2 Wireless Routers·What should I do to secure my Linksys (or other) wireless network?
·How do I ensure compatibility of WEP keys between products?
·What firmware is my wireless router compatible with?
| | | A. Following the following recommendations you can be reasonably sure that your wireless network will be safe and secure from "War Drivers" and casual hackers.
1. Change your SSID and your default password on your Access Point.
2. Setup MAC Filtering and ALLOW only the MAC addresses of devices on your network owned by you.
3. Shut off SSID Broadcasting so as to not advertise your wireless network's existence.
4. Use the highest level of WEP encryption you are allowed by your Access Point and client devices. Note that on Linksys AP's you can choose 256-bit WEP, however client products only support upto 128-bit.
5. Change your WEP keys often and do not use the passphrase generator, use any of the random number generators freely available on the web and convert the decimal number to hex.

If you do use a pass phrase, and it does work for you, then it is entirely possible for someone to hack your WEP key, with a dictionary attack, or even just by guessing.
The best WEP, known as a “Strong WEP Key”, key is a randomly generated 128-bit (or 64-bit if you must) key. However, coming up with a completely random set of 16 acceptable characters (0-9 A-F) is, next to, impossible.
To generate a STRONG WEP key, you can use the generator located at:

If you are concerned about using this web-based generator, never fear…There is a downloadable application available at:

Some experts, recommend changing your WEP keys weekly. With one of the these applications making it so easy to generate strong WEP keys, you now have no excuse not to follow that advise.
