This RAP will be the third time I have replaced it. Last time I installed a grounding wire and grounded it to the ground. The AP was up for about three months until a lightning storm passed through. Later that night clients began to complain. This is a regular thing during the summer months when storms are the norm. The RAP is receiving it's power over PoE. The power brick is connected to a UPS. Do you think the surge is still coming across the ethernet cable to the AP? What are your thoughts on this?
