Hello!I have been running Windows XP in 6 months on this box without errorsand windows 7 Build 7100 (RC1) in one month and now ive got some strange connection errors like thisApplications dont get allowed to start new connections.A case of this is:Iwhere talking with a guy on irc and irc is never closing its connection.Then a guy asked me for help in a application called "Teamviewer" and when i opened it it said i didnt have connection, but i could still talk at IRC.Then i opened it again like 5 minutes after and it worked perfect.Also im almost never able to surf cause IE dont have a static connection and open new every time i update or change page...My friend had this error in vista to... i think its a very old error.Ihope you can help me and thnx for all god replys.(Also! im connected with a something wireless modem from "Bredbandsbolaget" and a wireless linksys usb connector thing.)NO ERRORS WITH XP so dont say its cause of hardwareAlso all drivers is correct and updated

What was the error?

that applications almost never can open new connectiions xD

That isn't an error. An error message would accompany an error. Can you try disabling IPv6 and see if you get the same issues?
