Symptom 3 — Having problems interfacing with UGA over ethernet interface.
Make sure the UGA IP address and subnet mask are set properly from the UGA front panel. Check if the UGA can be pinged from the host computer. The most frequent problem is the firewall of the host computer blocks communication. Disable the firewall and try communicating with the UGA again.
