UniFi Network 11: Phone Hotspot Backup and What Else Changed

UniFi Network 11 gives a UniFi gateway a new way to survive an internet outage. It can join a nearby Wi-Fi network, including your phone's hotspot, and carry on over cellular data. A home office or a small shop will notice that feature first, so it gets most of this article. The article flags anything Ubiquiti has not documented.

What is WiFi Uplink in UniFi Network 11?

WiFi Uplink lets a UniFi gateway connect to a nearby Wi-Fi network and use it as backup internet. Ubiquiti's Network 11 announcement calls the same feature WiFi WAN and says it works with a phone's hotspot. The gateway sends traffic out through the phone's cellular data instead when your main connection fails.

Ubiquiti uses two names, so search for both. The announcement describes WiFi WAN as a primary or backup connection. The 11.0.81 release notes list WiFi Uplink as an internet backup. Plan around the backup role until Ubiquiti publishes a help article.

How an outage plays out

UniFi gateways already follow documented failover rules for wired internet links, which Ubiquiti's WAN failover help article spells out. Ubiquiti has not said whether WiFi Uplink follows the same rules, so read the cards below as the probable sequence.

Which UniFi gateways support WiFi Uplink?

The 11.0.81 release notes list four: the Dream Router 7 (UDR7), Dream Router 5G Max (UDR-5G-Max), Express 7 and Cloud Gateway Industrial (UCG-Industrial). All four need UniFi OS 6.0.10 or newer. Ubiquiti lists no other gateway, and the announcement names none.

The list leaves out gateways that many homes and offices run today, including the Dream Machine Pro and the Cloud Gateway Max. All four listed models carry a built-in Wi-Fi radio, which suggests the gateway joins the hotspot over its own radio, though Ubiquiti has not confirmed that. We install the Dream Router 7 in many condo and townhouse networks, and our UniFi Express 7 mesh Wi-Fi article covers the Express 7. If your gateway is not on the list, a dedicated cellular device does the same job (see the comparison below).

How well does a phone hotspot work as backup internet?

A hotspot handles email, web apps and card payments for the length of an outage. It struggles when many people use it at once, and it depends on one phone staying charged, awake and in range of a good cell signal. Six limits decide whether it suits you.

• The phone has to stay on. Phones switch hotspots off on their own to save battery, and some do it when no device is connected. Plug the phone in, turn off the hotspot auto-off setting where your phone offers one, and test it overnight.
• The phone has to stay home. A spare phone on a charger near a window works as a backup. A phone in your pocket leaves the building with you.
• Signal sets the speed. Reception inside a condo tower or a concrete basement can be weak. Put the phone where the signal is best and run a speed test on it before you need it.
• Data has a limit. Hotspot data comes out of the phone plan, and some plans cap tethering at full speed and then slow it. Streaming HD video can use about 3 GB an hour, so one movie night on backup can empty an allotment. Read your plan's hotspot terms.
• Inbound access stops. Most cellular providers put phones behind carrier-grade NAT, so port forwards, self-hosted servers and some VPN servers cannot reach you on backup. Outbound traffic such as email, cloud apps and cloud-managed UniFi access keeps working.
• Your public IP changes. A supplier portal or bank that restricts logins to your office IP address can refuse you while you run on backup.

Give the hotspot jobs that fit these limits, such as email and card payments.

Phone hotspot, 5G backup box or second ISP: which fits?

A phone hotspot costs nothing extra and fits a home or home office that can live with a slower connection for a few hours. A dedicated 5G or LTE device suits a shop or office that needs the backup to work without anyone's phone. A second internet provider on a spare WAN port suits a business where an hour offline costs sales.

Ubiquiti's 5G and LTE backup guide describes two modes for its cellular devices. In the first, you plug the device into a PoE port and it acts as a LAN-connected backup. All networks use it by default, and you can switch it off per network under Settings, Networks. In the second, you wire a 5G Max or U5G to a WAN port as a primary connection. Ubiquiti tells owners to set a data limit and a usage warning on the device. Prices come from Ubiquiti's Canadian store as of October 12, 2026.

Put essential devices on the backup and leave the rest off

Card terminals, office phones and the laptops that run your cloud apps belong on the backup. Guest Wi-Fi, TVs, game consoles and software updates do not, because backup data is scarce and a short device list makes it last.

For wired connections, Ubiquiti's WAN failover article shows how Policy-Based Routing dedicates a link to chosen traffic such as VoIP, guest Wi-Fi, camera streams or IoT. On its 5G and LTE devices you can also turn the backup off for individual networks. Ubiquiti has not documented those controls for WiFi Uplink, so confirm they exist before you count on the feature.

UniFi Protect records to local storage, so an outage does not stop recording. Remote viewing and push alerts need internet, and live video over a hotspot burns data fast. Keep camera streams off the backup unless you must watch from off-site during an outage. Our UniFi Protect video evidence guide covers recordings that hold up as evidence.

What else is new in UniFi Network 11?

Network 11 adds Live Flows, External Network Lists, SD-WAN failover policies, AI threat explanations and Matter and Thread monitoring, on top of a faster statistics engine. Ubiquiti also changed the database, the firewall model and the platform requirements, and those changes weigh more in your update decision than the new features.

• More capacity, new statistics engine. Ubiquiti reports more than 30% better scalability from a re-engineered telemetry engine, and the database moves to PostgreSQL. VLAN capacity grows too, though Ubiquiti gives no number.
• Live Flows. Watch active connections on the gateway as they happen and end one on demand. Flows also show the firewall policy that allowed them, with an application column and filter. Needs UniFi OS 6.0.10 or newer.
• External Network Lists. Network Lists can import domains or IP addresses from a web address and refresh themselves, which keeps firewall rules and VPN routes current without manual edits. Needs UniFi OS 6.0.10 or newer.
• SD-WAN failover and app routing. New policies handle failover and per-application routing across several UniFi sites, under one rule set. It targets businesses with more than one office.
• AI threat explanations. Cybersecure Enhanced alerts now explain scope, risk and impact in plain language and suggest next steps, on top of daily Proofpoint threat signature updates.
• Matter and Thread monitoring. Add Matter devices by pairing code and watch their battery, firmware and signal. The release notes call this device monitoring, and it needs mDNS and IPv6 turned on.

Smaller changes include a Time Machine view on the Topology page that replays network changes, bulk editing of connected devices and generated device icons. If you run several locations, our UniFi Network 10.5 notes cover the SD-WAN underlay work that came before this release.

Should you update to UniFi Network 11 now?

Update now if you want WiFi Uplink, run a simple setup on a supported gateway, and know how to roll back. Wait if you run custom firewall rules, a third-party router behind your UniFi gateway, or a business that cannot absorb a bad night. Early reports describe 11.0.81 as an Early Access build, and some owners on Ubiquiti's community have reported routing and firewall problems after upgrading.

Changes the update makes to your network

• Zone-Based Firewall migration. The update migrates all sites to the Zone-Based Firewall. Review the rules between VLANs after it runs, including those for printers, smart-home devices and servers. Early reports say custom rules can change behaviour after the move.
• Statistics reset. Existing history clears, and the new engine rebuilds it from zero.
• A short outage. Devices re-provision after the update, and the upgrade can take up to 20 minutes. Run it after hours.
• A higher platform floor. Network 11 needs UniFi OS 6.0 or newer, and WiFi Uplink, Live Flows and External Network Lists need 6.0.10.
• Older gear is cut off. Ubiquiti dropped USG gateway support, and Network 10.6 is the last release for them. It also dropped the standalone Network Application server and points self-hosters to UniFi OS Server.
• Third-party routers. In early reports, setups with another router behind a UniFi gateway lost access to subnets behind it. Test before you rely on that layout.

Export a configuration backup, store it off the console, and decide how you would roll back to the 10.6 line before you start. Our recommendation: update a supported gateway now if backup internet solves a problem you have today. If it does not, wait for the general release, then update after a backup and a firewall review.

Ubiquiti has not answered five questions about WiFi Uplink

Ubiquiti has published no help article for WiFi Uplink, so five practical questions stay open. Settle them before you buy a gateway for the feature.

• Primary or backup? The announcement says either. The release notes say backup.
• Radio sharing. Does joining a hotspot take airtime from your own Wi-Fi network, and does that cost speed?
• Timing and tuning. How fast does it fail over and fail back, and can you change the health checks?
• Network limits. Can you keep chosen networks off it, as you can on Ubiquiti's cellular devices?
• More gateways. Will gateways beyond the four listed get it later?

A backup link keeps your network working through an outage. Your provider stays responsible for the service it delivers to the property. If repeat outages are your problem, read what an outage log showed in an Etobicoke home.
