Flint 2 The interface is connected, but the Internet can't be accessed

Hi

Based on the error message, this appears to be a physical layer issue.
Please try the following to see if it helps:

  1. Replace the Ethernet cable with a different one, including the one included with Flint 2 and others known to work properly
  2. Try configuring Flint 2's LAN 1 port as WAN and connect to the ISP modem using this port

  3. Try adding a dumb switch between Flint 2 and the ISP modem
