I can easily browse the internet, stream youtube and netflix and download files at a relatively high speed but I get ridiculously high ping in every game reaching up to 20000ms. I've tried different wifi adapters, updating drivers and other methods but nothing has worked. It can also sometimes become painfully slow suddenly at any time of the day and even disconnect. No other PC in my house has this problem. Any ideas?
