Same here, I didn’t change VLAN 911 settings at all.
Tried at method e.g. changing MAC address
still cannot obtain IP.
It happens recent days, each time powered down my router and have powered back up, static IP cannot obtained by DHCP anymore.
I could get a IP by chaning MAC adress till yesterday, but not working now for today.
Maybe related to this change?
I could confirm I was using the IP pool from 149.18.87.xx only.
