I have upgraded my router to Asus RT-AC87U.... I was not able to log into the router from my computer so I tried using my Lab top to see if it was the router or the computer. From my Lab Top I got right in and updated the firmware on the router and set the network up. Router works great. I am on the internet with my desk top (main computer) but still can not log into my router with it. What setting on the Desk top do I need to change?
