If you have more than one network adapter, then if active they must be connected to different subnets. If single subnet is your case, use only one connection. It is the task of network awarness process that helps Windows operating system to connect properly. For access to Internet, there is test procedure, that enables to detect functional access to definite web page and DNS response. Regards Milos
