"Offering without success" means that the MikroTik received a DHCPDISCOVER from the client and tried to respond with a DHCPOFFER (to provide the lease). The MikroTik then did not receive any response (DHCPREQUEST) from the client within 30 seconds. Generally, this problem will occur if you have a switch or other device between the MikroTik and your DHCP clients that is blocking the DHCPOFFER packet or otherwise not returning it to the correct client. Alternatively, the problem may also be a mis-configured or mis-behaving DHCP Relay device.

Hence my statement that the problem is most likely a switch or other device in between your router and your DHCP client. For example, we recently had one of our FTTP locations start exhibiting this problem, because the management chassis (which functions as a switch) was dropping return traffic from our router to the client devices for new ARP entries. And we thus had to reboot the management chassis for our FTTP service.

I've seen this when there was packet loss between the wireless CPE and the AP.
