Without the WEP encryption key, unauthorized users see only garbled data and cannot read what is being sent across the network. Which is good — we like simple names that everyone knows. This table provides a quick, at-a-glance view of the four main The basics include a wireless base station an access point — AP — or wireless home router and appropriate wireless network adapters in your computers and other devices attached to the network.
This list provides an overview of all the bits and pieces you either will or might need in your network. Cheat Sheet.

University units and individuals may not disconnect a wireless access point from its associated wireless port or interfere with any components of the wireless AP assembly including antennas, antenna cables, or management cables.
Wireless ports are specially configured to supply electrical power to the wireless access point and may cause permanent damage to an improperly connected end-user device. Wireless network installations at University locations consist of the necessary Wi-Fi certified wireless access point devices. The number of access points required will be determined by initial estimates of demand for users and the size of the area to be covered.
If the number of users to be served exceeds the practical number of users that can connect to single access point with sufficient bandwidth available to each user, additional access points may be installed. In areas with a high density of users, such as classrooms and lecture halls, additional access points will be installed to satisfy the usage requirements.
How WiFi Works
In order to ensure the reliable performance of the University's network, Pitt IT will investigate reports of specific wireless devices that are suspected of causing interference and performance problems in the same manner in which Pitt IT investigates reports of specific devices connected to wired ports that are suspected of causing disruption. Although Pitt IT will not actively monitor content carried on the University's wireless network radio frequencies when investigating reports of potentially interfering devices, wireless network detection equipment will be used to detect unauthorized wireless network equipment.
Units will be required to remove any such equipment found in unit-controlled University space.
As the number of users increases, effective wireless network performance may be diminished. Current industry standards for wireless network service do not provide sufficient throughput to effectively support bandwidth-intensive applications and network services. Pitt IT will address problems encountered in the use of wireless network services according to the following priority list: public access, academic, research, administrative, and staff use.
Network access logs will be maintained containing the username, time of access, and duration of use for all users who access the network using wireless connections. This information and will be provided to authorized governmental authorities if the University is required to release such information. To provide additional security, all University wireless networks will require authentication of end users to the network upon connection of any wireless end user device using an The University's Central Directory Service will be used as the basis for authentication to services, including wireless network access.
The use of WPA and Reports have been published demonstrating the weaknesses in the WEP protocol and stating that it should not be used to protect sensitive data, such as identifiable patient information, payroll, and student data.
With the use of the newer and more advanced encryption mechanisms and user authentication protocols, these weaknesses are mitigated. Although the security of the wireless network is now as secure as the wired network, the University will prevent wireless access to these kinds of data when such data are stored on protected central services. University students, faculty, staff, and units must follow the terms of all applicable University acceptable use policies, network usage guidelines, and all applicable local, state, and federal regulations when using equipment connected to the University's network whether or not the individual is using wireless or wired network connections.
Violations of such guidelines will be reported to the University's computer incident response team and may be forwarded to the appropriate University or governmental authorities.

University students, faculty, staff, and units should be aware that the use of wireless network connections may increase the risk that confidential information can be intercepted by unauthorized or unintended parties. This risk in inherent in wireless network technology irrespective of security measures that can be implemented by the University.https://psychininul.ml

Users should avoid sending or receiving confidential or other sensitive data via wireless connections whenever possible. Some services can have a negative impact on a wireless network because they generate a high level of activity on the network. Such services can negatively affect your wireless network performance and the network performance of other wireless users. The wireless network is a shared resource, which means the bandwidth available to each user of an access point will decline as high-bandwidth services are used.

If a student, faculty member, or staff member has a need for a service that requires high bandwidth, a wired network connection should be used. The following list provides examples of high bandwidth usage. Please note that this list is not all-inclusive. You cannot use the computer you have connected to the wireless network as a server of any kind, such as:.
An unsecured computer may have problems that will also result in high bandwidth usage. The following are examples of possible problems:. Some activities may also use excessive wireless bandwidth. The following are some examples of user activities that consume high amounts of bandwidth:.
Recommended settings for Wi-Fi routers and access points
Problems can occur if other devices use the same radio frequency range 2. Because of the potential for conflicts, it is important for all users to understand which technologies are permitted in our environment and which are not permitted. In order to provide wireless network service at the highest level of quality, all non-client devices that use the 2.
Only devices that are part of the PittNet Wi-Fi network will be permitted to use the 2. But insomnia and information overload are topics for another time. WiFi: Handy but Also Harmful? Building a Wireless Network. Prev NEXT. A wireless router uses an antenna to send signals to wireless devices and a wire to send signals to the Internet. The name of the network, known as its service set identifier SSID -- The default setting is usually the manufacturer's name.
The channel that the router uses -- Most routers use channel 6 by default. If you live in an apartment and your neighbors are also using channel 6, you may experience interference. Switching to a different channel should eliminate the problem. Your router's security options -- Many routers use a standard, publicly available sign-on, so it's a good idea to set your own username and password.
AES is considered the most secure. Public hotspots are either open or use any of the available security protocols, including WEP, so use caution when connecting away from home. WiFi Protected Setup WPS , a feature that ties a hard-coded PIN to the router and makes setup easier, apparently creates a vulnerability that can be exploited by hackers, so you may want to turn off WPS if possible, or look into routers that do not have the feature. It doesn't use a password to authenticate users -- it uses a computer's physical hardware.
Each computer has its own unique MAC address. You must specify which addresses are allowed when you set up your router.
If you buy a new computer or if visitors to your home want to use your network, you'll need to add the new machines' MAC addresses to the list of approved addresses. The system isn't foolproof. A clever hacker can spoof a MAC address -- that is, copy a known MAC address to fool the network that the computer he or she is using belongs on the network.
