Guest Wi-Fi support troubleshooting checklist
A first- and second-line checklist for guest-network access issues.
Gather the basics
- User contact details, and whether the issue is recurring.
- The device: connected by Wi-Fi or wired; operating system and version; any recent OS/firmware upgrade, network-setting change, or new security app (VPN, antivirus).
- Scope: are other users at the site affected, and is there a pattern (same OS or device type, a recent major OS update)?
Triage by symptom
- Captive portal does not appear: confirm the correct SSID and a redirect-capable browser; rule out VPN/firewall/proxy; check the device is not on the MAC blacklist in the Administration Portal.
- No IP address: on a Service Gateway, verify in the Administration Portal that the MAC is registered and an IP is assigned, on the correct VLAN/IP network; on Cisco Meraki, check DHCP in the Dashboard (or with the customer’s external DHCP).
- Unexpected disconnects: check session and inactivity timers in the Administration Portal, network load or AP issues, and recurring errors for the MAC in the logs.
- Login or redirect fails: check in the Administration Portal whether the login attempt failed, and confirm the email domain or SAML credentials are not blocked by policy; test with the same credentials on a reference device.
- Cisco Meraki: verify the Walled Garden allows traffic to the captive-portal endpoints.
Escalating to second line
Collect the device MAC and IP, the user’s email/phone, timestamps and a description, the connection type and OS version, and the steps already taken.
