My friend, who has same issues as yours for the past month, was still able to stay login in msn while she got disconnected from game. So it's very likely to be server sided issue.
Many programs aren't affected by short internet outages, from my experience if my internet cuts for just a second, vindictus will disconnect while everything else stays connected.

Keep a ping to google going while you game and see if you time out when you disconnect. Your modem might say four bars even if there are some internet problems going on.
^ lets first identify if the problem is truly vindictus-only or affects other things as well. I had a friend who was randomly disconnecting from IRC every 4-8 hours, and it turned out it was because the router wasn't fully compatible with their internet connection.

ping www.google.ca -t[/FONT] will have your computer ping google non-stop. It will say Request Timed Out or give you very high values (>1000ms) if you are experiencing connection problems.
If you are experiencing outages, and you have another computer in the house, run the pings simultaneously to see if it's the connection (both computers time out) or just yours (yours times out while the other stays connected)
