I made a mistake installing my WR802N and now can't log in to its home screen to try to fix things. When I visit tplinkwifi.net, I get a page that says there's no internet and offers some fixes, but no way to get to the home screen where I could probably make everything right. Resetting the WR802N was no help. The mistake I made, I think, was failure to select my LAN as the internet source for the WR802N. In my Android's settings I can connect to the WR802N but without internet. The status light is always blinking, never solid on. 

"Email me when some replies" on this tp-link page needs some editing.
