This article shows you how to configure the wireless security feature on a Linksys router to enable wireless encryption. This article is designed for students in CCNA, network engineers, and anyone looking to encrypt wireless communications with the Linksys wireless router. This article is part of the CCNA curriculum objective “Explain and select the appropriate administrative tasks required for a WLAN.”
Linksys router setup
The first thing to do at the time of the Linksys wireless network installation is the placement of the intelligent router according to the area to be covered. However, it is not unusual for the area covered, is in fact largely higher than desired, in which case it is possible to reduce the power of the access point router to adapt its supply to the area to cover. However, the most effective solution is to enable encryption between the Linksys router setup and the computers / network devices. To avoid problems of confidentiality of trade to the wireless network, 802.11 standard includes a simple mechanism for encoding data, WEP (Wired Equivalent Privacy are).
Wireless networks can connect to the Internet, share files and play with ease. However, its disadvantage is that your wireless activity can be captured by anyone connected to your wireless network. Therefore, critical information such as email passwords and credit card information can be stolen easily. To avoid this problem, the Linksys router allows you to encrypt their communications network in your wireless network. To do this, you have four security mode:
- WPA mixed.
The safest way is WPA2. Read the following instructions to encrypt wireless communications in the network:
Step 1: Open your favorite web browser application and enter the IP address 192.168.1. 1 in the address field. Then press Enter.
Step 2: In the authentication dialog box, type the administrator username and password. The defaults are admin / admin as username / password.
However, on some platforms Linksys router, the default value for the user name is blank and the password is admin.
Step 3: Open the Wireless tab.
Step 4: Click Wireless Security.
Step 5: In the Security Mode drop-down list, select either WEP or WPA-Personal or WPA2-Personal or WPA2 mixed. Otherwise, select Disable.
Step 6: If WEP mode is selected, then select the drive that the key to use, select a level of WEP encryption, and enter either a passphrase or 4 buttons in the appropriate text boxes. Otherwise, enter the encryption password in the Password text box and the amount of time the router is expected to renew the keys in the Group box text key renewal.
Step 7: Click Save Settings.
