I have a dual booted configuration, with the default Windows 8.1, and the latest Ubuntu 14.10 64-bit.
The wireless network is very slow. On Windows 8.1, it works like a charm, while on Ubuntu, I get almost 1/8th of the original speed.
However, when I use Ethernet, I get the full download/upload speed that I'm supposed to have, just like Windows.
When I switch from ethernet to wireless, all the websites suddenly stop loading, and apt-get takes forever in starting the download.
Following this script, here is the output :

########## wireless info END ############
I have followed almost every solution mentioned here on Ask Ubuntu and other websites, but neither of them seems to work.
Asus support has let me down. When I contacted them :
For your case, that may be caused by lack of driver with it. (driver is not compatible with linux Ubuntu )
For your information, according to the support site: http://support.asus.com.cn/download.aspx?SLanguage=en&p=3&m=G751JM&hashedid=H1PGPvZ0ODsnDxTf
There is only win8.1 version driver for the notebook G751JM
We don't recommend user to use linux Ubuntu OS with G751JM product.
We passed your mail to technology R&D team, let them check and consider to build it in the future.
Sorry for the inconvenience. Thank you very much for your understanding
Thank you for your support Asus product. Wish you have a good day.
How can I have a good day, knowing that the laptop I bought from my own savings is not compatible with my most used OS?
I will truly appreciate it if someone could point me to another solution for this problem. Is purchasing an external wireless network card is the only possible solution?
nohwcrypt=1, which means it's already disabled. That's because I've already tried this solution. – Abhishek Goyal Jan 21 '15 at 22:00
