i tried running a switch but it did not make a difference.. i tried running it (with PC and controller) from the modem and router both, neither worked/recognized the pi in arp-a or ping, nothing seems to be powering up the led light on the ethernet port of the pi.. i even removed the router completely and plugged just my PC and the controller into the modem ports 1 and 2, the pi still isn't found..
feeling so lost.. any suggestions please..
