Hello there, I have an Acer Aspire 6920 laptop which is installed with Windows Vista on it. I have a Linksys wireless router from which I access the Internet on the Laptop. Nowadays the laptop is behaving very weird. I am not able to connect the laptop to the network at all. Whenever I try to connect the laptop to the network, the system gives error saying Problem with Ethernet controller. As I am not having knowledge about networking I am unable to solve the problem. Also sometime the laptop give BootMGR missing while booting. So I want to know how to solve Problem with Ethernet controller in Acer Aspire 6920. Please help.
