Access the UniFi Network Controller & Guest Wi‑Fi Basics

Summary

Where the UniFi controller lives, how to reach it, and the basics of the guest network. BBN typically manages the controller centrally — customers should contact BBN for changes.

Where the controller runs

UniFi is managed from one of:

• A UniFi OS Console — Cloud Key (UCK), Dream Machine (UDM/UDM‑Pro/UDR), or Dream Wall — reached at https://<console-ip> or via unifi.ui.com (remote access).
• A self‑hosted/hosted controller (software on a server) — reached at https://<controller-ip>:8443.

Access it

1. Remotely (recommended): sign in at unifi.ui.com with the Ubiquiti SSO account that owns the console. You'll see the site and can open UniFi Network.
2. Locally: browse to https://<console-ip> (UniFi OS) or https://<controller-ip>:8443 (software), accept the certificate warning, and sign in with the local admin credentials.
3. Don't have access? Contact BBN Support — controller access is restricted for security.

Guest Wi‑Fi basics (Technician)

1. In UniFi Network → Settings → WiFi, guest SSIDs are separate networks flagged as Guest.
2. Guest network / hotspot policy (Settings → Networks / Hotspot 2.0 / Guest Control) controls the captive portal, password/voucher, and client isolation (guests can't see each other or the internal LAN — keep this on).
3. Guest can't get internet: check the guest SSID is enabled, the captive portal auth is correct, and the guest VLAN has a working DHCP scope + internet route.

Common tasks (usually via BBN)

• Change a Wi‑Fi password, add an SSID, create guest vouchers, or adjust VLANs — these affect the whole site, so raise a ticket with BBN Support rather than changing live.

If that doesn't work

• Can't reach the console at all → it may be offline/rebooting, or its IP changed; check on‑site or with BBN.
• Escalate to BBN Support for controller access or any network change.

Prevention

• Keep client isolation on for guest Wi‑Fi; document the console IP + SSO owner with BBN.
