9-Check Your PC Activity
This tip refers explicitly to PCs and not any other devices around your home connected to your Wi-Fi network. If your PC seems sluggish but other networked devices are performing fine, it may be that there are too many programs open and running in the background.
These programs will compete for access to your computer’s RAM and processing power. The result is that your PC’s overall performance will slow. To rectify these issues, go into the Task Manager, and check which programs are running. If you notice anything you are not using, close it down to free up resources and speed up your PC’s performance.
