Protecting your Wireless Networks

Wireless networks are less secure than cable ones. When you try to connect to your network you will be able to see all the other networks from your street.

Likewise, others will be able to see your network and, if it is not locked and secure other people would be able to use your Internet connection for playing games and downloading files. Some Internet sites have lists of ‘hot spots’ where there are unsecured networks in homes and offices, where you can get free Internet access.

The most important thing is to change the default password on the router. Most of them come with ‘admin’ as the default one. It is then easy for anyone to connect to it and change the settings.

You should also set up some form of encryption which scrambles the data on your network and only official computers with the correct encryption key can read it.The commonest type is WEP (Wired Equivalent Protection), which uses 64- or 128- bit encryption, but the more secure WAP-PSK (Wireless Application Protocol – Pre-Shared Key) and WAP2 are becoming more widely used.
