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.

Select the level of security for your wireless network:
• Best - WPA2 Authentication
• Better - WPA Authentication
• Good - WEP Encryption
• None - No security
Click
Next

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
Setup
and then click
Wireless
Settings
on the left side.
2. Next to
Security Mode
, select
WEP
.
3. Next to
WEP Key Length
, select the level of ecryption (64
or 128-bit) and either
Hex
or
ASCII
.
Hex
- (recommended) Letters A-F and numbers 0-9
are valid.
ASCII
- All numbers and letters are valid.
4. 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.
5. Next to
Authentication
, select

6. 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
