Hello! my Archer C6 suddenly started to lose packets, I rebooted it, cleaned it, changed cables, moved it around, but it still lost packets, and the modem's cpu load fluctuates a lot, between 2% and 80% without being used, is that normal?? when I connect my pc directly to my ISP modem, I have 0% packet loss, please help me :( I tried everything...
