Frequently Asked Questions - Networking

1. How do I register my device for Internet access?

Device registrations must be performed while connected to Concordia's network. It will not work from the Internet. If your device has a web browser, follow the steps below. If your device does not have a web browser (e.g., a gaming console or a Blu-Ray player), follow the steps for no web browser.

Web Browser

  1. Connect the device to the network
  2. Open a web browser and visit www.cune.org
  3. Click the link to Manage Account and login
  4. Click the link to Register your device
  5. Click the button to Register

No Web Browser

  1. Connect the device to the network and turn it on
  2. From a computer with a web browser, visit www.cune.org
  3. Click the link to Manage Account and login
  4. Click the link to Register your device
  5. Enter the MAC address of the device
  6. Click the button to Register

A MAC address is also known as the Wi-Fi address, physical address, hardware address, LAN address, adaptor address or Ethernet address. It consists of 6 pairs of digits, usually separated by a colon, a dash or a space. A digit may have the value of 0 to 9 or A to F (case does not matter). For example,

00 12 34 56 AB CD
00-12-34-56-AB-CD
00:12:34:56:ab:cd
00123456abcd

To find a MAC address, check the network configuration settings on the device. In rare cases, the MAC address is printed on a sticker on the device or on the box it came in. To find directions online for locating the MAC address of your device, search for a phrase like "find mac address xbox", but use your kind of device in place of Xbox. Note that if your device has both a wired and a wireless adaptor (common for a laptop), each connection has a different MAC address. Consequently, each connection must be registered separately, if you wish to use both connections (but do not use both at the same time or your device may exhibit unreliable connection issues).

Do not enter an O "oh" for a zero, and be careful not to confuse a B with an 8. They can be difficult to distinguish. If you enter an incorrect MAC address, the device will not be detected on the network.


2. Will all devices work on the network?

Most devices will function normally on Concordia's network, but due to security features and other issues, some devices might not work as expected. A device, such as a printer, for example, will not work when connected directly to Concordia's network. To print a document, your computer must contact your printer. That is not possible, because personal devices are not permitted to communicate with each other over the network.

The best solution is to connect your computer directly to your device with a cable, if possible. You might also be able to contact your device with infrared or a Bluetooth connection. Consult the device manual for options.


3. How do I configure my computer for wireless network access?

Note: After establishing a wireless connection to Concordia's CUNE or CUNESecure network, students must register their connection at www.cune.org in order to access the wireless network, even if you have already registered the wired connection.

An encrypted or unencrypted wireless connection is possible. Users are strongly urged to configure their computers to use an encrypted wireless connection for secure communication.

  17. Click "Continue"
  18. Your computer should then make a secure connection to CUNESecure

Now, register your computer at www.cune.org

G. Generic information for an encrypted connection

If step-by-step instructions are not available for your computer, use the following information to configure your computer for an encrypted wireless connection. The terms below vary slightly from one software package to another. For example, one program might have an option labeled MSCHAPV2, and another program might call it EAP-MSCHAP-V2. However, it will be close enough for you to easily recognize.

Description Value
Authentication procedure 802.1x authentication should be checked
Wireless network name (SSID) CUNESecure
Network authentication WPA2 or WPA2 Enterprise
(not WEP, WPA, WPA2 Personal or WPA2-PSK)
Data encryption AES
Authentication type PEAP (Protected EAP)
Authentication protocol MS-CHAP-V2
Validate server certificate Should be selected
Certificate issuer Choose "Any valid certificate", if available
Server or certificate name If multiple names are allowed, enter both servers
vradius1.cune.edu
vradius2.cune.edu
Otherwise, enter cune.edu and choose the option to match the domain.
Login name concordia
Password concordia (all lowercase)
Domain Leave blank
Roaming identity User your email username (e.g., John.Smith)

After making a successful connection, register your computer at www.cune.org

H. Making an unencrypted wireless connection

Older wireless hardware might not be able to provide WPA2 Enterprise encryption. In that situation, the only choice is an unencrypted wireless connection.

If you visit a secure website that starts with "https", the information between the website and the web browser will be encrypted, whether you are using an encrypted wireless connection or not. The web browser will display a small lock or other symbol to indicate that the information is secure. Such secure websites include banks, credit card companies and shopping sites. You should consider connecting your computer to the wired network during the times you visit unsecure sites where you enter personal information.

To make an unencrypted wireless connection using the software included with Windows XP, follow these steps.

  1. Go to Start
  2. Click on Connect To
  3. Click on Show all connections
  4. Right-click on Wireless Network Connection
  5. Select View Available Wireless Networks
  6. Click the CUNE network
  7. Click the Connect button
  8. Close the windows
  9. Register your computer at www.cune.org

If you use third-party software or a different operating system, use the steps above as a general guide for making an unencrypted wireless connection.


4. Where may I access the wireless network?

At the time this is written, wireless access is available in student areas of Janzow Campus Center, Jesse Hall, Science Building, TLEC, Link Library, Walz, Klebenes Court in Music, the stairway landing in Brommer, the Lincoln campus (Fallbrook) and in the dorms.


5. May I use my own wireless LAN?

Student wireless LANs are not permitted. Concordia University reserves the wireless LAN radio spectrum and other radio frequencies on campus property for its own purposes. Student wireless LANs would with Concordia's wireless network as well as change the network topology and potentially compromise the security of the network. From a practical point of view, wireless LANs are convenient but generally have slower and less reliable performance than the wired network. A wireless LAN is shared with all neighboring devices, but a wired connection is dedicated to you.


6. What if my network connection is not working?

First, read all of the questions and answers in the Networking section of this document.  Most problems can be resolved by using the information found here.  The majority of reported problems are the result of using the wrong patch cable or a bad patch cable.  Do not use a telephone extension cable for a patch cable as it does not work, and it may damage the pins in the connectors.  See the question, "What does my computer need for the network?" for details.

A. If this is the first time you have connected your computer to the network and you cannot reach www.cune.org, this may be a web browser or a cable problem. For the web browser, see the question, "Why doesn't my web browser display any web sites?" To test the cable,

  1. try plugging your patch cable into another network outlet in your room
  2. borrow a known working cable from your roommate or someone on your floor
  3. have your roommate or someone on your floor use your network cable
  4. have your roommate or someone on your floor plug their computer into your network outlet

If the problem stays with the network outlet, report the problem to Computing Services. If the problem follows your network cable, replace the cable. If the problem follows your computer

  1. check that your Ethernet adapter has been properly installed
  2. check that the appropriate drivers have been installed for the Ethernet adapter (installation is usually automatic with the latest versions of Windows and MacOS)
  3. check the network and web browser settings on your computer as described in this document

B. If your computer was working but now you cannot reach any web sites, including www.cune.org, the problem may be related to software that you recently installed (particularly game software). Windows XP allows you to "back up" to the point before you installed the software (search help for "System Restore"). You may want to try that option, if available. You may also want to use the "repair" or "restore" CD, if one came with your computer.

C. If you can reach both web sites www.cune.org and www.cune.edu but not other sites on the Internet, your computer may have used all of its Internet allowance. To check your Internet usage, visit www.cune.org from your computer and click the link for Internet Usage.

D. If you can only reach www.cune.org, your computer might not be registered for network access. Visit www.cune.org, click the link for Manage Account, login and register your computer.


7. What does my computer need for the network?

Most desktop and laptop computers today include networking capability. Your computer may already have everything you need. To function on Concordia's network, your computer must have two things, 1) a 10/100 Ethernet adapter (card) with an RJ45 jack and 2) a patch cable (also called a straight through Cat5 cable or an unshielded twisted pair (UTP) cable) with RJ45 connectors. One end of the patch cable plugs into the Ethernet adapter in your computer, and the other end plugs into the network jack in your room.

Cards and cables are available at places like Radio Shack and Best Buy. A modem will not work on the network. A modem is for a telephone line and a dial-up connection. The computer must have an Ethernet adaptor or a combination Ethernet/modem card (typically used with laptops).

An RJ45 connector looks like a large telephone connector, but do not use a telephone extension cable for a patch cable as it does not work, and it may damage the pins in the RJ45 jack.

(Click for a larger picture)

To check if you have the proper cable, hold both ends of the cable side by side with the plastic clip away from you and the cable at the bottom of the connector. You will see gold pins at the top of the connector and colored wires through the plastic window. The wires should be in the same order from left to right in both connectors. The order of the wires should match either scheme A or scheme B. If the wires in both connectors do not match the same scheme, you do not have the correct patch cable.

Scheme A

Scheme B


8. How do I configure my computer for wired network access?

Almost all desktop and laptop computers today are already configured to work on Concordia's network without any changes. Simply connect your patch cable to the Ethernet adaptor on your computer and to the network wall jack in your room. Then, visit www.cune.org to register your computer for full network access. Until your computer is registered, it will only have minimal network access.

9. How do I find my computer's MAC address?

Your computer uses an Ethernet adaptor or card to communicate on the network. Every Ethernet adaptor is assigned a numeric ID by the manufacturer that is similar to a serial number. The ID is referred to by various names, including adaptor address, hardware address, physical address, MAC address and Ethernet address. The ID consists of 6 pairs of digits, usually separated by a character. The digits consist of the numerals 0 through 9 and the letters A through F (case does not matter). Here are example Ethernet addresses.

00:12:e5:b6:f3:31
00-12-E5-B6-F3-31
00 12 E5 B6 F3 31
0012E5B6F331

If you register your computer online, the numeric ID is automatically displayed for you. If you need to find the address by hand, follow the steps below for the operating system that you are using.

Windows XP/Vista/7

  1. Click the Start button in the taskbar and select Run.... If Run... is not present, click Start Search and enter Run.
  2. Type the word command in the Open box and click OK.
  3. When the command window opens, type ipconfig /all and press return.
  4. In the information that is displayed, look for Ethernet adapter Local Area Connection. The Description will list your Ethernet adaptor. The Physical Address will be just below that. If the Description lists "PPP adapter", the information in that section is for the modem, not the Ethernet adaptor. For the wireless adapter, look for Wireless Network Connection. The Physical Address will be listed below that.
  5. Type Exit and press return to close the window.

  4. For Mac OSX 10.5 and above, click Built-in Ethernet or Airport in the left column of the Network window. Click the Advanced button. In the drop-down, click either the Ethernet or Airport tab. The physical address is next to "Ethernet ID:" or "AirPort ID:".

iPad/iPod/iPhone

  1. Launch the Settings app.
  2. Select General in the Settings menu
  3. Select About
  4. Look for Wi-Fi Address or Wireless Address (but not Bluetooth).

10. Why doesn't my web browser display any web sites?

There are several reasons why this would happen. If you have not registered your computer for Internet access, you will not be able to reach any sites on the Internet, and you will also have limited access to Concordia's network. To solve this problem, visit www.cune.org and register your computer online by clicking Manage Account, logging in and clicking Register your device.

If you used your computer with an Internet service elsewhere, you might have manually changed the network configuration. Change the network configuration to use automatic settings.

Some anti-virus and Internet security software that you install might change your web browser to use a proxy server. You will need to find your web browser's proxy settings and turn them off or adjust the configuration of the anti-virus or security software.

If you have exceeded the maximum amount of Internet traffic you are permitted to send or receive over a period of time, you will be unable to access sites on the Internet. You will be able to access services on Concordia's network. To check your Internet usage, visit www.cune.org and click the link for Usage. See other questions in the FAQ about Internet usage.


11. Will Concordia set up my computer for me?

The Computing Services department at Concordia University does not provide installation, configuration or repair services for student computers. You will need to enlist the help of a friend or family member or contact a computer repair service about those issues. However, they will provide limited assistance with installing and configuring your network connection.

If your Ethernet adaptor is not installed or if you are not able to configure the adapter by following the directions in this document, you may schedule an appointment for the adapter to be installed and/or configured for you. The computer must boot without any problems (i.e., it must be working correctly) before an installation will be attempted. You may need the original installation disks/CDs for your Ethernet adapter and for the operating system (i.e., Windows or MacOS).

Laptops must be brought to the Computing Services department for the scheduled appointment. A Computing Services worker will visit your dorm room for desktop installations. You must be present in the dorm room during the installation. If it appears that there is a software or hardware problem with your computer, you may be referred to a computer repair service.

After the installation, the adaptor will be tested to confirm that it is configured and working correctly on the network. The configuration of software on the computer (e.g., instant messaging clients, voice chat software, word processing, etc.) is the sole responsibility of the computer user. If you have problems and tests indicate that the network connection is functioning properly, you may be referred to a computer repair service.

Please note that due to the large number of network connections made at the beginning of a semester, there may be a waiting period during the first two weeks for appointments that require a visit to the dorm room. We appreciate your patience during a very busy time.


12. Can I set up a web server or other service?

Concordia has designed a secure network that allows your computer to access academic resources on campus and on the Internet. However, malicious people and infected computers are prevented from probing and attacking your computer. The same feature that protects your computer also prevents others from directly accessing a web server or any other service on your computer. You are encouraged to use www.cune.org for personal web pages (see other questions in this FAQ for details about web pages).
