router rebooted

You mean factory reset? That's rare and exceptional. All DHCP settings, incl. reservations, held thro' reboot.

I think this thread got onto enterprise networks when as I understand it the OP was a home user.

All these problems mentioned regarding corporate and enterprise networks, well, quite simply the network team should just be sacked for incompetence -- assuming they are claiming to be an IT professional -- if they do not know how to recover from a DHCP server failure or how to configure a mix, everything mentioned here should be known by anyone worth their salt who is a network admin in either networking hardware or the windows field.
