I have been searching this board for this problem and have found posts going back a year that say the Linksys smart wifi site is down. Has it been down consistently for an entire year? I just bought this EA3500 router and the last step in the installation is to access http://www.linksyssmartwifi.com, supposedly where I set up things like a guest account password. All I get is 502-Bad Gateway. Having just bought this router yesterday, I don't think I should have to pay for a support call to resolve this. I'm hoping for a resolution in this forum.
