Troubleshooting TigerII WAP Tools: Common Issues & FixesTigerII WAP Tools are widely used for managing wireless access points, performing diagnostics, and optimizing wireless networks. While the suite is powerful, users sometimes run into configuration, connectivity, and performance issues. This article walks through the most common problems, explains likely causes, and provides step-by-step fixes, plus preventative tips to keep your TigerII environment stable.
Overview of TigerII WAP Tools
TigerII WAP Tools typically include utilities for scan and discovery, firmware updates, configuration templates, signal analysis, and logging. Familiarize yourself with the specific modules you’re using (for example: Discovery, Firmware Manager, RF Analyzer, and Config Push) before troubleshooting; different modules will have distinct logs and behaviors.
1) Device Discovery Fails
Symptoms:
- Tools do not find APs on the network.
- Discovery times out or only finds some devices.
Likely causes:
- Network segmentation (VLANs or subnets blocking discovery).
- Firewall rules blocking required ports (UDP/TCP).
- Devices using static IPs outside the discovery range.
- mDNS/SSDP or other discovery protocols disabled on APs.
Fixes:
- Verify network connectivity: ping known AP IPs from the machine running TigerII.
- Check VLAN/subnet configuration: ensure the management PC and APs share a routable path or configure routed discovery.
- Open required ports: consult TigerII documentation for protocol ports—commonly UDP broadcast ports and management TCP ports—and ensure firewalls allow them.
- Temporarily disable host-based firewall on the management workstation to test discovery.
- Use manual IP entry: when automatic discovery fails, add APs by IP to continue configuration.
Preventative tips:
- Maintain an inventory of AP IPs and VLANs.
- Enable centralized management VLAN for APs where possible.
2) Firmware Update Errors
Symptoms:
- Firmware upload fails or stalls.
- APs reboot repeatedly after update.
- Inconsistent firmware versions across the fleet.
Likely causes:
- Interrupted transfer due to network instability.
- Incompatible firmware image or corrupted file.
- Insufficient AP storage or memory.
- Power issues during update.
Fixes:
- Verify image integrity: check file checksum (MD5/SHA256) against vendor-provided value.
- Ensure stable connectivity: perform updates over wired management networks or schedule during low-traffic windows.
- Upload in smaller batches: reduce simultaneous updates to avoid saturating the network.
- Use the AP console/serial access: if an AP is bricked, use serial recovery procedures provided by the vendor.
- Check power stability: ensure UPS backup for critical infrastructure during updates.
Preventative tips:
- Test new firmware on a small pilot group before wide deployment.
- Keep rollback firmware images available.
3) AP Not Joining Controller / Management Server
Symptoms:
- AP shows as “unmanaged,” “pending,” or fails authentication.
- Repeated join attempts and failures.
Likely causes:
- Mismatched controller certificate or credentials.
- Time/date mismatch causing certificate validation errors.
- DHCP options (like option 43) not configured or incorrect.
- Controller discovery settings misconfigured (DNS entries, redirection).
Fixes:
- Verify controller hostname/IP: confirm the AP can resolve and reach the controller via DNS or direct IP.
- Check certificates and clock: ensure both controller and AP have correct system time and compatible certificates.
- Confirm DHCP options: ensure option 43/option 138 (vendor-specific) are set correctly for AP boot provisioning if used.
- Check shared secrets or pre-shared keys: re-enter and synchronize any required keys.
- Inspect logs on both AP and controller for TLS/auth errors, and address accordingly.
Preventative tips:
- Use NTP to synchronize time across devices.
- Maintain documented provisioning steps for DHCP and DNS.
4) Poor Wireless Performance / High Latency
Symptoms:
- Low throughput, high jitter, or frequent client disconnects.
- AP reports high channel utilization or retransmissions.
Likely causes:
- RF interference (co-channel or non-Wi‑Fi sources).
- Incorrect channel or power settings.
- Too many clients per AP or client-side issues.
- Firmware bugs affecting RTP or association handling.
Fixes:
- Run RF scans: use TigerII RF Analyzer to identify channel congestion and non-Wi‑Fi interferers.
- Reassign channels and adjust transmit power: prefer non-overlapping channels; lower power on dense deployments.
- Balance client load: enable band steering and client load-balancing features.
- Update drivers/firmware for APs and clients if specific bugs are known.
- Isolate problematic clients: check for devices causing high airtime usage and rate-limit or move them to wired connectivity.
Preventative tips:
- Design with proper AP spacing and channel planning.
- Use 5 GHz band for capacity when clients support it.
5) Configuration Push Fails or Inconsistent Settings
Symptoms:
- Some APs do not receive pushed configurations.
- Config changes revert or partially apply.
Likely causes:
- Network interruptions during push.
- Template incompatibilities (AP models not supporting certain features).
- Stale device cache on controller or tool.
Fixes:
- Confirm model compatibility: ensure your template features are supported by the AP firmware and model.
- Push in smaller groups: avoid mass pushes that may overload management channels.
- Clear device cache or re-sync device: force a config pull from the AP or refresh the controller’s device database.
- Check user permissions: ensure the account performing the push has adequate privileges.
- Monitor logs for specific config errors and correct syntax or incompatible options.
Preventative tips:
- Keep separate templates per AP family.
- Use staged rollouts and monitor logs.
6) Licensing or Feature Access Errors
Symptoms:
- Features disabled or limited despite appearing enabled.
- Licensing warnings or expired license messages.
Likely causes:
- License not applied correctly to controller or AP group.
- Time/clock mismatch causing validation failures.
- License limit exceeded (APs/users beyond licensed count).
Fixes:
- Verify license status in the controller UI and reapply license file if needed.
- Ensure system time is accurate for license validation (use NTP).
- Audit device count against license limits and remove or reassign where necessary.
- Contact vendor support if license server validation is failing externally.
Preventative tips:
- Track license expirations and device counts.
- Keep backup copies of license files and purchase history.
7) Log Collection & Analysis Issues
Symptoms:
- Logs missing or incomplete.
- Hard to correlate events across APs and controller.
Likely causes:
- Log rotation and retention settings too aggressive.
- Remote logging (Syslog/ELK) not configured or network blocked.
- Clock skew making events hard to sequence.
Fixes:
- Configure centralized logging: send logs to a dedicated syslog/SIEM with sufficient retention.
- Increase local retention temporarily for troubleshooting.
- Ensure timestamps are correct by using NTP across all devices.
- Use consistent log levels and enable debug only when necessary to avoid flooding.
Preventative tips:
- Implement a logging policy with retention schedules and indexing for search.
- Regularly archive logs and test log recovery.
8) Security & Authentication Problems
Symptoms:
- Clients unable to authenticate to secure SSIDs (WPA2/WPA3).
- RADIUS or 802.1X failures.
Likely causes:
- RADIUS server unreachable or credential mismatch.
- Certificate chain not trusted by clients or APs.
- Incorrect SSID encryption settings.
Fixes:
- Test RADIUS reachability: ping and test authentication using a test client or radtest.
- Verify shared secrets and user credentials.
- Check certificate validity and trust chain on RADIUS and APs; deploy intermediate CA certs if required.
- Review SSID configuration: ensure encryption type and EAP methods match RADIUS server configuration.
- Inspect RADIUS logs for detailed error messages and correct accordingly.
Preventative tips:
- Maintain a test user and device for authentication testing.
- Rotate RADIUS shared secrets and maintain certificate renewal schedules.
9) API or Automation Scripts Failing
Symptoms:
- Scripts using TigerII API return errors or timeouts.
- Automation jobs stall or only partially complete.
Likely causes:
- API version mismatch or deprecated endpoints.
- Rate limiting on the controller or management interface.
- Authentication token expiration.
Fixes:
- Check API documentation for version-specific endpoint changes and update scripts.
- Implement pagination and back-off retry logic to handle rate limits.
- Use long-lived tokens or refresh tokens; ensure scripts refresh auth before expiry.
- Log API responses fully to capture HTTP status codes and error payloads.
Preventative tips:
- Use versioned API clients and test automation in a sandbox.
- Add monitoring/alerting for failed automation runs.
