Wi-Fi Connection Tips

The UC San Diego Wi-Fi network is a complicated system of over 10,400 Wi-Fi access points, plus centralized wireless controllers, authentication infrastructure, IP addressing infrastructure, and more. Your phone, tablet or laptop is constantly trying to connect to an access point, even if you’re not actively using the device. The following tips may help improve your Wi-Fi experience. 

  • If you have a weak Wi-Fi connection after recently arriving at a location, turn off Wi-Fi in your device’s settings, then turn it back on. This will help you connect to the closest access point. 
  • If you’ve recently changed your Active Directory (AD) password, go to your device’s settings and “forget” the UCSD-Protected network, then reconnect with your new credentials. 
  • When placing food orders with HDH dining services, establish a strong connection then stay in one place while completing the order. Moving while ordering increases the chances of the connection being interrupted and the order not processing.
  • Make sure your device’s operating software is up to date.
  • ResNet customers: Please do not unplug access points in your room; doing so affects not only your connectivity but your neighbors’ as well. 

Wi-Fi Service Desk Help Request Tips

If you do experience connectivity issues even after trying the suggestions listed above, request help from the Service Desk using one of the following three options.

If contacting the Service Desk via Web or email, you can help us expedite the process by providing as many of the following details as possible:

  • Your UC San Diego email address
  • Your phone number
  • The type of device you are having problems with
  • The location(s) you were in when having problems
  • The MAC address of the device you are having problems with. Read a Knowledge Base Article finding your MAC address 
  • The IP address of the device you are having problems with. Read a Knowledge Base Article on finding your IP address 
  • What network(s) (UCSD-PROTECTED, RESNET-PROTECTED, UCSD-GUEST, “can’t see any networks,”etc) you were trying to connect to and the time(s) you were trying to connect 

Wi-Fi Authentication System Status and Background

In 2020, IT Services replaced the authentication hardware and software that process usernames and passwords as devices connect to the UCSD-Protected network. The former system was not scalable for continued campus growth. We selected a best-in-class system and worked closely with the vendor's team on how to size and configure the system to handle the capacity of a fully re-populated campus in Fall 2021. 

Clearly, the configuration was not adequate to meet needs. The authentication system quickly became overwhelmed, with a failure in one area causing a chain reaction of other failures. IT Services was in constant communication with the vendor to implement repairs and fixes, such as drastically increasing authentication capacity, installing faster hardware and software and more effectively routing traffic and balancing loads. 

Since Thursday, September 30, 2021, Wi-Fi service, including authentication, has greatly improved. We continue to work closely with the vendor to identify ways we can improve it.

Last night’s electrical storm caused a power outage taking a number of network switches in various locations offline. Though not related to last week's authentication problem, this did impact wireless in some locations. Most of the switches impacted either came back up once power was restored or have been restored by our network team. More information on the status of this effort can be found at http://status.ucsd.edu.

Connectivity to Wi-Fi, VPN and Duo services has greatly improved since Thursday, September 30. The IT Services team made several changes last week including an additional authentication infrastructure and configuration changes to improve performance.

Though the service looks stable, we are continuing to monitor it closely and work with Cisco to identify ways we can improve it. Additionally, this week IT Services team members will be spreading out campuswide to test and verify connectivity and perform speed tests.

If you continue to have connectivity difficulties, contact the Service Desk:

UC San Diego Wi-Fi Current Status - October 1, 2021

Over the last two days we have continued to add additional equipment, fine tune authentication configurations and work with our network vendor, Cisco, to improve the authentication services that have been causing problems with Wi-Fi, VPN and Duo. In the last 24 hours our logs and outreach to students, faculty, and staff reflect an improved network experience. Since yesterday afternoon we have seen a substantial increase in successful connections AND decreases in failed connections during class transitions, which are peak times.

If you still experience connection issues, try the following:

  1. General users: Try UCSD-GUEST wireless if you cannot access UCSD-PROTECTED
  2. ResNet users: Try ResNet-GUEST wireless if you cannot access ResNet-PROTECTED
    • Password (PSK Key) is "ResnetConnect"
  3. If you've recently changed your AD password, delete and re-add UCSD-PROTECTED from your device
    • In your computer or phone’s network/Wi-Fi settings, select UCSD-PROTECTED 
    • Select “Forget” or “Forget Network”
    • Reconnect to UCSD-PROTECTED and re-enter your username and password

UC San Diego Wi-Fi Current Status - September 30, 2021 

We are experiencing issues with our Wi-Fi service that is intermittently affecting the ability to initially connect to our wireless network. IT Services is working around the clock to address the recent issues with campus Wi-Fi. The issues happen when initially connecting to Wi-Fi (or reconnecting later). The highest level of urgency and Cisco engineering support (our technology provider for this) by IT Services and Cisco is being allocated to resolving this issue as quickly as possible. 

The Cisco and IT Services teams continue to work around the clock implementing new configurations and adding additional capacity to the Wi-Fi environment. The Cisco and IT Services teams are making changes to improve the performance and we are monitoring the system to help improve performance when usage rapidly increases, primarily at the change of classes and during breakfast and lunch periods. The Cisco and IT Services teams will be implementing technical changes to the wireless service over the next several days to improve performance.

Here is what you can do now to help improve performance: 

  1. General users: Try UCSD-GUEST wireless if you cannot access UCSD-PROTECTED
  2. ResNet users: Try ResNet-GUEST wireless if you cannot access ResNet-PROTECTED
    • Password (PSK Key) is "ResnetConnect"
  3. If you've recently changed your AD password, delete and re-add UCSD-PROTECTED from your device
    1. In your computer or phone’s network/Wi-Fi settings, select UCSD-PROTECTED 
    2. Select “Forget” or “Forget Network”
    3. Reconnect to UCSD-PROTECTED and re-enter your username and password

Continue to watch this space for updates and workaround tips until the situation is fully resolved. We will be periodically posting updates to keep you informed of the situation.
