[Nathan <nblomquist+ubuntuone@xxxxxxxxx>]

I was recently trying to bring an old laptop back to life.  It contained
a MiniPCI Ralink RT2500.  It had Maverick installed and the wireless
worked.

I then started trying to install Trusty 14.04 on it.   The wireless was
constantly disabled in live CDs and I tried a bunch of workarounds that
failed.

I finally found the linux kernel bug report that was linked in this bug
report and found that it was implemented in kernel 3.14.18 (just
recently).

So my workaround that finally fixed the issue was to install the 3.14.18 utopic kernel from here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.18-utopic/

Specifically for me it was the i386 debs:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.18-utopic/linux-headers-3.14.18-031418_3.14.18-031418.201409060201_all.deb 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.18-utopic/linux-headers-3.14.18-031418-generic_3.14.18-031418.201409060201_i386.deb 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.18-utopic/linux-image-3.14.18-031418-generic_3.14.18-031418.201409060201_i386.deb

It would be much better from a long term standpoint if these changes
were backported to 3.13 and put into the longterm kernel of trusty.


Thanks

  WLAN-Stick or Blacklist and use the Windows XP Driver with the
  NDISWrapper.
