My laptop keeps connecting to the wrong network on startup...:s?

I had the same problem and it gets really annoying. I managed to find a list of networks that my laptop connected to. It had a list of ones I used when staying with family, at work etc and included BT Openzone and BT Fon. I deleted the two BT ones. Find 'Manage Wireless Networks' in your Network and sharing Centre on your laptop. It should come up with a list of networks your computer will automatically link to. Delete BT openzone. That should stop it.

Right click your wireless network, click properties, make sure connect automatically is checked and that connect to a more preferred wireless network is not. Then right click the network you don't want to connect to and make sure that connect automatically is not checked.

Also if your home network has a "hidden" SSID make sure that you check the Connect even if the network is not broadcasting it's SSID under that network's properties.

The other answer about deleting the profile will also work but it will not set your connection to default.

Perhaps you need to repair your connection! click on Start..... click on Conect to..... chose all, then click on the one you want to use then click on Repair connection. Hope this helps
