@thebigbeav, I suggest connecting a LAN client directly to the LAN port of Balance One Core. This helps to isolate which part is giving a problem when the problem occurs again. You may proceed with the test below when the problem occurs:
- Perform Network Capture at http://[LAN IP]/cgi-bin/MANGA/support.cgi > Network Capture > Start.
- Ping the directly connected LAN client and an active LAN client who connects to the switch from 192.168.101.x or 192.168.102.x. Allow 5-6 pings will do.
- Network Capture > Stop > Download the Network Capture.
- You may open the Network Capture with WireShark to confirm the ICMP request from 192.168.101.x or 192.168.102.x sent out from LAN interface and the ICMP reply received from the LAN clients.
You may contact your point of purchase if you need further help.
