I can barely use my computer because I can't play games or download anything because my ping is so high (cmd ping test shows 800-900 or request timed out) and my download speed is only 50-300 KB/s even though it's atleast 1-2 MB/s on other computers. My computer is connected to the router with an ethernet cable. The router is a Huawei B593. Can someone please help me with this because I have tried everything I know of and I'm getting frustrated.
