    EW-7728In, Ralink chipset problem with drivers

    Hi. Newbie Ubuntu attempt.



    The drivers for my PCI wireless network card wasn't downloaded automaticly, so I'm hoping for some assistance here.

    Ubuntu says: Ralink Unknown device 0601

    Card: Edimax, EW-7728In, nMax Wireless 802.11n PCI Card

    I downloaded the files at the bottom, but have no idea what to do with them. So I googled.

    I found a thread that said: "the 0601 is a Ralink RT2800 chipset, it's pretty new". Then it instructed another guy to download files here, but have no idea what to do with those either.

    I found some other threads like this one and this one, that just plain scares me.

    This might be necessary:
    2.6.24-19-generic


    So. Any ideas? Any ideas that a newbie can understand.

    Scare you? C'mon, compiling from source is just clean fun!

    First, be sure you have build-essential and linux-headers-generic installed. Synaptic is your friend. Then open a terminal and do, each command separately and in order:
    Code:
    lspci -v
    sudo lshw -C network
    Please verify you have a rt2860 device. If so, please proceed, if not, post back and tell us what you really have. Now do:
    Code:
    wget http://www.ralinktech.com.tw/data/drivers/2008_0522_RT2860_Linux_STA_v1.6.1.0.tar.bz2
    tar -xvzf 2008_0522_RT2860_Linux_STA_v1.6.1.0.tar.bz2
    cd 2008_0522_RT2860_Linux_STA_v1.6.1.0
    sudo su
    If your card will connect using WPA, we will have some adjustments to make:
    Code:
    gedit os/linux/config.mk
    In line 11, change HAS_WPA_SUPPLICANT=n to HAS_WPA_SUPPLICANT=y; in line 14, change HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n to HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y. Proofread, save and close. Now, do:
    Code:
    make
    cp RT2860STA.dat /etc/Wireless/RT2870STA/RT2870STA.dat
    make install
    modprobe rt2860sta
    Does your device wink, blink and spring to life? Can you connect?

    Hi

    My make doesn't work - but it might be some of my dependencies since this is an initial install.

    When I try the make I get:

    make
    make -C tools
    make[1]: Entering directory `/home/shaun/Desktop/2008_0522_RT2860_Linux_STA_v1.6.1.0/tools'
    gcc -g bin2h.c -o bin2h
    bin2h.c:28:19: error: stdio.h: No such file or directory
    bin2h.c:29:20: error: string.h: No such file or directory
    bin2h.c:30:20: error: stdlib.h: No such file or directory
    bin2h.c: In function ‘main’:
    bin2h.c:34: error: ‘FILE’ undeclared (first use in this function)
    bin2h.c:34: error: (Each undeclared identifier is reported only once
    bin2h.c:34: error: for each function it appears in.)
    bin2h.c:34: error: ‘infile’ undeclared (first use in this function)
    bin2h.c:34: error: ‘outfile’ undeclared (first use in this function)
    bin2h.c:42: warning: incompatible implicit declaration of built-in function ‘memset’

    Any ideas what I'm missing?

    Yes. You are missing build-essential and linux-headers-generic which you can install, given an ethernet connection, with Synaptic.

    Yes. Phew! It finally works.

    The first day I attempted this, Ubuntu continuously froze. Then I went away for some days. Today it worked after:
    - I had trouble downloading due to proxy problems
    - the bz2 wouldn't unzip, cause it wasn't gzip format. But it worked when I used File Browser to unarchive.
    - it wouldn't build cause I was missing some build-essential and stuff
    - Then no Wireless folder so I had some "make install" trouble
    - Finally roaming didn't work so I had to set it up manually

    But it was also kind of exciting. In a technological adventurous way.

    Thanks. I wouldn't be here without your help!

    I'm having the same troubles as you - what did you do here?

    I'm betting I will run into this problem, too, should I get so far - may I ask in advance for info on setting up the connection manually?

    I think I created the folders using File Browser, but can't remember anymore. Perhaps I should have written it down.

    I think I wrote in the name of the wireless network, set the encryption and wrote in the password. Yes. And I have to do this every time I connect.

    But I can't remember either for sure just now, as I'm in a mountain cabin on another computer.

    Hope it helps.

    I just bought this card as well, and got it working using the above steps. However, I am unable to use the 802.11n features of the card (I have an 802.11n network running on the 5ghz band and the card cannot see it). I tried setting the HAS_DOT11N_DRAFT3_SUPPORT flag to y in the config file, but that didn't fix it.

    Any thoughts?

    Thanks

    P.S. I used the latest version of the driver, 1.7.0.0 rather than 1.6.1.0 as was specified above.
