Please get a temporary internet connection by ethernet, tethered or however is available. Open a terminal and do:

sudo apt-get update
sudo apt-get install linux-headers-generic build-essential git
git clone https://github.com/lwfinger/mt7630.git
cd mt7630
make
sudo make install
sudo modprobe rt2800pci

Your wireless should now be working.

If it does not work as expected, check. Are there any informative clues shown in the message log?

sudo modprobe rt2800pci
dmesg | grep rt2

Is this a laptop with a wireless switch or key combination? Is it set to enable wireless?

rfkill list all

Let's do some additional troubleshooting. Reboot and open a terminal and run:

sudo modprobe rt2800pci
rfkill list all > wifi.txt
dmesg >> wifi.txt
iwconfig  >>  wifi.txt
modinfo rt2800pci >>  wifi.txt

Find the file wifi.txt in your user directory and copy and paste it here: http://paste.ubuntu.com Give us the link in your reply.

EDIT: The version of rt2800pci in your pastebin is not the version that includes your 7630 device. If you have had an update to the linux image, re-compile:

cd ~/mt7630
make clean
make
sudo make install
sudo modprobe -r rt2800pci && sudo modprobe rt2800pci

Is it working now?

  • when i type the second line it says that: the program 'git' is currently not installed. you can install it by typing: sudo apt-get install git but when i type this command it says: unable to locate package git Nov 6, 2014 at 15:55
  • Please see my edit above and try again.

  • I did every thing as same as you said and finally I'm not connected to internet via wireless. Nov 7, 2014 at 7:40
  • Please recheck: lspci -nn | grep 0280. Is your device [74c3:7630] or is it [14c3:7630]? Thanks.
