They don't, and it doesn't !
IME, typical home routers tend to give the local lan a TLD like ".lan", and 
when offline have a nasty "user friendly" feature or screwing with the DNS to 
point the user's browsers at something like router.lan which resolves to 
itself. Thus the router only needs a cert for router.lan - which as Adam points 
out is worthless for security since anyone could extract the private keys from 
a firmware update image.
And in practice, I doubt that the cert ever gets renewed - by the time it 
expires, the vendor will consider the model obsolete.

As above, I doubt if many, if any, actually bother to update the cert.
