Can't access few websites through LAN port of my WiFi router. It's Tp-Link TLWR841N. I can access all website through WiFi. There is nothing blocking the sites on my PC as I have been using this PC for a long and my earlier router had no such issues. Also I am using Bandwidth Control for the router for a specific WiFi device.
Might be a DNS problem through LAN, try using another DNS Ip if possible.
