Bought a DOS version, MY set. added a stick of RAM on my own. Running on Windows 8 for now, runs my games like a charm. Enjoying Titanfall beta with no problems.
Disconnecting as in the signal is gone at random times or....? My signal bars never drop, just the speed. Absolutely horrible on 802.11n mode. I had to switch my home router to use b/g mode exclusively so i can get stable speeds 90% of the time.

BTW, friendly reminder to Y410P/ GT 755M owners, do not update your Nvidia drivers to the 332.21 version. I used that after my fresh W8 installation, after restart the laptop screen keeps flashing on and off. Had to remove the drivers in safe mode then use the one provided by Lenovo from their website. I have no idea about the latest 334.89 drivers, but for now i am not gonna try.

Edit: forgot to thank you guys for the tips and replies. thank you very much!
