Just a couple of notes trying to clarify this often over-simplified
 world of "bogus" or "valid" certificates.

I don't know of browser that accept troublesome certificates
 without warning; the warning that must be issued by the browser
 are always matter of local setup of browser, maybe of default
 setup of it if user has no changed it.

"bugus" certificates give the impression that are fake
 certificates; they are self-signed certificates, so are
 "valid" by definition. Often there is confusion about
 the "validity" of certificates.

The self-signed certificates that the rogue router show
 are valid but fake; as a fake banknotes they contain textual
 information that indicates not the real but a different issuer.

An authentic certificate by a commercial site is
 normally signed by a commercial certification

Ending this boring explaination; when the
 browser open a window about certificates,
 read it with great attention and triple
 check the origin if it is self-signed.

Not all self-signed certificates, or certificate
 signed by a unknow certification authority are fake.

This is often the case of poor organizations
 (as, for example, the Winston Smith Project...)

As always, keep the brain attached.... ;)
