Wi‑Fi won't connect or frequently disconnects

Harmony connects to your Wi‑Fi network to sync with the Harmony cloud. The article will help you troubleshoot Wi‑Fi issues with Harmony.

Wi‑Fi issues during setup

If Harmony Hub isn't discovering or connecting to your Wi‑Fi network, try the following:

  • Ensure your Wi-Fi password doesn't contain an emoji — they are not supported by Harmony.
  • Unplug the hub from the power adapter, wait 10 seconds and then plug it back in. The Hub will take 30 seconds to power on.
  • Power cycle your router by unplugging it from its power adapter, waiting 10 seconds and then plugging it back in.
  • Move the hub closer to your router to eliminate range issues.
  • Confirm that your router is broadcasting in 2.4GHz, and not limiting to 5GHz. (see system requirements)
  • If your router is not broadcasting its name or SSID, select Hidden Network from the Wi‑Fi screen and manually enter your information.
  • Use another device to connect to the Wi‑Fi network and confirm that it's able to access the internet.

Hub and app connections

If Harmony Hub connected to Wi‑Fi during setup, but the Harmony mobile app is not able to discover it, try the following:

  • Check that the Harmony mobile app is connected to the same Wi‑Fi network name as Harmony Hub.
    • Harmony Elite and Ultimate remotes can check what Wi‑Fi network the hub is on by navigating to Menu > Settings > General > About.
  • Unplug the hub from the power adapter, wait 10 seconds and then plug it back in. The hub will take 30 seconds to power on.
  • Power cycle your router by unplugging it from its power adapter, waiting 10 seconds and then plugging it back in.
  • If you have a 2.4GHz and 5GHz compatible router, try connecting your mobile device to the 2.4GHz network. Harmony Hub is not compatible with 5GHz Wi‑Fi frequencies.

Troubleshoot your router settings

Some routers have a setting that prevents two Wi‑Fi devices from communicating with each other, and will only allow a Wi‑Fi connected device such as your mobile device to communicate with devices connected using a network cable. This is referred to as Internal Station Connection by many manufacturers, but not universally. Here's a list of other common names for this setting.

  • Manufacturer
    Setting Name
  • Asus
    AP Isolation
  • Cisco
    Wireless Isolation
  • D-Link
    WLAN Partition
  • Linksys
    AP Isolation
  • Netgear
    Wireless Isolation

Refer to your router's user manual for instructions on how to disable this.

Troubleshoot using the desktop software

Use these steps to re-configure Wi‑Fi settings using the MyHarmony desktop software.

  1. Sign into your account using the MyHarmony desktop software.
  2. Select your remote from the Remote Gallery.
  3. Select the Settings tab on the left side of the screen.
  4. Select Set up / Change Wi‑Fi Settings and follow the on screen prompts.

Troubleshoot your hub and app connection

If the the Harmony mobile app was working with the Harmony hub but is no longer able to establish a connection, you may be able to perform a deeper network scan to re-establish communication.

  • From the CONNECT TO HUB screen, wait approximately one minute for your hub to appear.
  • If your hub does not appear, press the ( ? ) icon in the upper right corner.
  • Select Advanced Scan, and the Harmony mobile app will try to discover your hub on all possible IP addresses.
    If your router is configured to assign Harmony Hub a static IP, you may also enter it manually.

  • Harmony App - Advanced hub connection

Connect to your hub manually

If the advanced scan does not work, the Connect Manually button allows you to make a Bluetooth connection between the Harmony mobile app and hub so network information can be shared.

  • From the CAN'T FIND HUB troubleshooting screen, select Connect Manually.
  • If you don't currently have Bluetooth enabled, the app will prompt you to turn this on.
  • You will be prompted to initiate pairing between the app and hub by pressing the Pair/Reset button on the back of the hub.
  • Once pairing is complete, the Harmony mobile app should be able to discover the hub using Wi‑Fi.

  • Harmony App - Connect to hub manually

Frequently disconnects

If your Harmony hub successfully connects to Wi‑Fi but frequently disconnects:

  • Move Harmony Hub closer to your router.
  • Upgrade the firmware on your router which may help address connection issues.
  • Change the channel frequency of your router to help prevent interference. Consult your router's user manual for channel changing steps.
  • Check if other household items interfere with your Wi‑Fi network when they are turned on. Common culprits are microwaves, cordless phones and baby monitors.

Router support

Harmony is compatible with 2.4GHz band Wi‑Fi routers that support 802.11 g/n standards and WEP 64/128, WPA Personal and WPA2-AES encryption. Harmony does not support 5GHz frequencies, the 802.11 a/b standard, nor WPS.

However not all routers are created equal and some customers have reported incompatibility with:

  • Actiontec M142WR
  • D-Link DIR655A (Hardware version A4)
  • Trendnet TEW-633GR
