I already change to other router as the issue is very annoying for me.

@Kevin_Z Hello, I'm using a LAN cable to connect. My Dos Protection is disabled, but it still occurs. I tried a different router and it didn't have the same issue. Should I try to flash 3rd party...

Hi, I'm having some issue with my Archer C6 which is when every time I open the qBittorent, the internet light will become red. The affect is every website having slow respond during the that time....
