Educating Today's Students To Succeed In Tomorrow's World

Bring Your Own Device Internet

The letters BYOD and the words bring your own device.
Continue on to Classlink with the Classlink logo.

Click here if you've already connected to the YCUSD BYOD WiFi network to continue on to Classlink.

Please note: this network is only available while you are on your school campus, not at home.
The YCUSD Information and Technology department equipped most students with Chromebooks for distance learning, but we were not able to cover every student.  We want to enable those students that do not have a district-issued device to use their own, safely, on our network.  YCUSD_BYOD should help with that.
YCUSD_BYOD is now being broadcast at school sites.  Connecting to this network is easy (kind of like the wifi at a hotel), but will require that personal devices walk through an installation of our certificate for security purposes.  Here is what to expect:
  • Connect your personal device to YCUSD_BYOD using the passphrase "education" (no quotes).  Once connected, the device may say 'no internet'.  This is normal.
  • Open a browser and browse to 
  • The browser will be redirected to a 'Terms and Conditions' page.  Click Accept and Continue:
  • The browser will now be redirected to our BYOD landing page.  In order to ensure the safety of our students and staff online and protect our network, personal devices must follow the instructions for their device in the BYOD tabs ONLY ONCE (the first time they connect).  From then on, personal device users can 'Continue on to Classlink' when they reach this page.
