View: WiFi information and troubleshooting

Understanding how to troubleshoot wifi connectivity for View Plus monitors

Updated over a week ago

Use this guide if your Airthings View device connects to Wi‑Fi but drops offline, or you see data gaps, or is struggling to reconnect on a regular basis.

Before you start

  • Confirm your phone has a stable internet connection.

  • Stay close to the device during setup (avoid placing the device near metal surfaces, inside cabinets, or behind TVs.)

  • Make sure the device has power:

    • If you use batteries, install fresh batteries.

    • If you use USB‑C, confirm the cable and power adapter are working.

  • Check your router:

  • Confirm your Wifi router has 2.4 GHz network enabled

    • Newer routers sometimes combine 2.4 GHz and 5 GHz under the same WiFi name (SSID). If so, see if you can create a dedicated 2.4 GHz SSID (for example: HomeWifi-2.4) and connect the device to it

  • Check Wi‑Fi security mode

    • Set 2.4 GHz to WPA2‑AES (CCMP).

    • Avoid WPA3-only mode.

    • Avoid “WPA2/WPA3 Transition” mode if you can.

  • Do not use special characters in your Wifi name and password.

Fresh start: Power cycle your router and your View device

  • Power cycle the View device by disconnecting the USB‑C cable and removing the batteries. While your View device is without power, restart your router.

Fun fact: in Norway, resetting a device is called “svenskeknappen” or “swedish button”, while our neighbor friends from Sweden call this a “norwegian reset”.

  • After at least 10 minutes, reinsert batteries and/or reconnect the USB‑C cable, you should see the “Breathe better, Live better screen”

  • In your Airthings app, go to your device settings

You should see that your device is connected with Wifi and to which network it is connected to.

Check that you can see your Wifi network you would like to use for your monitor.

Router “smart” features can cause disconnects

Many routers include automatic updates and “smart” security features. After a router firmware upgrade, these features can become more aggressive or change behaviour.

In some cases, the router may incorrectly identify normal IoT traffic as suspicious and temporarily block or disconnect devices (false positives). This can look like “intermittent Wi‑Fi” even when your internet works fine for phones and laptops.

All these new smart/AI features have fancy names (names vary by router brand):

  • Band steering / Smart Connect / Client steering

  • AI Protection / Intrusion prevention (IPS) / “Security” features that block devices

  • “Advanced Wi‑Fi”

  • etc

If you use a mesh system, ensure the device is on the primary network (not a restricted IoT network with limited access), and try turning off steering.

Some routers advertise AI-based protection. If the protection feature is misconfigured, outdated, or simply too strict, it can accidentally block IoT devices like Airthings.

Simple troubleshooting (alternative 1)

Create a Guest network (solves most of the issues)

If you know how to access your router settings, create a Guest 2.4 GHz network and connect your View device to it. Routers usually do not enable all the smart features on a guest network.

Simple troubleshooting (alternative 2)

Test the device with another router.

We recommend at least 24 hours at a friend or another family member’s router.

Advanced troubleshooting

DNS and firewall/security checks

Some routers, security gateways, or custom DNS setups can block the View from reaching the services it needs.

DNS

  • Make sure your primary DNS server is working.

  • The View is unable to use a secondary DNS server.

  • If needed, set a static DNS on your router. You can use Google Public DNS:

    • Primary: 8.8.8.8

    • Secondary: 8.8.4.4

Firewall / security allow-list

Ensure no firewall or security feature on the router blocks outbound access to:

<aside> 🔒

If you have a “Parental controls”, “Threat protection”, “Advanced security”, or a separate firewall device, try disabling it temporarily to test, or add an allow rule for the domains above.

</aside>

DHCP and IP address settings

Some networks renew IP addresses very frequently, which can cause repeated reconnect behaviour.

If you can access your router’s DHCP settings:

  • Increase the DHCP lease time (avoid very short lease times).

  • Or reserve a fixed IP address for the device using its MAC address (DHCP reservation).

Disable “smart” steering and security features

If you find such features on your router, you can try to disable those.

Mesh network?

Ensure the device is on the primary network (not a restricted IoT network with limited access), and try turning off steering.

If you have many access points, try locking the device to the closest access point (feature availability depends on router brand).

If the issue is still not resolved

Contact Support and include:

  • Router brand and model

  • Whether you use mesh or extenders

  • Whether Guest Wi‑Fi worked

  • Whether a different router worked

Router brands/models we have seen reported in intermittent Wi‑Fi cases

This list is based on cases reported to Customer Success. Most of them got solved by a change in the router settings.

  • Bell (Canada)

    • Bell Giga Hub (also branded as Sagemcom, Borne Giga, FAST 5689E)

    • Bell Home Hub modem/router

    • Bell Fiber 4000 router

  • Ubiquiti / UniFi

    • UniFi access points and gateways (including UDM‑Pro)

    • Ubiquity Dream

  • Rogers (Canada)

    • Rogers Xfinity (3rd generation)

  • eero

    • eero Pro 6E (model S010001)

  • ASUS

    • RT‑AC87U

    • RT‑AC68U

  • TP‑Link

    • Archer 1800

  • Hitron

  • Technicolor (Telia)

  • MikroTik

    • hAP ax2

If you can’t find your router in the list, still follow the steps above. The most common fixes are: dedicated 2.4 GHz SSID, WPA2‑AES, setting static public DNS servers and turning off steering/security features.
