If your wifi lags badly, including your Logitech Unifying wireless mouse and keyboard, this is because there is a channel conflict between these wireless devices. There is a possibility that your neighbor’s router share the same channel with your mouse. The only way to find out and resolve this ‘lag’ is to find out which channel within your work radius is occupied and which is not.

There are a multitude of problems that could be impacting the Wi-Fi and some basic network health questions you have to answer:
- Which rooms have good Wi-Fi coverage, and which don’t?
- Am I on the best channel for good coverage?
- What other devices are transmitting in my environment, and are they interfering?
These questions are not always simple to answer. Since Wi-Fi is invisible, it’s not so easy to check and see if your fix ended up working. What if you could easily answer these questions in under a minute using software that explained the hard numbers in an easy-to-understand way?
