Could you please provide more details, like controller and CI (SM) logs.
Before that: Please analyse controller RCU terminator or cable in place.
And if possible connect the controller with serial cable, and do a serial FW upgrade. If possible check the desired IP is set on the controller using IPConfig tool.
Sometimes this helps, you leave ypur controller out of network and switch off the power to controller remove batteries in it, which helps in erasing flash. After waiting for 10-15 minutes, try to reboot the controller resuming power supply.
