Hello, I bought Archer C2(EU) Ver3.0 router. It claims to provide full gigabit connection via wan port. With direct ethernet connection to the desktop computer I get around 300+mbps with speedtest. Whenever it's connected via router, it drops down to 50-60mbps. However the download speed does not match the speedtest. It is downloading at 9mb/s (direct connection speed is around 36mb/s). What could be a possible solution to this? A new router or call to the provider?
