I'm using windows 7 ultimate x64,my ping is usually normal(20-25) until someone on the other computer on the network start downloading or just start watching videos, it keeps fluctuating between 25-400, it seems like a ISP problem but I don't know what to do maybe you guys can help me.
i kinda lol'd xD, cause i have always shared internet with 2 computers, and is a comon fact for me, that if some1s watches videoso or downloads, i lag.
I duno, because i'am to lazy to search about it, but there is a way to share the internet in equal parts, so you won't lag.
Ex: you have a 4mb connection, you configure the internet to give 2mb for your computer and 2mb for the other computer.
If some1 knows anything about this stuff, just share your knowledge
