I am managing a network that sporadically has network outages that present as follows
no TCP or ICMP traffic is working between any devices on the network. Two computers with valid ip addresses are unable to ping each other
UDP, ARP, SSDP, and some other protocols do seem to be successfully communicating between devices in Wireshark
power cycling all of the network switches (not router, just switches) seems to temporarily resolve the problem
The switches are unmanaged. There are no red lights on the switches or anything suspect. Just green and a few orange link lights (indicating 10/100 connectivity instead of gigabit).
What are some troubleshooting steps I can follow to narrow down the problem.
