I was playing games on PC yesterday and realized that in every game, my ping was very bad. I restarted my R3 and after booting back up, it no longer detects my PC over any LAN port. I know the PC isn't the problem because when I connect it directly to my ISP modem, I get internet. The R3 still connects over Wi-Fi and in the R3 settings when I look at LAN devices, it recognizes that something is plugged into the LAN port but the PC doesn't show up as a wired device under device manager.
