Last summer, IUN joined the wireless revolution by installing wireless Internet service for common areas of campus.

The following is a list of areas served by IUN’s wireless service.

Please note that there are some other areas on campus and in buildings that you may be able to access service at, however it is not guaranteed.

To access the service, simply turn on your laptop and configure your wireless card to connect to the available wireless network.

The following is a list of all the possible networks that you may connect to.

 IUN Wireless FAQ:

LOGON STATUS: http://1.1.1.1

AUTHORIZED USERS:
1. IUN students, faculty, and staff
A valid network username/password in the “User Login” or VPN pptp client enables full Internet access.
2. Authorized guest
Please call ext. 4357 or visit IUN’s technical help desk in Raintree 204 for a temporary full Internet wireless access account. (Requires department administrator approval)
3. Visitor/Guest
Logon as a guest and view http://www.iun.edu web pages only.

4. Visiting IU students, faculty, and staff-connect to a remote IU VPN server.

Wireless Technology and Performance:
1. IUN employs 802.11b (11M) and 802.11g (52M) combination wireless access points

Items that effect performance and reduce bandwidth include:
- User quantity

- Distance between wireless device and the wireless access point.
- Various physical obstructions; trees, reflective material, etc.
- Mixed 802.11b and 802.11g wireless devices
- High bandwidth applications
Q. What is a 5 minute linger?

A. If the wireless device powers down or leaves the IUN wireless network longer than 5 minutes, the user must logon or VPN again.

TROUBLESHOOTING AND HELP
1. Reboot
2. Visit http://kb.iu.edu and search for “wireless”
3. Call ext.4357 or visit Raintree 204

SECURITY

IUN attempts to balance wireless security and speed. The wireless user may choose "Maximum security / 20% reduced speed" or "Reduced security / maximum speed"

VPN 42.0.0.1 : MAXIMUM SECURITY, 20% REDUCED SPEED, FULL INTERNET

1. Method: Open a VPN pptp client session to IP address 42.0.0.1 (see operating system help files for VPN client setup information)
2. Advantages: All data packets are encrypted regardless of the web application’s ability to encrypt.
3. Disadvantages: The VPN encryption reduces bandwidth speed. Roaming is not available. New wireless users must educate themselves about VPN technology.

USER LOGIN: REDUCED SECURITY, MAXIMUM SPEED, FULL INTERNET

1. Method: Use the wireless “User Login” webpage with a valid network username and password
2. Advantages: Fastest load times. Roaming enabled. Security rests with the application’s encryption; https, SSL, secure shell, secure ftp. Secured IU applications include ONESTART, web Outlook, and many others.
3. Disadvantages: Hackers may snoop the wireless airwaves and capture information. If the web application is not properly secured (e.g., https), important information could be compromised. On the other hand, if the web application is properly secured (e.g., https), compromises are highly unlikely.

SECURITY NOTE: Wireless technology and hacker abilities are constantly improving and changing. For the best security, always choose VPN. On the other hand, IUN desires to make wireless networking accessible. If you are a new IUN wireless user, logon with “User Login”. As you become more knowledgeable about wireless and security, switch to VPN.

PDA (Personal Digital Assistants)

With a Pocket PC 2002 device at IU, why can't I browse the Web using the Pocket Internet Explorer and the Pocket VPN client?

(From http://kb.iu.edu)
Due to a design flaw, Pocket Internet Explorer will not work with VPN connections when trying to view Web pages. The problem is that Pocket Internet Explorer will only use the VPN connection when making HTTP requests within the VPN server's own domain, which at Indiana University is indiana.edu or iupui.edu. When requesting a Web page outside the VPN server's domain (i.e., outside of indiana.edu or iupui.edu), Pocket Internet Explorer tries to bypass the VPN connection, causing the request to fail. Other network troubleshooting resources also indicate that the Pocket PC VPN client was designed to work only with a Microsoft VPN server.

Currently, you have to install a third-party browser such as NetFront or ThunderHawk to browse the Web while using a VPN connection.
