Curious as to why DHCP server seems to assign then, moments later deassign…see screen shot.
Best will be to sniff the network and analyse the packets with something like wireshark to see what is happening, problem might be caused by client side
Not sure I am following…is not the client side I believe…I want to say a bug! I have wireshark installed…will try having a look.
I have been watching the server and discovered it’s setting short leases of approximately 7mins. That seems like a bug. How to set leases to a greater period like 7days? The only other choice is to make static. Looking at the screen shot I realize that particular device was sleeping, while DHCP continually issuing random short leases.
Check the cable and intermediate equipment. I had this when the cable was damaged.

You can set a longer DHCP lease time in the DHCP server settings. I have mine set for 1 day (1d 00:00:00).

Found it…it was on the general tab, and I was trying to edit the lease time on the active tab.
