Data Services - Using the Network in your Residence Hall

Your campus residence is equipped with high speed internet access. Most rooms have one data wall jack per room.


Connecting Using the Wall Port

Wired networking is the fastest internet you will experience at CUA. All residence halls have a network wall port.

Many computers have an Ethernet network port built into the computer. The network port is located on the back of desktop machines and on the back or on the side of notebook computers. If your computer does not have a network port, you can purchase one at most retail stores or online. An example of what you can purchase can be found here:

You will also need an Ethernet patch cable. Look for patch cables of type CAT5e or CAT6; either will work fine in your residence hall room.

Follow these steps to connect your computer to the network wall port.

  1. Turn off the computer.
  2. Locate the network wall port in your room. This diagram may help.
  3. Insert one end of the network cable into the Ethernet port on your computer.
    It does not matter which end you use; they are both the same.
  4. Insert the other end of the network cable into the network wall port.
  5. Turn on the computer and log on.

Connecting the Computer Wirelessly

All student residence halls have wireless networking available.

Nearly all notebook computers and some desktop computers like Apple iMac have wireless networking built in. If your computer doesn't have built in wireless, you can add it by purchasing a USB Wireless-N network adapter.

Windows 7

If your notebook computer has a switch or a software setting to turn the wireless radio on and off, be sure that it is turned on. Or, make sure your USB adapter is plugged in and working.

Click the Start button and select Control Panel. When viewing by category, select Network and Internet and then Connect to a network.

In the resulting window showing which wireless connections are available, select CUA-ResNet. Leave the Connect automatically setting checked if you want your computer to connect to this network automatically when it is available. Click Connect.

Mac OS X 10.6 Snow Leopard

Make sure your computer's Airport is turned on.

Then, choose Apple menu, System Preferences, and then click Network.

Select Airport in the list of network connection services.  Choose CUA-ResNet from the Network Name menu.


The name (SSID) of the CUA wireless network in ResNet is "CUA-ResNet". There are no other university-provided wireless networks in ResNet, so be sure you connect to this specific SSID only from within your residence hall.


Additional Information

Where can I learn more about how to protect my computer from viruses and spyware?

To better protect your computer, please make sure you are following the steps listed in "Safe Computing Practices".

The three most important steps are:

  1. Use up-to-date antivirus software on your computer.
  2. Use a software firewall on your computer.
  3. Configure your computer to download and install updates automatically.

I have an Apple Mac. Do I still need to run antivirus software?

Yes, we require that all PCs and Macs in residence halls run antivirus software. 

Can I attach my network enabled video game console to the network?

Yes, network enabled video game consoles such as the Sony PlayStation, Microsoft Xbox or Nintendo Wii may be attached to the campus network.

Can I attach my digital video recorder to the network?

Yes, a digital video recorder such as a TiVo may be attached to the campus network.

Can I attach my wireless printer to the network?

No, the wireless networking in the residence halls is designed to provide enhanced protection for computers. This protection prevents your computer from communicating with wireless printers. You should instead connect to your printer using a USB cable.

Do I have to set my computer to obtain an IP address automatically?

Yes. The IP addresses available to Residence Hall rooms are shared among all ResNet residents. In order for the addresses to be shared fairly, everyone must use these same settings. If you do not use this setting, your connection may be disabled until you fix your settings.

Can I use my own network equipment in my room?

No. Only university-owned network equipment may be attached to the campus network, including ResNet, since such equipment can interfere with the normal operation of the network. This means that you may not attach your own routers; managed switches; hardware firewalls; wireless access points, including Apple AIrport; storage devices such as Apple Time Capsule or Western Digital My World Book; or other network equipment.

However, you can use an unmanaged switch so that your TV, game console, computer and/or DVR can share a wired connection. Here are some that we recommend:

Model Number
D-Link DGS-105 5-Port Gigabit Ethernet Switch
5-Port Gigabit Ethernet Switch
5-Port Gigabit Ethernet Switch
5-Port Gigabit Ethernet Switch

Do not purchase a network device with wireless!

Is there other equipment or software that I can't use on the ResNet network?

Yes, the use of Sling Media's Slingbox is not permitted due to its bandwidth requirements. Use of remote access software is not permitted for security reasons.

Can I run my own server in my room?

No. Your computer or other network device must not offer any network services designed to be accessed by others on the network. This includes Internet services such as dns (e.g., named), dhcp, bootp, wins, smtp, pop, imap, http/https (web), nntp, ftp, smb, nfs, telnet.
