Yondoo provided router, has "password" as admin pw, won't let us change it

I agree, but if we start listing every massive security vulnerability that
can be found on the intra-home LAN in consumer-grade routers and home
electronics equipment, or things that people operate in their homes with
the factory-default passwords, we'd be here all month in a thread with 300
emails.

I'm sure this ISP will realize what a silly thing they did if and when some
sort of worm or trojan tries a set of default logins/passwords on whatever
is the default gateway of the infected PC, and does something like rewrite
the IPs entered for DNS servers to send peoples' web browsing to
advertising for porn/casinos/scams, male anatomy enlargement services or
something.
