Logitech Unifying Receiver: Interference Troubleshooting

Own a Logitech wireless product but having issues with sticky or delayed keyboard or mouse responses? The solution may be simpler than you think.

I myself own the Logitech Wave K350/M510 keyboard and mouse and recently found myself suffering terrible lag and stuttering keystrokes while using them. I turned to the internet for answers and found that the issue may be easier to solve than you think. The issue is wireless interference and the solution is as simple as removing the sources.

Sources of Interference

Cell Phones/Tablets/Mobile Devices

Keep your cell phone near by? You may want to think again and place it somewhere that’s not between your wireless device and your PC. I have noticed that simply removing my cellphone from this path of connection greatly enhances the responsiveness of my wireless input devices.


Ok, so I am not sure how often this would be a problem, but the fact is that Logitech’s unifying receiver actually runs on the 2.4Ghz range. This means that anything else in that spectrum could potentially conflict. Microwaves are known to cause temporary issues with wireless routers in this spectrum and thus could also cause issues with your device. So if you notice your mouse stuttering while someone is heating up some food, you may want to consider relocating your desk or moving the microwave.

Your PC

Yes, you read that correctly. The receiver may just be too close to your PC. According to a forum post on AnandTech that referenced this, multiple posters suggested that the components in your PC may be generating RF interference. This actually may be the exact issue I was having as using a USB extension cable and moving the receiver further away from the tower I am now getting a much more consistent operation with fewer hang ups or hiccups. This is probably why they include those 3ft extension cables in the combo boxes. It’s to make sure you can get the receiver out away from the tower they assume you are plugging into. So, if you have that cable on hand, give it a shot, else spend a few bucks to grab one to see if it fixes your issues.

Other Issues

Too Close To The Receiver?

In years past of using this combo set I ran into another issue. It appears that it may be possible to be too close to the receiver. As strange as that sounds I have encountered issues when I am within a foot of the receiver but moving my keyboard and mouse further away lets everything work no problem. I am not sure how much this may be circumstantial or anecdotal and what the science behind it would be but moving the receiver away from your tower (as mentioned above) but also a few feet away from your device may be worth a shot. I have noticed improvements using this method as well.


Wireless devices may be complex and leave few options for troubleshooting, but these are the ways I know of how to help troubleshoot the Unifying devices I own from Logitech. If any of these methods helped get your device working, feel free to let everyone know what worked and what model device you were using as maybe these issues are even device specific. Either way compiling a list of items that these worked on certainly wouldn’t hurt for those suffering with these issues in the future.


One thought on “Logitech Unifying Receiver: Interference Troubleshooting”

  1. While it may be easy to solve once you’ve found the source of the interference, products should not be designed to fail so easily. I am completely disappointed with the Logitech M510. The LX8 had no issues whatsoever… this new model is junk.
