I have problems with my internet connection speed. Thing is if I connect directly the ethernet cable to my PC the speedtest.net by Ookla shows me a download speed of almost 300Mbps. If I connect it through my TP-Link TL-WR841N router and then into my PC it shows a download speed of merely 100Mbps. So I have a modem which goes into a router in the living room which also has another PC connected. From that router the Ethernet cable goes to my PC/the router I was talking about which are in another room. What may be causing the issue? I very much appreciate your feedback.
