Matter over Wi-Fi requirements: 2.4 GHz, IPv6 and your router

Updated October 20, 2026 · Steps paraphrased from each platform's or maker's own help pages, linked beside each step. We have not tested these steps ourselves.

Short answer

Do Matter Wi-Fi devices need 2.4 GHz?

Usually, yes. Apple says some accessories cannot use 5 GHz networks, Home Assistant says Matter Wi-Fi devices often use 2.4 GHz, and TP-Link and Govee require a 2.4 GHz network for setup. Put your phone on the same 2.4 GHz network the device will use.(Apple: if you can’t add; Home Assistant: Matter; TP-Link sharing guide; Govee)

Your router also needs IPv6 turned on (Google and Govee require it), and the phone, the hub and the device should share one local network: not a guest or IoT network, not a separate VLAN.(Google: prepare for Matter; Govee; TP-Link troubleshooting)

2.4 GHz or 5 GHz

If the Home app says the network is incompatible, Apple says to connect your iPhone or iPad to a Wi-Fi network that supports 2.4 GHz, because some accessories do not work on 5 GHz.(Apple: if you can’t add)

If SmartThings shows the network as not compatible, Samsung says to check that the device supports that band (2.4 GHz or 5 GHz) and the network’s security type.(Samsung SmartThings)

TP-Link warns that some hubs on a 5 GHz-only network pass that network’s details to a device that only supports 2.4 GHz; its fix is to set the device up in the Tapo or Kasa app first, then add it to the other app. For Alexa, it says to pick your 2.4 GHz network on the Wi-Fi screen within five seconds.(TP-Link troubleshooting)

IPv6

Google says IPv6 must be on for Matter to work properly: without it, setup can seem to work, but control fails later. Check your router’s manual or ask your internet provider.(Google: prepare for Matter)

Home Assistant says Matter relies on local IPv6 and multicast (mDNS) traffic moving freely on your network, and does not need an IPv6 internet connection.(Home Assistant: Matter)

Govee lists an IPv6 network as a requirement for its Matter devices.(Govee)

One network for the phone, the hub and the device

TP-Link calls this the most important part of setup: keep the hub and the devices on the same local network, and if either is on a guest network, an IoT network or another VLAN, move both to your main network.(TP-Link troubleshooting)

Apple asks for your iPhone or iPad, your accessories and your home hubs to be on the same Wi-Fi network.(Apple: if you can’t add)

Home Assistant adds that Matter is built for ordinary home networks and may not work well with VLANs, multicast filtering or faulty IGMP snooping, and that router settings that “optimize” multicast can block Matter discovery. Keep the network simple and flat.(Home Assistant: Matter)

Changing your router or Wi-Fi network

Govee says that if you use the Govee Home app to switch a device to another network, its Matter function turns off, and you must reset the device and add it to your Matter app again.(Govee)

The platform pages we read do not cover moving a Matter device to a new Wi-Fi network. Ask the device’s maker first; for a device that no longer responds, Apple and Samsung both list removing it, resetting it and adding it again.(Apple: not responding; Samsung SmartThings)

Bluetooth and the setup window

During setup the phone talks to the device over Bluetooth, so keep Bluetooth on. TP-Link and Govee give a 15-minute window after the device powers on to finish Matter setup; power-cycle the device if it runs out.(Home Assistant: Matter; TP-Link troubleshooting; Govee)

Frequently asked questions

Do Matter devices work on 5 GHz Wi-Fi?

Some do not: Apple says some accessories are not compatible with 5 GHz networks, and TP-Link and Govee require 2.4 GHz for setup. Check the device’s box or its maker’s page for the band it supports.

Does Matter need IPv6?

Google says IPv6 must be enabled on your home network for Matter to work properly, and Govee lists it as a requirement. Without it, Google says control can fail even when setup seemed to succeed.

Can Matter devices be on a guest network or VLAN?

TP-Link says to keep the hub and the device on the same main network, not a guest or IoT network or another VLAN, and Home Assistant says VLANs and multicast filtering can stop Matter from working well.

Do I need to set up my Matter device again after changing routers?

Govee says switching a device to another network turns its Matter function off, so you reset it and add it again. For other brands, check the maker’s instructions.
