Recently I got a new problem.
It started about 4 days ago.
And it is about MSN Messenger.
That program keeps disconnecting over and over.
When MSN is up and running, it doesn't takes long time until it disconnect.
It can takes a few minutes, and then it lost the Internet connection.
A message comes up and it says: "The connection to NET Messenger-service has been interrupted. Reconnection in xx - seconds"
The seconds is counting down, and MSN automatically reconnect in between 30-50 sec.
And then MSN is up and running again, for a few minutes till it disconnecting again, and start all over again...
And it keeps doing that all the time.
So it is impossible to have a video-chat, or even voice-chat.
It's so annoying.
The very same problem is on my 2:nd and 3:rd computer too.
I have a router (with build-in firewall).
But this have been working perfectly before, with no problems at all.
But suddenly it starts changing it's behavior.
I also have Skype, and that program is not disconnecting as often as MSN does.
But as the matter in fact, Skype is also disconnectiong now and then, but not so often.
I also have Yahoo, AIM and ICQ too.
And these programs disconnect temporarily, now and then.
But if I use Trillian for all these programs, it's working a little bit better (I think).
However, MSN Messenger is the biggest problem!
It is USELESS to use it now!
I have scanned the computer for maleware, spyware, virus and everything.
I don't know what the problem is.
Can somebody help me? please.
