Step 4 - Secure Your Wireless Network
If you did not buy your router used, then chances are it comes with several different security settings. If your wireless network card is new as well, then we can just use the best settings and go for it.
Using your setup software, or going under the Security section of the configuration via your browser, choose WPA2 for your security.
Your wireless router may have two WPA2 settings. If so, choose the PSK setting or the one that does not require a RADIUS server. Your router may then ask whether to use TKIP or AES (sometimes shown as CCMP) or AUTO. If it has an AUTO setting, take it. Otherwise, start with AES. (If you are interested in the why of these settings, read here.)
The PSK setting means that you need to pick a passkey for your security. This is very important!! If you do not set a passkey, someone sitting outside in their car, tablet at the ready, will be able to access your wireless network and make use of your internet service.
This passkey will also have to be entered on each device in your wireless network. It is case sensetive and can contain numbers and symbols.
Remember that your entire wireless security depends on this one passkey, so don't be shy about typing something difficult! Make it long, use at least two capital letters, at least one number, and at least one symbol.
To make a strong password use a random generator, or make a sentence that makes sense to you. Something like the following makes a hard enough password that it will be difficult to break the key, yet it will be easy for you to remember.
Don't forget to jot down your settings in your notebook or on the worksheet if you are using it.
Your wireless router may offer additional security via something called MAC Address restriction. Don't bother. Anyone who knows how to hack a wireless network knows how to spoof a MAC address, and this setting may make it hard for you to detect errors down the line.
If you get asked whether or not to turn on remote management, choose no for now.
