[lug] TP-Link Router Q.

[Stephen Queen]

Years ago I was running into similar problems on a number of routers
(openwrt). I can't remember the exact details, but it had to do with the
file buried in /var that kept track of assigned ip address. When the lease
on the address expired, then the address could be re-assigned.  I could
also go into the file with an editor, and delete the entry, and if memory
surves me correctly, I had to restart the dhcp server.
