Computer is switching to a different network?

Ok my computer connects to network 1 (the only network i have) whenever i restart the router and my computer at the same time..BUT after about 20 minutes my computer auto switches from network 1 to network 2...I dont have a network 2 and when it switches like this it wont connect to the internet...so the only way to reconnect seems to be to restart the entire network/system. I have no clue what to do about this...and when i try and connect to a different network when its on the imaginary network 2 it says "no networks available" So..any ideas on how to fix this?

Computer is switching to a different network?
Go to my networks, select the network you don't want and select " connect manually"


The network will be only ON DEMAND





1. If using the Windows Classic Start menu, click Start | Settings | Control Panel. If using the default Windows XP Start menu, click Start | Control Panel.





2. Double-click the Network Connections icon to view network connections.





3. You may have several connection options listed. Right-click the icon for "Wireless Network Connection" and choose Properties.





4. In the Wireless Network Connection Properties dialog box, select the Wireless Networks tab.





5. If the "Use Windows to configure my wireless network settings" is not checked, third-party connection software may be in use. Consult that product's documentation to determine how to disable automatic wireless connections. If the "Use Windows to configure my wireless network settings" is checked, then continue with the steps below.





6. Under Preferred networks, highlight the name of the network to which you plan to connect and click Advanced.





7. In the Advanced dialog box, click "Access point (infrastructure) networks only".





8. Remove the check mark from "Automatically connect to non-preferred networks".





9. Click Close.





10. Click OK.





11. Close the Network Connections window by clicking the X in the upper right corner of the window.

Good luck
Reply:It sounds like you have more than one network interface (i.e. wireless and and ethernet card). Let's assume that you use the ethernet card for Network 1, and that it has problems or times out after twenty minutes. The PC then tries to connect on the second interface, which looks to you like Network 2. Try disabling the second interface, then you can troubleshoot the timeouts or disconnects on Network 1. Hope this helps...
