Wireless Internet Access

Free access to the Central Rappahannock Regional Library's Internet network is provided in all public areas in the CRRL headquarters and all branches using your own wireless-enabled laptop computer or personal digital assistant (PDA).When you launch your Web browser, your computer's home page will appear and you may begin surfing immediately.

Getting started:

You will need a Wi-Fi-compliant 802.11b/g wireless Ethernet device installed in your laptop or PDA. Set your wireless network adapter's Network Identifier (also known as SSID or Network Name) to CRRL (case sensitive).

General Information:

What is Wi-Fi?
Wi-Fi enables a person with a wireless-enabled computer or personal digital assistant (PDA) to connect to the Internet when in proximity of an access point.

How can I make my equipment wireless enabled?
Many new laptops and PDAs come with Wi-Fi as a standard feature. Older devices can be outfitted with an 802.11b or 802.11g wireless network interface (NIC) card at local electronics and computer stores or by purchasing online. Consult your manual for specifications.

Guidelines for Using Wi-Fi at CRRL:

Who Can Use Wi-Fi?
Anyone who complies with the library's internet use policy may use our wireless access service. For the library's policies and information on appropriate Internet access from CRRL sites, please see "Use of Computer Resources Policy," online at

Do I need a library card?
A library card is not required.

Are there any additional guidelines?
Patrons are encouraged to use headphones when listening to audio files. As in any public place, patrons should safeguard personal belongings. Cords plugged into a patron's laptop should not block any library walkway or access to resources and materials.

Is the information on my laptop safe from hackers while I am connected?
The Library's wireless network is not secure. Information sent from or to your laptop can be captured by anyone else with a wireless device and the appropriate software, within three hundred feet. Using virus protection, a personal firewall, and other measures to protect the information on your laptop is highly recommended, and is the sole responsibility of the user. The Library is not responsible for any loss of information or damage to your equipment that might result from using the wireless network or other facilities of the library.

If I change my computer configuration to work at the library, will it still work at my home or other Wi-Fi locations?
Yes. If you changed your laptop's network configuration to make it work in the library, remember to change it back when you are at home, work, or other Wi-Fi location.
