Wifi internet help needed
Solution 1:
I suspect the most productive thing you might try is to compile the backported driver from kernel version 3.13. Please get a temporary wired ethernet, USB modem, tethered or any reliable internet connection. Open a terminal and do:
sudo apt-get install linux-headers-generic build-essential
Download this file to your desktop: http://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.13.2/backports-3.13.2-1.tar.xz Right-click it and select 'Extract Here.' Now back to the terminal:
cd ~/Desktop/backports-3.13.2-1
make defconfig-wifi
make
sudo make install
The process takes some time; please be patient. After it completes, you may get a warning about signing which you may safely ignore. Reboot and let us have your report.
I understand you may have tried several techniques. Do you have a parameter file? We ought to see what is in it and decide if we still need it:
cat /etc/modprobe.d/rt2800pci.conf
