Checked 1 November 2026. Three 5G Hub NR5103E V2 (Zyxel), from Three’s device guides as of 2026, with the Three app for iOS and Android. Three’s guides for the older NR5103E and for its ZTE and Green Packet hubs differ.

Sign in to the Three 5G Hub

  1. Connect your Mac to the hub by Wi-Fi or Ethernet.

  2. Open http://192.168.1.1 in your browser.

  3. Enter the admin login details from the back of the hub and click Login.

  4. Or open the Three app, which asks you to scan the login QR code the first time.

During set-up the Three app offers to change the login password. To change it later, tap the Settings tab, then Router management, and enter the current and new password. Forgotten it? A factory reset restores the label password and erases your settings.

Restart it properly

  1. Open the Three app and tap the Settings tab.

  2. Tap Restart hub.

  3. Wait several minutes, until the power light is solid green again.

The reset button on the bottom restores factory settings when pushed in for more than 5 seconds with a thin object. Don’t use it to restart.

  2. Press it again to switch the hub on.

2.4 and 5 GHz, and the channel

By default the hub merges both bands under one network name. Unmerging them gives the 5 GHz band its own settings. The 2.4 GHz band can’t be switched off.

  1. In the Three app, tap the Network tab, then the Wi-Fi tab.

  2. Tap Configure Wi-Fi.

  3. Turn off Merge 2.4 and 5GHz bands. You may be disconnected for a few minutes.

  4. Once you are back, tap 5GHz to change its name or switch it off, then tap Save changes.

Change the Wi-Fi name and password

  1. Tap Network › Wi-Fi › Configure Wi-Fi.

  2. Tap 2.4GHz and 5GHz bands.

  3. Change the name or password and tap Save changes.

Change the channel

Three’s device guides document no channel setting for the 5G Hub.

Mesh: which node a device uses

  2. Tap Configure Wi-Fi, then the Guest tab.

  3. Tap 2.4GHz and 5GHz bands and turn the switch on.

Connection status and logs

Three says where you put a 5G hub matters most: a better signal gives better speeds. The app shows the signal so you can find the best spot.

  1. Open the Three app; the home screen shows the hub’s signal strength.

  2. Move the hub and watch the signal to find the best place for it.

  3. For data usage, sign in at http://192.168.1.1 with the admin password and select Tools.

  4. For an outage, check Three’s Coverage Checker or Network Status Checker.

The hub has lights for power and system, internet, signal strength and Wi-Fi/WPS. Three’s guides only describe the power light: solid green when the hub is ready.

Questions

Why can’t I switch off the 2.4 GHz band?

Three says the 5G Hub doesn’t allow it. You can only switch off 5 GHz, after unmerging the bands in the Three app.

Which password opens the hub’s settings?

The admin password on the label on the back, unless you changed it during set-up. It is different from the Wi-Fi password.
