Cambium cnPilot captive portal and External Hotspot
Cambium access points can run a guest portal on the access point or hand guests to an external page. Here is how both work, from Cambium’s own guides, including the cnMaestro cloud limit that catches people out.
Not supported by VoqadoWiFi. Written from Cambium Networks documentation read on 7 October 2026.
What Cambium Enterprise Wi-Fi is and who runs it
Cambium Networks makes the cnPilot and Enterprise Wi-Fi access points, which can be managed standalone or through cnMaestro, available as a cloud service or on premises. Guest access is configured on the WLAN under Guest Access, either on the access point (Internal) or with an External Hotspot.
How the External Hotspot hands guests to your page
With an External Hotspot you enter the External Page URL. The access point redirects new guests there with parameters that include ga_ap_mac (the access point), ga_cmac (the guest device), ga_srvr (the access point’s IP address), ga_nas_id, ga_Qv (an encoded query string used internally) and, when present, ga_orig_url, the page the guest wanted.
Cambium’s integration guide shows a login form whose action is /cgi-bin/hotspot_login.cgi on the access point, so it is the guest browser that tells the access point to open the network. With the Clickthrough access policy, the guest only has to accept the terms.
There is one important limit. A Cambium staff answer on the Cambium community says posting directly from a web server is supported when the access point is managed through cnMaestro On-Premises, and does not work when devices are managed by the cloud version of cnMaestro.
Guest WiFi you can run on Cambium cnPilot and Enterprise Wi-Fi today
| Option | What it does | Source |
|---|---|---|
| Clickthrough | Guests get access after accepting terms and conditions, with no authentication. | Vendor docs |
| RADIUS | Guests enter a username and password checked by a RADIUS server. | Vendor docs |
| Local Guest Account | A username and password configured on the device. | Vendor docs |
| LDAP | Credentials checked against an LDAP server. | Vendor docs |
| External Hotspot | Guests are redirected to an External Page URL you host. | Vendor docs |
| Whitelist | Destinations reachable before the guest is authorized. | Vendor docs |
Clickthrough on the access point is the default access policy and already covers a simple terms page. The External Hotspot only adds value if the page you host does something more, such as keeping a guest list.
Timeouts and returning guests
Session Timeout sets how long a guest may stay online before authenticating again: 60 to 2592000 seconds, default 28800 (8 hours). Inactivity Timeout disconnects associated devices that send no data, default 1800 seconds.
MAC Authentication Fallback is for sites where guest access is only used when MAC authentication fails, so known devices skip the portal.
VoqadoWiFi and Cambium cnPilot and Enterprise Wi-Fi: the honest status
VoqadoWiFi does not support Cambium cnPilot and Enterprise Wi-Fi today. VoqadoWiFi works with two controller platforms: TP-Link Omada and Ubiquiti UniFi. On those, the controller sends each new guest to the VoqadoWiFi login page as an external captive portal, and VoqadoWiFi asks the controller to open the network once the guest signs in.
This page describes what Cambium Networks documents, so you can decide what to do with the hardware you have. It is not a setup guide for VoqadoWiFi, and nothing on it means VoqadoWiFi works with Cambium cnPilot and Enterprise Wi-Fi.
| Question | Answer |
|---|---|
| VoqadoWiFi status | Not supported by VoqadoWiFi yet |
| What the vendor calls the external portal | Guest Access, External Hotspot |
| How access is granted, as documented | Form post from the guest browser. After the guest signs in, the guest browser posts a small form back to the access point or router, which then opens the network. |
The browser post back to the access point is documented, but the cnMaestro cloud limit means it would only work for some Cambium sites, and it would need testing on Cambium hardware. VoqadoWiFi has not built it, and there is no date.
If you are choosing hardware now, the TP-Link Omada setup guide and the Ubiquiti UniFi setup guide show exactly what VoqadoWiFi needs. If you are keeping your current hardware, its own options above work today without us.
