Network Topology Question

[sukhusukhu]

Hi all,

I am setting up a home network and running into a few problems. The topology I have set-up is attached:

When I connect PC3 to the ethernet switch directly, I does not work (no internet). The ethernet switch light turns on briefly for the port I connected, and then turns off. This repeats for a few times and then stops. However, when I connect PC3 to one of the wireless routers, it works just fine. Does anyone know what might be going on?

Thanks!

what eternet switch is this mode and IOS running on it, seems to be Negotiation issue - but we need  to know is that switch, and possible post the running config of the switch.

Thanks for your reply. I am not sure how to find out the mode and IOS running on the switch. Its a very old switch that I found in my garage, here is the model number: EFAH05W
