I am wanting to put a new router with my Arris SB6141. When i have just the Arris hooked up to the PC im getting 1,000 mb/s (with all lights blue). if i need wifi I hook my old netgear router but the speed at the PC drops to 100 mb/s( the last indicator blinking red). ( im telling speed from the connection information in the Linux tool bar) Id really like to be able to leave a new router hooked up and maintain the 1,000 mb/s speed to my PC.My question is will the asus ASUS RT-N66R or the RT-AC66U allow my modem to continue delivering 1,000 mb/s to the PC or will all routers kill my pc speed? I dont really need blazing fast wifi but I do for my PC. Thanks for any help you may be able to give~
