Does Logitech G915 work with Multiple Devices?

Is it possible to connect the Logitech G915 keyboard to multiple laptops or PCs at the same time?

The answer is yes

The ability to connect one keyboard to two laptops simultaneously (or near simultaneously) makes it easier to switch between the two. I have two laptops on my desk and without this capability, I have to switch the USB dongle or Bluetooth connection every time I want to move from one laptop to another. Very inconvenient indeed.

Fortunately the G915 keyboard solves this problem. How does it do this? Read on to learn more.

G915 Wireless Technologies

The G915 supports two wireless technologies: Lightspeed and Bluetooth.

Lightspeed is a Logitech-only wireless access technology, while Bluetooth is an open standard built into all new laptops and mobile devices.

Lightspeed wireless requires a proprietary USB dongle. The dongle is essentially a receiver that communicates with the peripheral using a specially optimized wireless protocol. Since it is proprietary to Logitech, the company has not embedded this into every laptop (unlike Bluetooth). Hence a separate dongle is required.

Bluetooth is a short-range wireless technology standard that is used for communicating between devices over short distances. Bluetooth is everywhere – in phones, tablets, laptops, smart watches and more.

One characteristic of Bluetooth is that it only allows you to establish one wireless connection at any time. To connect another device to the keyboard for instance, you have to un-pair from the first one.

So how to connect the keyboard to two laptops?

Here’s the trick:

  • You can connect the G915 to one laptop using Bluetooth.
  • Connect G915 to the other laptop using Lightspeed. Make sure this laptop has the Lightspeed dongle plugged into its USB port.

The keyboard has a Bluetooth and Lightspeed button. Simply press the button to switch or toggle between the two laptops.

Now you don’t have to manually pair over Bluetooth with one or the other laptop. As well, you don’t have to remove and reinsert a USB dongle.

In practice you can switch between more than two computers using Bluetooth. However, you will have to pair with each separately. This is a manual process that has to be repeated every time you want to connect.

💡 The G915 also works in wired mode, so you can have three connections where you don’t have to configure anything.

Note that when it is plugged in, the G915 will only work in wired mode. When unplugged, you can switch between two wireless modes: Lightspeed or Bluetooth.
