Just curious. How does Asus firmware force a browser window to open?

When you plug in an ethernet cable a browser window/tab will automatically open up and request a login to the router. How does this happen?

I've never seen that happen on any computer I've ever used.

When I install new firmware and it boots up I get this opening up when I plug in a LAN cable. So how does it just automatically pop up in my browser?

OK, that makes more sense. When you update the firmware the already open web page will wait for a while and then refresh itself. If the router doesn't have a connection to the internet it will display that error message.

If you want to disable this behaviour and just have the browser return the normal "not found" or "unable to connect" error messages log into the router and go to Administration > System. Turn off "Enable WAN down browser redirect notice".
