The only time Chrome's over-zealous security has even shown up for me is when it doesn't let me login to WiFi that requires a login page. Which happens a lot. Oh, and maybe once the site in question had an expired certificate and I had to use another browser to access it. Wonderful.
This is a problem on Firefox too now. It is due to the new ability for the browser to remember that pages are HTTPS only. For these routers, I generally use example.com as a non-HTTPS website to hit the login.
