I just called my internet provider (who supply the router with my monthly 
subscription). It turns out that the only way to get rid of an old computer on 
my network and free up a previously used IP address is to reset the device and 
reconfigure the whole thing, including wireless setup, access control, the 
whole 9 yards.

So, I guess I will just have to edit my aliases and scripts to use the new IP 
address.

The one remaining problem, then:

How do I make knetworkmanager automatically connect to the internet, instead of 
me having to click the icon, like it did with the previous hardware?
