We are having this exact issue on the Oasis server. The two of us are logged in with a Linksys wireless and Comcast cable modem, which has worked fine for years. Now while we're playing the ping goes up, we get 10-15 packet loss, and then it comes back to normal. This repeats every 4-5 minutes. While it is happening, we can't do anything, which really is a drag during fights. Comcast of course said their cable modem was fine, so I went out today (oye, the stores were nuts!) and bought a Linksys E3200 wireless router. And of course, we have the same problem.
