I have an Asus RT-AC68U with Merlin 378.55.
All my hardware get a fixed ip-adres with DHCP Manually Assigned IP in the router.
The probleem i have is that my phones in the house use 5Ghz and when the signal is lost it switches to 2,4Ghz.
In DHCP-Server I put my phone mac adres with ip: 192.168.0.14 and that works fine.
Then my phone lost 5Ghz wifi so it switch to 2,4Ghz and then it get an other ip-adres x.x.x.229 and not keeping the same adress. Mac adres is the same for both bands.
The log file

I think the problem is that the router still thinks that x.x.x.14 is still in use the then gives an ip from the pool.
Problem is that i use Domoticz and I use that ip-adres to check if the phone is at home and becasue the 229 adres is random a can't check on the second ip-adres.
Is there a way to force the phone to always use the same ip-adres.
