Why Is My Download Speed Slower Using Wireless Than Hardwired?

Networking - performance

Many factors can have a negative impact on wireless network performance, and these factors may result in slower downloads when using this method of connectivity. Hard-wired connections usually provide a more robust and consistent connection.

Background

Before wireless technology became common, computer network connections were generally made using cables.

Although wireless networking provides flexible connectivity without cables, environmental factors, distance between devices and various other issues can all result in reduced or inconsistent performance.

Each wireless router or access point also only has a finite amount of bandwidth to share between connected devices, so if several machines are all connected wirelessly there is less bandwidth available for each device.

Resolution

You can take various steps to improve wireless performance, including experimenting with different signal bands, adjusting positioning of wireless devices and using more powerful wireless antennae.

Alternative

If you require faster and consistent speed, and the physical locations of your equipment are suitable, you could consider switching to a physical connection using a cable.
