Ross of OttawaTried using a short expiry for leases, and let them regenerate several times, but luck.
The reserved IPs list is still not letting me remove items, or change them.
I see one reference says changing the hosting address will clear the DHCP static reservations list.
Ugh, my SO is on a video call just now, so will wait until end of day, and see if I can clear out that list.
If that doesn't work, a factory reboot, and DSL reconfig etc will be last resort.
