Hi,
Haven't heard much about this myself, and make sure to try the latest drivers from the ASUS G750JS download site if you haven't already.

Have you tried comparing with other wireless environments/routers?
Anyway, if you don't get better suggestions, you may want to discuss with your store or local ASUS support to see if they have heard of this issue or think there may be some problem with your system.
It may not be worth trying, but consider checking your bios version and asking them if you should flash your bios.
