Many (most?) SOHO routers always hand out the lowest available address (as
compared to a round-robin approach), and do change addresses to given clients
under common circumstances (e.g., router restart). This is why such conflict
can and does (as I know from experience in solving such problems) happen.

But if it gets working, then it is likely to be left in place, which is why
it's a bad idea to point down that path. Much better to address the real
problem, the failure of DHCP.

None that are properly managed -- that's another Really Bad Idea.

Fair enough.
