Hi. My router (which I recently bought) with DD-WRT firmware deson't handle the stress it should be able to. For example a few minutes ago I downloaded a new GPU driver and CSGO with 5 mb/s. What happened then was that I couldn't load any webpage including the routers interface (because it was too stressed.) I had to manually restart the router to be able to enter the interface. I have very standard optimization, not QoS enabled. If you want screenshots of something specific let me know
Hope you can help me.
