Lag

[Yerland]

I recently got a new computer, its better than my old one but my ping has gotten worse. On my old computer I normally got away with about 200 ping and 0 loss and lag. But on my new computer I get a ping of 250+ with lag and loss at 5-10%. Now this is making fighting impractical, and quite frankly I don't understand why my ping has gotten worse.
I was wondering if it's a problem with the server or is it definitely on my end. and if it is definitely on my end does anyone have any suggestions and how to improve my ping.

Edit: right forgot to say anything helpful at all.
I'm using the same cable for internet so no to the wireless.
