This includes downloading files from the Internet using your web browser, surfing the web, chatting with your friends using an instant messaging program and etc. Basically a network adapter that has the higher link speed will be assigned a lower metric and the network adapter with the lowest metric in the routing table will be used.ĭo take note that only applications that use the Internet Protocol will use the network adapter with the lowest metric. Microsoft has an article that explains the automatic metric feature in Windows and how it assigns the metric for a network adapter based on the link speed, hop count or time delay. The values in the metric column are the most important pieces of information in a route table. By typing the “ route print” in command prompt, you get to view the route table that contains information such as the interface list, network destination, netmask, gateway, interface and metric. In an IP network, a routing table is a set of rules that determines where the packets are directed to. It is not entirely true that there is a rigid rule whether the Ethernet or WiFi adapter will always be used when both are connected to the same router/gateway. Moreover, there is a higher chance that the wired connection these days has a faster connection speed up to 1Gbps while the fastest wireless speed at 1.3Gbps with the latest 802.11ac standard is hard to achieve.Įven if your computer’s BIOS doesn’t support switching of networking adapter automatically, Windows actually has a built-in algorithm to decide which network adapter to use for best performance. This is logical because a wired connection is often more stable than wireless as it is prone to interference.

Some BIOSes on branded computers such as HP have the ability to automatically disable the wireless when a wired connection is being used. The best way is to manually disable the network adapter that you don’t want to use from Network Connections in Control Panel. Since both adapters can be simultaneously connected to a router, you might wonder which network connection your computer will use or will it use both at the same time? Obviously having multiple networking adapters connecting to the same gateway is unnecessary because it may cause unwanted routing issues. It is common to find two networking adapters in a notebook or in an all-in-one desktop which are a wireless and wired connection.
