Based on the behavior of my network I appear to have the SPR code problem after a recent power outage. The problem I have now is that I can't seem to log-in to the switch. I know the switches IP address, but can't ping it from the AP, from an ethernet connection in the house, or directly connected to the switch via ethernet cable to laptop. I've tried using PuTTY but no answer from the switch. What am I missing?
