Hybrid Work Recommendations - Your Network Access

Your VPN Usage

As a staff member, I need direction on the proper usage of the VPN so that I can protect my data.

When working remotely, many of the resources and tools to complete your daily work do not require the use of the CU's VPN. A few that do include the following:

Note: Some countries outside the United States filter internet traffic. As a result, access to some CU resources (including VPN) may be restricted. Such restrictions are outside of CU's control and can change frequently. OIT is unable to know which resources may not be accessed from countries outside the United States.

You Campus Wireless Options

Service Available For Features and When To Use It Does a user need to connect to the VPN when using this service?

UCB Wireless

All CU Boulder affiliates with an active IdentiKey

UCB Wireless provides access to the network in approximately 90% of all indoor building space on campus and is the network that faculty, staff, and students should use, unless they are visiting an eduroam institution.

To gain access to a privileged system a user may need to use a VPN to access those resources.  Most daily work does not need a VPN to work (mail, calendar, Canvas, Teams, Zoom, etc.). A user may wish to protect their data in flight with a VPN since UCB Wireless is considered an unsecure network meaning unencrypted traffic is viewable by computers on the same wireless channel.

eduroam Secure Wireless

Visitors from participating eduroam institutions or for CU Boulder affiliates who are visiting other eduroam institutions.

A federated wireless network service available on the CU Boulder campus as well as hundreds of other institutions in the United States and worldwide.

To gain access to a privileged system a user may need to use a VPN to access those resources. Since this network is considered secured a VPN is not needed to protect their traffic in flight. 

Guest Wireless

Any guest visiting the CU Boulder campus.

Wireless access for CU Boulder visitors that doesn't require an IdentiKey. Connections last for 24 hours.

All employees with an IdentiKey should avoid using this network since it is for visitors and only allows certain protocols.

Remote Network Connectivity Guidance

Use this guidance to improve home internet connectivity. OIT also has a Home Networking 101 presentation available for download that goes through our recommendations, as well as a recording of the Networking 101 webinar.

Internet Speed Information & Recommendations

Whether you have applied for a federal grant for technology through the CARES Act and are looking for information on how to spend that money appropriately, or you just want to make sure your Internet Service Provider’s (ISP) connectivity meets the minimum standard for remote learning success, these recommendations can help point you in the right direction.

Most Common Types of Internet Connectivity offered in the United States: 

Broadband connections are run over a cable infrastructure, i.e. Coaxial Cable, Optical Fiber, and/or Ethernet.

  • Cable connectivity offered by Comcast/Century Link are very common and offer technical help in setting up the connection. 
  • Speeds range from 25Mbps to 150Mbps for download and 1Mbps to 25Mbps for upload. Generally, this type of connectivity is considered optimal, since speeds of over 25Mbps can offer multiple people in a single residence better than good performance. 

Cellular connections are run over a wireless “cell” infrastructure and are provided by companies like AT&T, T-Mobile, and Verizon.

  • Speeds can range depending on the service you are connected to. These services are upgraded in an evolution, as carriers roll out better speeds over time. The most common is 4G LTE and in some metropolitan areas 5G is being adopted, though speeds are limited to your device’s cellular chipset. 
  • Speeds range from 5Mbps to 12Mbps for download and 2Mbps to 5Mbps for uploads, but will vary depending on congestion and signal to the nearest cellular tower. 
  • Connecting a wireless enabled computer to a cellular device (e.g. phone or hotspot) is typically done by creating a wireless network and then connecting that device to the shared SSID or wireless network name. 
  • OIT does not recommend that these types of connections be shared between more than one user at a time. 

Base Recommendations for your Internet Service Provider (ISP) of choice: 

  • Because Zoom is the remote learning collaboration tool you will use that is most reliant on consistent internet connection, your ISP’s speed should match Zoom’s minimum bandwidth requirements. Zoom's System Requirements include at least a 3Mbps connection to take advantage of basic and advanced features.
  • Test your ISP's connection using CU Boulder's speed test site. Make sure to close extra tabs in your browser and quit any unnecessary applications before you click the Start button to begin the speed test. Be sure to test from the computer you plan on using for schoolwork and make sure it is connected to Wi-Fi or a hotspot. Any result in the download gauge showing speeds near or above 3Mbps should be acceptable. 
  • Connectivity doesn’t meet the threshold? Contact your ISP and talk with them about what internet options are available. Most broadband companies have offered increased speeds and plans that are more reasonable to meet the demand remote learning and working during the COVID-19 pandemic.
