RT-AC68U sending a *lot* of unknown traffic to internet

[netgem21]

Hey!

Every so often my RT-AC68U completely saturates my 700k upload connection, transmitting something to the internet, rendering my network mostly unusable with high latency and dropped packets.

To illustrate, here are some screenshots of the traffic monitor:

Upload speed is saturated completely.

However nothing is being sent from any of my wired clients...

...or wireless clients.

What could possibly be going on here? It lasts for usually about 10 minutes, stops—at which point speeds return to normal, and then starts again.

Any help would be greatly appreciated. Can't get a stable connection anymore without this interrupting me! Apologies for the massive photos, by the way!

Thanks in advance

Don't apologize next time. Trim 'em down, please. Take pity on mobile users.

How you figure that? The last 3photo show no network activity corresponding to the Primiary LAN time stamp.

What version of firmware are you using and have you done a full reset on the router?

Are you using VPN? I had a similar situation (no traffic in wired/wireless) but I'm using the VPN connection, so I know the traffic was from my VPN connection.
