I have a problem

My RB-450G DHCP-Client can’t get ip from my provider

Status is only Searching…

v.4.13


echo: dhcp,debug,packet dhcp-client on ITL sending discover with id 876984269 to
255.255.255.255
echo: dhcp,debug,packet flags = broadcast
echo: dhcp,debug,packet ciaddr = 0.0.0.0
echo: dhcp,debug,packet chaddr = 00:0C:42:55:18:CA

Please, help me


What can I do to fix this?

there are no known issues with dhcp-client on RouterOS, please check if you have not added port as slave port, port is not part of bridge. Check if dhcp-client is set on correct port.

Configuration is completely correct.

At another ISP - it works.

Could this be related to the response time of the request, when sent “sending discover”

At this ISP DHCP settings are given for 10-15 seconds (I check this by connection my laptop)

At another ISP 2-5 seconds - mikrotik works great

Note that with cable networks in particular you may have to power down the ISP provided device before swapping connected devices. Many cable modems in particular are configured to only allow access to the first device (by MAC address) connected to them after power up.
