Thunderbolt to Ethernet (T2E)
Thunderbolt to Ethernet functionality allows the Thunderbolt port to act as an Ethernet interface.
Tip
QNAP recommends using Qfinder Pro when configuring Thunderbolt to Ethernet.

connectivity problems when connecting to Windows. Thunderbolt 3 connections are
unaffected.
