Your router and PC both store cached network data that builds up over time causing slower speeds and higher ping. Most people never clear either one. Restart your router properly from the admin panel at 192.168.1.1 then open Command Prompt as administrator and run ipconfig flushdns, netsh winsock reset, and netsh int ip reset. Restart your PC after. Two minutes and your connection is working with fresh data.#dnscache #routertips #pcoptimization #internetspeed #raptechpcs
