  2. Hi

    I followed the process exactly... it says

    KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
    make: *** /lib/modules/ No such file or directory. Stop.

    please help

  3. Hi bro,

    I followed the procedure as you have mentioned and got it working. After few days I had to re-install fedora gnome 3 again...but this time it's giving exactly the same error as it shows in the previous comment... Everything works fine until patch..problem starts at make command

    Please help

  4. @Azaruddin, you have to install kernel-devel package.

    yum install kernel-devel.

    Note that the kernel-devel package should be the same version as your kernel.

  5. Hi bro

    I have installed Kernel-devel and gcc package now and then followed the above mentioned instuction .. everything looked like working but actually wifi is still not working... however i would like to post the results of Make command... please let me know if its normal

    I am going to reinstall win 7 and fedora 15 again cause my MBR has got corrupted.. will post the results after update...

    Strange thing is it worked when i installed it for the first time...later after doing os re-installation its not working...

    One more thing i booted inially using a USB drive...later i kept few of my personal files in that drive and then removed them and did an OS reinstall... i guess that might have caused it...

    I am going to download the ISO and create a bootable disc this time.

    Wish me luck and please reply and let me know where i went wrong


  7. patch -p0 <../5_100_82_38.patch

  8. patch -p0 <../5_100_82_38.patch
    no such file or directory
    now what to do.

  9. Thanks.........It worked for me...........
    But why It takes long time to connect wi-fi. Some time requires reboot to connect, I mean connection is slower. I have dell i5 laptop with fedora 15. wi-fi works well for other machines.
