I have Subject switch, and one of the led lights, port 1, is blinking
off and on. The connection to port 1 cannot be seen from the other two
PCs on my LAN. The other two PCs can see each other. Up until recently
this 3 PC LAN was working fine.

I've reset the switch several times, and nothing changes. I rebooted the
PC on switch 1 and it hasn't changed the behavior. Checked the
connections and they seem solid. Switching the PC port to another port
produces the same blinking. Comments?

I had a 5-port D-Link switch a few years ago that did the same thing.
The condition was permanent; the switch became a 4-port switch. I
guess it's lucky that you only need 3 of the 5 ports, so you're still
in good shape.

The connection produces a blinking light on any of the three ports I've
plugged it into. The other PC works fine on any of these ports.

Oh, ok, you didn't mention that. In that case, I'd say the likely
culprit is the Ethernet cable. If swapping or replacing the cable
doesn't change anything, then the Ethernet port on that computer has a
problem. In that case, if it's a desktop computer it's easy to add or
replace the Network Adapter. If it's a laptop, go wireless.

The good news is that the switch is fine.
