Can You Use WiFi and Ethernet at the Same Time in Windows 10?

Windows 10 is versatile when it comes to network connectivity, allowing users to leverage both Wi-Fi and Ethernet simultaneously. However, there are some limitations and configurations needed to make this setup work optimally. This article will explore the possibilities and constraints of using both Wi-Fi and Ethernet in Windows 10.

Overview of Simultaneous Usage

Yes, Windows 10 supports the use of both Wi-Fi and Ethernet at the same time. To achieve this, you need to configure your system smartly. First, connect your Windows 10 PC to a Wi-Fi network. Then, plug in the Ethernet cable to the PC. From there, your device will use the internet from both networks simultaneously.

Requirements for Effective Use

To make the best use of this configuration, the two connections should correspond to separate internet connections. This is sometimes referred to as 'bonding' or 'merging' separate networks. Proprietary software such as Speedify can simplify the process, integrating the two networks seamlessly.

Techniques for Simulated Concurrent Use

While it is not possible to use both networks simultaneously in the traditional sense (sharing a physical network interface), there are techniques that can simulate this behavior. One such method is using a network bridge, which can make both networks function as if they were a single connection.

To bridge the networks, you can use the Network and Sharing Center in Windows 10:

Open the Network and Sharing Center. Navigate to the Adapter Settings. Select both the Ethernet and Wi-Fi connections. Hold down the Ctrl key as you click on one of the connections. Right-click and select 'Bridge connections.'

This method does not provide a simultaneous connection but rather alternates between the two networks. Essentially, you use the Wi-Fi for a while, then switch to Ethernet, and back to Wi-Fi, creating a round-robin effect. This can be beneficial for scenarios where you have multiple network-intensive tasks happening simultaneously.

Real-Time Application: Network Failover

In certain scenarios, such as having two separate internet connections from different ISPs, this setup can be particularly useful. For instance, in the past, I had to set up a network bond using two separate 3G or 4G modems on an old laptop running Linux. This allowed me to establish a combined network connection that provided failover capability, ensuring that if one ISP went down, the laptop would switch to the other connection.

However, for most users, this type of network configuration is more trouble than it's worth. It can introduce inconsistencies in throughput and may not be significantly faster than using a single high-speed connection. Additionally, if both connections go through the same router or switch, any bottleneck remains.

Best Practices for Network Usage in Windows 10

For optimal network performance and reliability, it is generally recommended to use a high-speed, stable connection. If you have a spare Ethernet port and are close to a router, prefer plugging in an Ethernet cable. When you are not physically close to a physical connection, use Wi-Fi, which can provide reliable and fast speeds in many environments.

Conclusion

While it is technically possible to use both Wi-Fi and Ethernet at the same time in Windows 10, the practical benefits are limited. For most users, sticking with one stable connection is the best approach. However, for specific situations like failover networks or environments where multiple high-speed connections are necessary, setting up a network bridge can provide a useful workaround.
