Okay, so today I bought a new USB adapter because the old one broke, and I noticed in general maybe 2-10 MS higher than usual, okay it's not that much right?

When I logged in to wow I had to begin with 69MS, which is about 30MS higher than usual, which is also fine I guess, but over time this number raised, and raised and now it's on 300MS, and nothing has changed with other games, still the same MS.

Also note that I have normal Home MS, it's the world MS that's just shit.

What could have happened?
