This is exactly the sort of mess that 'whereami' is meant to handle,
first through detecting the situation and second through reconfiguring
services to suit that location.
There are a bunch of other tools in Debian as well, but I naturally
recommend my own one :-)
I personally connect regularly to about 10 different LANs - only one of
which is Wireless, most provide DHCP and some require fixed IP
addresses. Once I have 'whereami' configured for each new location I
simply open the lid on my laptop and it all 'just works'.
