Before You Arrive On Campus

Here are a few tips that will make the ResNet connection process much easier and help protect your computer from viruses and spyware.

Install Updates

Download and install all available updates for your computer. Updating Instructions

Scan Your Computer

Scanning your computer for viruses and spyware then removing any you find can drastically improve you computer's performance. It may speed it up and will help protect your computer and you from malware and other unwanted programs and files on your computer. You can learn more about and download anti-spyware software on our Security Page. You can also find information on viruses at Microsoft's Security page.

OSU uses a malware detection service called FireEye on all wired/wireless networks. If your computer has a virus/malware infection that gets caught by the FireEye service, your access to internet on campus will be disabled until your computer is cleaned.

OSU provides instructions on how to install and utilize programs like Sophos and Windows Defender/Security Essentials anti-virus softwares and updates to all students.

Getting started on Campus

Once you are on campus, in order to get your devices online, you will need to register them on the network. This is done in one of two places.

OSU Wireless Network Use Policy

OSU provides network connectivity in support of the educational mission of OSU. Using the network at OSU is a privilege. As such, it is the responsibility of each individual to use these services appropriately and in accordance with all University policies and applicable laws.

Before using the OSU Wireless Network, you should read the OSU Acceptable Use Policy.

Choosing the Right Network Cable

When connecting your computer to the network, you must use a network cable (also known as an Ethernet or CAT–5/CAT-5e/CAT–6 cable). A regular phone cable will not work, even though it looks similar to a network cable.

Network cables can be purchased at the OSU Beaver Store.

Phone & Network Cable Differences

  • The jack at the end of network cables is wider than a phone's cable.
  • Network cables are usually thicker and rounder than a telephone cable.
  • Network cables usually have more pins then phone cables.
  • Network cables have larger RJ-45 connectors and phone cables usually have smaller RJ-11 connectors.

Connecting Devices

Registering Devices

It is possible to connect your internet ready game consoles to the Residential Network to play online games. Each of these devices has a hardware address that must be registered with ResNet for the device to have access to the network.

To register devices (wired):

  1. Go to to
  2. Click on 'Register a Device' under 'Self-Service' to the left
  3. Find your MAC address? for the device ('How to' table here)
  4. Put in the MAC address and Computer Name(such as:xbox, ps4, laptop, tacos), then register the device.

To register devices (wireless):

Go to the Selfreg Registration helpdoc page and follow the instructions for wireless connections.

Multiple Gaming Devices

You can connect any device with a wireless card to the wireless network in the dorms. If you have multiple gaming devices that need access to a wired port, or you want all devices to be on their own private network, you will need a properly configured router. You will also need to configure port forwarding on your router to make some online games work.

Here is a page on using routers on ResNet: ResNet Routers

Network Media Players (ROKU)

Network Media Players are devices that can stream shows from providers like Netflix and Hulu directly to your TV by connecting to the internet. Certain models have a hard-coded DNS which causes them to have connection problems on OSU networks, including ResNet.

Typically connecting through an Ethernet cable will resolve the issue, so we always recommend that people buy Media Playrs with Ethernet ports. Most players have ports already, but some like the Roku HD and Roku 2 XD do not. 

Getting a wireless router should fix the connection issue, but this has not yet been tested. If you had to choose a Roku, its highly recommended to get the Roku 2 XS, because it is currently the only member of the Roku lineup that has an Ethernet port built in.

Restarting Your Connection

Computers will sometimes lose their connection to the Internet. Some causes may be power outages or surges, problems with the University's network hardware, or improperly configured settings on other people's computers on the network. Often a computer's network settings can be "flipped off and back on" and will start working again. This process is easy to do, and fix most connection issues.

There are a few ways you can reset your computer's network connection:


1. Restart Your Computer

This is the most effective way to reset your network configuration, as every program and service will be shut down, then restarted again. Restarting will reset your network connection regardles of what operating system you have (Windows, Mac OS X, Linux).

If you are unable to shut down your computer, or you don't want to for some reason (too many things open, currently working on something), you can try option 2 or 3 below:

2. Network Diagnostics (Windows)

  1. Click the Start circle at the bottom left of your desktop and right click the Network button.
  2. Press the properties button and wait for the Network and Sharing Center screen to appear.
  3. To the right of the words Local Area Connection there will be a link titled View Status. Click it.
  4. In the box that appears, press the button labeled Diagnose.
  5. Windows will inform you that it is identifying the problem.
  6. If Windows isn't able to locate a specific problem, you will be informed as such.
  7. In the box that appears, press the button labeled Reset the network adapter "Local Area Connection"
    (Your adapter may have a different name)
    When the process is complete, you will be informed that the problem has been resolved.
    You may now try your internet connection once more. If the connection still fails, contact the ResNet Helpdesk and we will be happy to assist you with further troubleshooting.

3. Disable/Re-enable Adapter (Windows)

  1. Click Start » Control Panel
  2. Choose "Network Connections"
  3. Right-click on Local Area Connection » choose Disable
  4. Wait a few seconds then Right-click on Local Area Connection » choose Enable
  5. Right-click on Local Area Connection » choose Status » select the Support tab


The IP address? in the Status window should be 128.193.x.y, where x and y are two numbers between 0 and 255. If so, the computer is communicating with the network and you should be able to access the Internet.

If the IP address is in the form of 10.195.x.y then your computer is not registered on ResNet. If your IP address is 10.193.x.y then your system has be disabled and you should check your ONID email for additional information.

Setting up a printer in the dorms

Below you will find different ways you can hook up your printer in the dorms.

USB Connection

The easiest way to use a printer in the dorms is directly connecting the printer to your computer via a USB cable. Many computers will correctly detect the printer and automatically install the proper programs when plugged in. For printers that do not automatically do this, there will generally be a CD that comes packaged with the printer that you can run.

Wired Connection

If your printer does not have a USB connection, but has an Ethernet port on the back, you can connect your printer using a wired connection. You will need an Ethernet cable (Cat-5 or higher is recommended) to connect your printer to your router. There are two ways to setup a printer using a wired connection.

The easier method is to connect and register a router, and from there, connecting your printer and computer to your router via two of the numbered LAN slots in the router. Your printer and computer will share a private network, allowing you to use your printer.

How to Set Up a Router on ResNet

The other method is to directly connect your printer to the orange or green internet jack in your room. If you decide to do this method, you will need the computer’s Physical or MAC address?. This is a 6-part ID that identifies your printer. The address will generally look like this:

5A-6B-7C-8D-9E-0F or 5A:6B:7C:8D:9E:0F

You can usually find this address through the menu of your printer, either under Network Settings or by printing a test page.

Once you find this address, go to ResDesk. Login with your ONID credentials, click on Register a new device, fill in the MAC address and a description, accept the terms and conditions, and submit. It might take up to 15 minutes to add your device to the network.

Wireless Connection

There are two types of wireless printers: WiFi and Bluetooth.

If you have a WiFi printer, the only way to access the Internet is to set up a wireless router. However, this is not recommended, since it can conflict with the university’s wireless services.

How to Set Up a Router on ResNet

If you have a Bluetooth printer, ensure your computer has a Bluetooth adapter. This is a small device that allows your computer to recognize Bluetooth signals. The process of connecting the printer is highly automated. Windows has a wizard for installing the printer by going to Start -> Control Panel -> Hardware and Sound -> Printers -> Add a printer, while Macs have a Add Printer button under the Print menu that pops up when you try to print.

Using Wireless Routers on ResNet

ResNet provides wired network ports in every residence hall room, and most rooms are covered by the ResNet wireless network. We highly discourage the use of personal wireless routers and wireless access points as they can interfere with the OSU wireless coverage provided in all residence halls. If you have poor wireless coverage in your room, or need to connect more than one wired device, you can set up a wireless/wired router in your room.

Router Basics

A router is a network device allowing multiple computers, handheld devices and game consoles to communicate with each other and share a single connection to the Internet. They usually contain one uplink (WAN) jack and 4 Ethernet (LAN) jacks where network devices can be plugged in.

Securing Your Wireless Router

ResNet requires you to secure your wireless router to use it. You must have a password set up on your router so not just anyone can connect to it. Unfortunately, some routers ship with encryption turned off, leaving it completely exposed. Enable your router's encryption and use the strongest form supported by your computer. This will most likely be WPA2, as it is the most recent and most secure form. Only use other forms if you have a device that doesn't support WPA2.

Be sure to change the default login information to change settings to prevent others from changing your wireless settings.

How To - Secure Wireless Router Set Up

Connecting the Router

Plug one end of an Ethernet cable into the orange or green internet jack in your room, and the other into the WAN, Uplink, or Internet port of the router. Connect your computer and other devices to the LAN ports on the router.

Register the Router

To get your connection working, you'll need to find and register the routers MAC address?. This may be physically written somewhere on the router, or you may be able to find it in the router's web–based interface. Consult your router's manual for the best way to find the adapter address.

MAC address

To register the device, login to ResDesk. You will be prompted to type in the hardware address found above, agree to the acceptable use policy, and click submit. Doing so will register your device.

Once the router is registered, all network devices connected to the router will have access to the network.

Additional Help

If you are having trouble setting up your router, or are wondering if it was secured correctly, feel free to call the OSU Computer Helpdesk at 541-737-3474. We can walk you through setup over the phone.
