I recently got high speed internet through CenturyLink, and it was working great, but a few days ago my computer suddenly lost the connection. This has happened once or twice before, but restarting my computer or unplugging the modem for a little while solved the problem. Now my computer doesn't seem to be registering a connection to the modem. Xbox Live is working perfectly, so the problem seems to be with my computer. I also tried different ethernet cords, so that isn't the problem.\n\nI'm now using my dial-up connection. I've been searching for possible solutions but I just don't understand what the problem is. I believe my network adapter is Realtek Virtual Adapter but it says it's working properly. In my device manager, the only problem is there is an exclamation point next to Audio Device on High Definition Audio Bus, but that probably has nothing to do with my internet (and my audio is working). Here is my information:\n\nSystem:\nMicrosoft Windows XP\nProfessional\nVersion 2002\nService Pack 3\n\nComputer:\nAMD Phenom(tm) II X4 945\n\nNetwork Adapters:\nDirect Parallel\nRAS Async Adapter\nRealtek RTL8168/8111/8112/ PCI-E Gigabit Ethernet NIC - Packet Scheduler Miniport\nRealtek Virtual Adapter\nWAN Miniport (IP)\nWAN Miniport (IP) - Packet Scheduler Miniport\nWAN Miniport (L2TP)\nWAN Miniport (PPPOE)\nWAN Miniport (PPTP)\n\nWhen I got disconnected, my high speed connection was no longer listed under network connections. While looking through network adapter properties and following some suggestions from the internet, suddenly an LAN connection popped up with an x saying it was disconnected, and I'm not sure what I did, if anything. It says "Local Area Connection 2" and I can't seem to make it work either. I don't remember if it's the same one as before, and since it says "2" it seems new? I think Realtek Virtual Adapter was missing from the device manager list while I was first poking around, and popped up at the same time as this second connection.\n\nThank you for your help.
