Hello All,

I use an Archer C6 router for my home network. I find the below entries every few minutes (mostly every 8 minutes). Cant get to find out what could be causing the issue. I am on the latest firmware. Any help would be of great help. Do let me know if there is any info that I can provide here.

This is causing issues when on live calls or watching live streams.

Any help please ? Is it a problem with the ISP connection or something to with the settings on the router?

Thanks!
