Configure WEP
It is recommended to enable encryption on your wireless router before your wireless network adapters. Please establish wireless connectivity before
enabling encryption. Your wireless signal may degrade when enabling encryption due to the added overhead.
1. Log into the web-based configuration by opening a web browser and entering the IP address of
the router (192.168.0.1).
Click on
Wireless Settings
on the left side.
2. Next to
Security Mode
, select
WEP
.
3. Next to
WEP
Key 1
, enter a WEP key that you create. Make sure you enter this key exactly on all your
wireless devices. You may enter up to 4 different keys.
4. Click
Save Settings
to save your settings. If you are configuring the router with a wireless adapter,
you will lose connectivity until you enable WEP on your adapter and enter the same WEP key as
you did on the router.

Section 4 - Security
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm
and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with. WPA2 is based on 802.11i and
uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP regulates access
to a wireless network based on a computer’s hardware-specific MAC address, which is relatively simple to be sniffed out and stolen.
EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63
characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or
access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public key encryption
system to ensure that only authorized network users can access the network.
