I'm copying this to the list because it was sent directly to me... There 
are definitely many ways of "encouraging" people to change the password 
which could be explored, another example is the WAN interface could be 
disabled until the password is set. A few more thoughts on something 
like that or the WiFi disable proposed below though:

-Don't just have a feature like WiFi die without an error message 
indicating the password must be changed, again bad user experience (and 
lots of support requests)
-Make sure that the error is clear BOTH in LuCI and the CLI and provide 
instructions for changing the password (e.g. just sending an error to 
the console is not sufficient) LuCI already can detect the null password 
condition as it prompts the user with a banner to set a password, this 
could be adapted to check for a default password and the warn the user 
that some features are disabled until the password is changed
