After I installed windows 7 build 7057, sometimes when I turn on my computer, I discovered that I had multiple connections for the network and I cant access to the Internet. In fact, I only have 1 network and 1 workgroup. I have a very simple network with few computers connect to the same router. I cant delete it and the only way to fix it is to uninstall the whole network device and reinstall in device manager. It happens more often recently. This is kind of annoying. Anybody knows the solution to this or anyone has the same problem???
