dhcp not working for some clients

Hi!

Suddenly, some computers (seems to be pure coinsidence, i.E. my wife’s notebook doesn’t get an IP, mine does, we’re both connected to the same wifi)

Message in mikrotik log is (for example):
default offering lease 192.168.1.90 for 28:E1:4C:97:7B:D3 without success

I found out something:

default offering lease 192.168.1.90 for 28:E1:4C:97:7B:D3 without success
dhcp lease changed by admin
default assigned 192.168.1.103 to 28:E1:4C:97:7B:D3


When the assgnement is static (.90) it doesn’t work. When I switch to dynamic (pook .100-120) it does.
When switching back to static it works once, then it starts failing again.
When in dynamic range, the GUI is garbled somehow, see picture (The D field to disable is dysfunctional and in the wrong place):

OK, it seems to be related to the ‘always broadcast’ option. All clients that had this option enabled started suddenly showing these problems. I checked in older backups and the options were the same before.. so something must have happened.

you shure about 90 adress? its free? router have 1? dhcp starts from 10 - 90?

Sure, now with ‘always broadcast’ disabled, everything ist working like before
(router is .1, dhcp pool is 100-125)
