Thanks for your reply, but I can't believe that the thousands of people who buy a laptop with the AC-7260 in it should also be required to buy a new dual band AC router. Worse than that, even if that were true, wouldn't you think that the computer manufacturers and Intel would make sure that consumers know that the AC-7260 is -incompatible- with non-dual band or non-AC routers? Not only that, but think of all of the places one could take their laptop that would still be using non-dual band, non-AC routers. It would render the laptop useless in most places.
I can't believe that. I believe that it is meant to work (even if not as good) with non-dual band and non-AC routers, and no one is doing anything to fix the problem.
Btw.. my router does have the latest firmware.
