EA6350: Set up worked fine, my nw is working, but now I can't login to the router

Question

The setup went well, I was able to configure the network wirelessly on the web-based console.  The networks are working fine (both 2.4 and 5Gz).   A few days have passed and I wanted to check out some of the other management feature of the console (checking who is logged in, etc) and keep getting the message below.  Why can't I access the router?
Your router was not successfully setup.
Follow these steps:
1. Press and hold the red Reset button on the back of your router for at least 10 seconds.
2. During reset, the router will restart and the power light will flash. Wait until the power light is solid.
3. Reconnect this computer or device to the default wireless network. You can find the wireless network name and password in the Quick Start Guide or on the label on the back of your router.
4. When finished, click here to run through setup again.
