wireless networking.

The UNO office of Information Technology Services (ITS), in partnership with departments and colleges across the UNO campus, provides wireless network access to people on the UNO campus based on common 802.11 standards of wireless networking. If you need to print to any print solution printers in the computer labs on campus, you can obtain printer drivers for your laptop or non-lab computer.

where is it?

Most of the buildings on the UNO campus have 100% wireless coverage. With the exception of student housing, all buildings on the UNO campus have some percentage of UNO-provided wireless access. The seating areas along the primary walkway through the center of the UNO North campus also have UNO-provided wireless access. For a complete overview of wireless coverage for the UNO campus, see the UNO campus wireless coverage map

how can I start using it?

First you need a computer or other portable device with 802.11 wireless networking capability either built in or with a wireless network card installed. If you do not have or are not sure if your computer or device has 802.11 wireless networking capabilities, check with the company or person from whom you obtained the item. Then it is normally just a matter of being inside an active UNO wireless area. The UNO campus wireless network has an SSID network name of 'tsunami'. The UNO wireless network will attempt to automatically assign the computer or device a network number using DHCP. You may need to turn the computer or device off and back on so it seeks a network number. If your computer or device does not have a fairly current version of a standard Windows or Mac operating system, there may be some special steps that system requires you to perform before being able to use wireless networking with that device. Check the website or call the technical support number for the device if you’re not sure.

is it reliable?

How reliable your 802.11 wireless network connection will be depends on many physical factors including type of walls, floors, windows and furniture the signal is passing through. The campus wireless network coverage map (see the ‘where is it’ section), indicates general areas where the wireless signal is strong enough that 98% of the time a good, reliable connection will be available. Note that USB wireless adapters for computers typically have very bad wireless performance and are not recommended.

is it secure?

The UNO campus wireless network by default uses unencrypted wireless communications. That means someone in the same wireless area could monitor some of your wireless communications. WEP and similar encryption is not used because it requires clients to know the encryption key. Doing so would discourage use of the wireless network. Most UNO web based services automatically encrypt your connections every time you log in, no matter where you log in from. Look for a small padlock symbol at the bottom of your web browser to tell if your communications with that system/service are encrypted. ITS is working to implement a wireless encryption system that will allow wireless network users to activate wireless encryption on demand. Watch for possible updates on this project in early 2007.

what services (ports) are available?

The UNO campus wireless network has a firewall to reduce instances of malicious activity. This allows students, faculty, staff and visitors to use the wireless network without having to request access or use special software. The UNO campus wireless network and firewall allow standard and secured Internet web browsing as well as the following service ports and related service names.
