I'm unable to update my ID14 and 218. Tried on 3 PC's with v37, on all 3 both devices are found but nothing happens. I even tried with 218 to connect directly using crosscable and using static IP's but after finding and listing it in device manager nothing happens. Strange everyone is reporting upgrades without issues. Firewall disabled etc so i'm sure nothing is blocking..

EDIT: found it, disabled igmp-snooping on the interfaces connecting 218 / ID41 and PC. worked.
