which point my computer froze. Now if the Edimax is plugged into the USB port, my computer will either not boot or instantly freeze. (UPDATE: Decided to do a clean reinstall of Ubuntu.)

    Help?

    Re: Edimax EW-7318USg

    Couple of crazy ideas that might make a difference:

    The link you listed lists Ubuntu Intrepid and WEP specifically. I don't know why WPA might not work, or if you are using an older version of Ubuntu, but it might be something to think about if you get more desperate later

    Second, having the computer hang like that while doing a modprobe makes me think either hardware problem, or crappy drivers. If you have the option, try connecting to a different USB port.

    Sounds like snake oil, but it's all I can come up with off the top of my head. If I think of anything later I'll call or post

    I'm having similar difficulty with the same adapter. I've installed the adapter on my Win XP Pro machine with no problems, so the adapter can be found. It just isn't found by my Toshiba 1415-S173 laptop running Jaunty Jackalope 9.04

    Re: Edimax EW-7318USg

    After a clean reinstall of Ubuntu, I gave it another shot. This time I tried using the driver source code included on the CD out of the box the adapter came in. For reference, this is the filename of the driver it shipped with: 2008_0506_RT73_Linux_STA_Drv1.1.0.1.tar.bz2

    So I tried to configure it for making, but it needed the kernel source. So I did:
    Code:
    sudo apt-get install linux-headers-`uname -r`
    sudo apt-get source linux-image-`uname -r`
    sudo mkdir /usr/src/linux-2.6.28
    sudo cp -r linux-2.6.28/* /usr/src/linux-2.6.28/
    That seemed to work, even though "uname -r" yields for me "2.6.28-13-generic". I don't know if there's a difference between linux-2.6.28 and 2.6.28-13-generic, even though the apt-get command I ran asked for the more specific source.

    The make config didn't error out this time, but when I attempted to compile it wasn't happy:
    Code:
    queso@quark:~/dl/drivers/2008_0506_RT73_Linux_STA_Drv1.1.0.1/Module$ make config

    Re: Edimax EW-7318USg

    In accordance with this thread, I'm posting additional info about my system in case it helps:

    1 ) Machine Brand and Model (PC/Laptop):

    Self-built desktop, Intel Core2 Quad Q8300 @ 2.50GHz, ASUS P5N7A-VM motherboard

    2 ) Wireless Brand, Model and Wireless Chipset:

    lsusb:
    Code:
    Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 004 Device 002: ID 046d:c526 Logitech, Inc. 
    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 003: ID 04fe:0006 PFU, Ltd 
    Bus 003 Device 002: ID 04fe:0008 PFU, Ltd 
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 001 Device 002: ID 7392:7318  
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    I think "Bus 001 Device 002: ID 7392:7318" is the wireless usb, since when I take it out it changes to Linux Foundation root hub.

    3 ) check interface:

    iwconfig:
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    virbr0    no wireless extensions.
    
    pan0      no wireless extensions.
    4 ) Check for modules:

    lsmod:
    Code:

    Any ideas?
    Hi caseyb,
    I also bought today this cheap edimax and wondering why the support in 9.04 is not present. I hate wifi support on linux, this is one of the biggest weakneses of linux.

    Try to apply attached patch i created by copying it to /2008_0506_RT73_Linux_STA_Drv1.1.0.1/Module
    And run:
    Code:
    patch -p1 -i ubuntu_904_rt73.patch.txt
    make all
    Now the driver should compile and you should be able to continue in instructions provided in README file from original driver.

    Re: Edimax EW-7318USg

    As an Edimax EW-7318USG user, I thought I'd include my latest experience with Jaunty.

    NB: See EDITs below for further updates on progress...

    Remember, there appears to be a new version of this device - check lsusb to see which you have:

    Code:
    lsusb
    Bus 001 Device 002: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter
    The default driver appears to be rt73usb, which works with Network Manager. However, it intermittently misbehaves and refuses to connect, and particularly refuses to accept a correct WPA password.

    My thoughts (perhaps incorrect)...

    I have found rt2500usb driver interfering. Hence, I blacklisted it:
    Code:
    sudo nano /etc/modprobe.d/blacklist-rt2500usb.conf
    Add the line
    Code:
    blacklist rt2500usb
    Then Ctrl+X to save.

    This appears to ensure it always works, but it sometimes requires unplugging and replugging back in. Additionally, it frequently drops a signal, and has to reconnect.

    To resolve this, I tried the latest rt73 firmware:
    Code:
    sudo apt-get install rt73-common rt73-source
    sudo update-rt73-firmware
    A reboot later, and I have had a stable connection for about an hour now...

    Will report back later if it is as steady as my other wifi connections.

    EDIT: Another thread worth trying (did not work for me - yet):
    http://ubuntuforums.org/showthread.php?t=1215251

    EDIT2: Disconnects again overnight with Network Manager, and fails to reconnect with a prompt for password. Still trying...

    EDIT 3: Try this: http://ubuntuforums.org/showthread.php?t=1211513
    No need to blacklist anything (i.e. remove the blacklist-rt2500usb.conf file created earlier. Appears to work fairly well, with infrequent brief disconnections on Wicd 1.6.2 with default driver (rt73usb) using wext driver.

    EDIT 4: I suspect I have a hardware issue, since the device works for others.
