I've fixed the internet connection problem

If you've been experiencing internet dropping, hanging, ect. on Vista, you're
not alone. I was ready to throw the thing in the trash. I finally fixed it by
going to the Network and Sharing center, click the View Status on the
connection, click Properties and then uncheck the QoS Packet Scheduler, the
Internet Protocol Version 6, and both Link Layer Topology choices. Then click
OK, restart and enjoy your surfing! Hope this helps. Let me know.
