Wireless networks make it easy to surf the internet from around the house, but every so often you may find a place where you can't connect to the network. All wireless networks have a limited range, and obstacles such as walls and furniture can block the signals, so some rooms might not get internet access - these are often known as dead spots.

Dead spots are usually easy to fix. Moving the wireless router to a location near the centre of the house often helps, but in big homes you may need to invest in a wireless repeater. This acts like a second router, spreading the signal over a wider area.

It is also worth checking for common forms of interference, such as microwave ovens and cordless telephones. If other wireless networks nearby are interfering, most routers allow you to choose a different wireless channel for your network - check the manual to see how.
