This article details various troubleshooting methods to try when having difficulty getting connected to the internet on campus.
Wireless Networks (Wi-Fi)
If you are unable to connect to wi-fi networks on campus, please try each applicable troubleshooting method below:
Check the Guide
For some devices, getting connected to UVM WiFi can be more complex than others. A good first step when troubleshooting your WiFi connection is to review our guide on Connecting to UVM Wireless.
Remove and Re-add
Check your System Time
Some devices will be unable to connect to a WiFi network if the system clock doesn’t match the servers’ clock.
Instructions are different for Windows and macOS users:
- macOS – If the date or time is wrong on your Mac (apple.com)
- Windows – How to set your time and time zone (microsoft.com)
Review your System's Age
Older macOS or Windows operating systems may be unable to connect to UVM’s network.
Computers running an older operating systems may be less secure, as developers no longer release security patches and other updates for these systems.
It’s important to keep your operating system updated. You can check if your system is outdated using these guides:
macOS - Remove your outdate Profile
macOS computers store information relating to network authentication in items called profiles. Occasionally, an outdated profile will prevent a proper network connection from being made.
Check your Network Adapter
If you don’t see the UVM Wireless network in some places on campus, but you have no trouble connecting in others, it’s possible your network adapter is unable to connect to the 5GHz band.
UVM is steadily moving to only broadcasting the 5GHz band, as this improves network speed. When necessary, our Network Services team can enable the older 2.4GHz band.
Please contact the UVM Tech Team, and include the specific location where you have difficulty connecting.
Windows users can open PowerShell and run the following command to check that their compatibility with the 5GHz band. If 802.11ac is listed, your adapter should support a 5GHz connection.
netsh wlan show drivers | Select-String "radio types supported"
macOS users can open Terminal and run the following command to check that their compatibility with the 5GHz band. If ac is listed, your adapter should support a 5GHz connection.

Wired Networks (Ethernet)
Most devices in most buildings on campus will need to be registered before connecting to the campus wired network.
When connecting a computer to the wired network via ethernet, there are several physical places where the connection can be broken.
- The computer and its ports
- The ethernet cable and any adapters used
- The wall-mounted ethernet ports
If possible, test each of a second device, a second cable, and a different port. If there is a hardware problem preventing the connection, this will often help to locate it.
If the wall ports are visibly broken, please submit a service request to have them inspected:
If you are not in a residence hall and the port does not appear to be visibly broken, please contact Network Services.
If it is determined that there is a problem with the ethernet cable or adapter that you are using, you can buy a new one at the UVM Bookstore.
