I recently had to replace my modem/router with a Motorola Surfboard. The prior modem/router was the same model. The router picks up my HP Touchsmart desktop, Sony Vaio laptop, HP laptop, Kindle fire and Netflix, but I get an authentication problem message with the Asus. The Asus sees the wireless network and shows excellent strength, but won't pick it up. I have changed the Motorola password for my router and entered that password into the Asus via the forget screen. Any ideas what to do next?
