Authentication & Access Issues

No.TopicUniversity Helpdesk Should Check
1WiFi Not Working for a StudentIs the student connecting to the correct SSID?
Is the issue location-specific or campus-wide?
Can other students connect in the same area?
Check if the user is blocked (MAC filtering, captive portal auth, etc.)
2Unable to Connect to Captive Portal / Authentication FailsCan the student reach the captive portal login page?
Are credentials correct (if using SSO or university login)?
3802.1X Authentication Failure (Eduroam / University Login)Verify user credentials work on other university systems.
Ensure correct login format.
4Unauthorized Devices Joining the NetworkReview MAC address whitelist/blacklist policy.
Enable 802.1X or captive portal enforcement.
Check logs for repeated failed or spoofed attempts.
5Clients Can’t Communicate on Same SSID (e.g., AirDrop, Gaming)Check if client isolation is enabled.
6WiFi Disconnects When Using VPN or Certain AppsIs it app-specific or VPN profile-related?
Inspect firewall/IPS logs for blocked tunnels.

Connectivity & Signal Issues

No.TopicUniversity Helpdesk Should Check
1Students Can't See the SSIDIs WiFi enabled on the student’s device?
Are other nearby students seeing the SSID?
2WiFi Works in One Location but Not AnotherIs the affected building on the same VLAN and SSID?
3Access Point Offline / Not DetectedVerify AP power (PoE switch port status).
Check if cable is unplugged or port shut down.
4Students Getting IP Address Conflict or No IP AssignedIf any static IP has been assigned manually by the student.
Confirm DHCP server is reachable.
5Duplicate SSID Seen / Conflict with Other NetworksAre multiple SSIDs with the same name appearing?
Is this occurring in a student dorm or shared building?
6Wireless Printer or IoT Device Won’t ConnectIs the device 2.4GHz-only?
Is it trying to connect to a hidden or secured SSID?
7Student Can't Connect Because Device Uses Outdated WiFi StandardCheck if device is 802.11b/g-only.

Internet Access & Network Routing

No.TopicUniversity Helpdesk Should Check
1Students Can’t Reach Internet but Connected to WiFiCan the student ping the gateway or access internal university sites?
Check if browser proxy settings are interfering.
2WiFi Working but Some University Systems InaccessibleConfirm IP subnet has routing to internal systems.
Validate VLAN-to-VLAN routing and ACLs.
Check DNS for internal resolution issues.
Test from wired and wireless for comparison.

Performance & Stability

No.TopicUniversity Helpdesk Should Check
1Intermittent Connection / Dropped SignalIs the student moving between buildings (roaming)?
Check interference sources (microwaves, metal walls, etc.)
2Slow WiFi PerformanceIs this a peak usage period (e.g., lunchtime)?
Are many students affected or just a few?
3High Client Retry or Packet Loss RatesCheck APs availabilities.
4Client Devices Frequently Switching Between 2.4GHz and 5GHzSuggest clients "forget and rejoin" network to reset behavior.

Roaming & Mobility

No.TopicUniversity Helpdesk Should Check
1Issues with Roaming Between APsDoes the issue occur while moving between classrooms or buildings?
2Clients Frequently DeauthenticatedCheck controller for deauth reasons (e.g., idle timeout, auth failure, AP reassociation).

Infrastructure & Controller Issues

No.TopicUniversity Helpdesk Should Check
1Controller Unreachable / GUI Not LoadingPing the controller IP from inside and outside the network.
Check for DNS resolution issues.
2Controller License ExpiredContact TTHC Support.
3Controller Showing “High CPU” or “Memory Usage”Contact TTHC Support.
4Controller Cannot See Some APs After Power OutageAre APs powered and PoE switches up?

Policy & Configuration

No.TopicUniversity Helpdesk Should Check
1Bandwidth Abuse / User Throttling RequestIdentify suspected users or heavy downloaders.
2WiFi Blocking Access to Certain Apps (e.g., WhatsApp, YouTube)Is this an intentional university policy?
