If you are not getting the wireless Internet signal in parts of your home it can mean that it's crashing with other wireless networks. You can try changing the channel on your wireless network. Go to point 4 of the guide Slow and unstable wireless Internet.
Did that not help? Then perhaps you need a new access point that extends the range of your wireless network. We don't provide that, but try your local electronics shop; they'll probably be able to help.
Still having trouble? Please contact our customer service centre and we will help you with the issue.
