Problems with manually Assigned IP

[SP2005]

I have problems with manually assigning IP to my devices.

When I in the "LAN - DHCP server" settings, try to give a device its own IP, most of the times it does not get its own IP but some random IP.

This is from the LAN - DHCP where I have set my OnePlus6 to 10.0.0.110

This shows that my device gets a random IP and not a Manual IP.

what can I do ? I really need to have some of my device keeping there own IP.


My router: Asus RT-AC68U. Version 384.16

That device may still be clinging to its old/prior DCHP lease!

Can I force a DHCP lease or do I have to wait ?

If it's a Windows client...

ipconfig /release
ipconfig /renew

I just simply reboot the device and the router and all works as intended.

Be sure the device isn’t using any kind of MAC randomization. You can usually force a lease DHCP refresh by putting the device in and out of Airplane mode (or toggling WiFi off and on). YMMV.

This is what I do when I am faciong the same situation as yours:

killall dnsmasq
rm /tmp/var/lib/misc/dnsmasq.leases
service restart_dnsmasq
