It's easy to cause WiFi problems by accidentally blocking the signal from your router, so this is the first thing you should check.
Make sure your router is as central in your home as you can get it. This is especially important if you live in a bigger place, which is more likely to have dead zones or blind spots. A central location means your router can broadcast the WiFi signal equally to more areas of your home.
The signal range of your broadband connection can also be affected by the layout of your house, certain appliances or even tiles, so it's worth making sure there are as few things covering your router as possible.
