UoP-WiFi

UoP-WiFi is the official unified wireless network of the University of Peradeniya, deployed campus-wide to provide secure, reliable, and seamless internet access for students, academic staff, and non-academic staff.

Introduced as part of the university’s long-term digital infrastructure upgrade, UoP-WiFi replaces legacy Wi-Fi systems with a single, centrally managed network that ensures improved security, better performance, and consistent connectivity across university areas.

Overview

Access to UoP-WiFi is provided through individual university credentials, ensuring accountability and secure usage. Users are required to get registered via the University SSO portal. Once registered, devices can be connected to the UoP-WiFi SSID using the same credentials.

To access the new WiFi network, you'll need to register on the university portal (auth.pdn.ac.lk). Once registered, you can connect to the new SSID (UoP-WiFi) using your registered credentials.

Thus, you are required to:

  • Register on the university SSO portal: Visit the portal (https://auth.pdn.ac.lk) and follow the registration instructions. (instructions attached below)
  • Connect to the new WiFi SSID: Find the new WiFi (UoP-WiFi) and connect to it using your registered credentials.

If you encounter any issues, please don't hesitate to contact us.
