# Chunghwa Telecom HiNet Wi-Fi全屋通 login, restart, devices and Wi-Fi

Wi-Fi全屋通 (whole-home Wi-Fi) is the mesh Wi-Fi access point Chunghwa Telecom rents to HiNet 光世代 (fibre) customers, plugged into the HiNet fibre modem. You manage it in the 中華電信Wi-Fi全屋通 app or in a browser at `mymeshdevice.home`.

Wi-Fi全屋通

Sign in

`mymeshdevice.home` or `192.168.0.1`

App

中華電信Wi-Fi全屋通 (iOS and Android), used while the phone is on the Wi-Fi全屋通 network.

Password

The Wi-Fi name (`CHT Wi-Fi Home-` and three characters on the WX3400-T0) and Wi-Fi key are on the label on the back. The admin password, which the app calls the **管理者密碼** (Administrator password), is a separate thing.

Models

Zyxel WX3400-T0, Arcadyan WG620443-TC, Arcadyan WG630223-TC, Arcadyan WE410443-TC, Arcadyan WG420223-TC

**Checked 1 November 2026.** App paths checked in the Wi-Fi全屋通 App manual (Ver. 115-02, February 2026), which covers the Zyxel WX3400-T0 and the Arcadyan WG620443-TC, WG630223-TC, WE410443-TC and WG420223-TC. Browser paths are from the WG620443-TC and WG630223-TC quick guides (September 2025); the WX3400-T0 guide (April 2026) gives only the login. Chunghwa Telecom publishes no guide for the fibre modem’s own settings.

## Sign in to the Wi-Fi全屋通

**Factory default.** Chunghwa Telecom’s guides give user name `user` and password `user` for the browser, and `user` for the app. The browser makes you choose a new password the first time; change the app password too.

1. Join the Wi-Fi全屋通 network, not a guest network, or plug into the access point’s LAN port.
2. Open `https://mymeshdevice.home` in a browser, or `https://192.168.0.1` on the WX3400-T0.
3. Enter the **Username** and **Password**, type the verification code shown, and sign in.
4. On the first sign-in, set your own password on the **Update Password** page.
5. In the app, enter the 管理者密碼. To change it later, tap **設定 › 變更管理者密碼** (Settings › Change administrator password).

Forgotten the admin password? Hold the **WPS** button on an Arcadyan unit for over 6 seconds, or **Reset** on the WX3400-T0 for 5–10 seconds, to restore `user`. Holding **Reset** for 10 seconds or more is a factory reset. The app can turn off the WPS password reset under **變更管理者密碼**.

## Restart it properly

1. Open the app and tap **設定 › 設備重啟** (Settings › Restart devices).
2. Tap the network name to restart every access point on it.
3. Tap **確認** (Confirm) and wait for the restart.
4. Reconnect to the Wi-Fi and sign in to the app again.

A restart cuts the Wi-Fi for everyone. Don’t hold the reset or WPS buttons to restart: they reset the password or the whole unit.

### Restart one access point

1. On the **網路拓樸** (Network topology) tab, tap the access point.
2. Tap **設備重啟** (Restart device), then **確認**.

### Schedule a restart

1. Tap **設定 › 設備重啟**, then **+** or the network name.
2. Switch it to **開啟** (On).
3. Choose the repeat, start date and restart time.
4. The page then shows the next restart time.

### Power-cycle the modem and Wi-Fi

1. Switch off the fibre modem and the Wi-Fi access point.
2. Wait at least 30 seconds.
3. Switch on the modem first and wait one minute.
4. Switch on the Wi-Fi access point and check that the lights turn green or blue.

**Kilobat can help.** Kilobat Pro’s [router check-up](https://kilobat.app/docs/home-network#router-checkup) learns how fast this router usually answers, says when a restart is due, and checks the next day whether it helped.

## Update the firmware

Chunghwa Telecom documents no way to check or install firmware yourself. Updates arrive on their own: the front light flashes purple on the Arcadyan Wi-Fi 6 units, and **Power** flashes red on the WX3400-T0, while one installs. Leave the power on.

## See connected devices

1. Open the app and tap **裝置** (Devices) at the bottom.
2. Tap a device to see its connection details.
3. Tap **修改名稱** (Rename) to give it a name you’ll recognise.
4. To see devices on one access point, tap it on **網路拓樸**, then the connection count.

Devices are told apart by MAC address. Phones using a private Wi-Fi address can show up under a strange name, and blocks or time limits may miss them.

### Block a device

1. Tap **設定 › 黑名單管理** (Settings › Blacklist).
2. Tap **+** or **新增黑名單** (Add to blacklist).
3. Choose the device and save.

A blacklisted device can never join that network. To lift it, tap the padlock beside it.

**Kilobat can help.** Kilobat’s [new-device alerts](https://kilobat.app/docs/home-network#new-devices) tell you when a device you haven’t seen joins your home Wi-Fi. **Tools › Devices** lists what answers on the network, and you can name each one.

## UPnP and port forwarding

Chunghwa Telecom’s app manual and quick guides for the Wi-Fi全屋通 units describe no UPnP setting, and no NAT-PMP either.

**Kilobat can help.** Without UPnP traffic counters, Kilobat’s [call reports](https://kilobat.app/video-calls) still name a busy app on your Mac or a Wi-Fi problem, but can’t point at another device at home.

## Prioritise calls and gaming

There is no QoS or device priority setting. The app can only limit when devices go online.

### Limit a device’s online time

1. Tap **設定 › 上網時間管理** (Settings › Online time management) and switch it on.
2. Tap **新增時間管理時段** (Add a time period).
3. Choose the devices, then tap **下一步** (Next).
4. Name the period, pick the days and the start and end times, and tap **儲存** (Save).

**限時隔離管理** (Timed isolation) cuts off chosen devices straight away for a set time.

**Kilobat can help.** Run Kilobat’s [stutter test](https://kilobat.app/guides/recipes/test-call-stutter) before and after you change priorities, to see whether calls really got smoother.

## 2.4 and 5 GHz, and the channel

The access points pick the channel themselves from signal strength and traffic. Chunghwa Telecom’s own walkthrough shows the app running 2.4 GHz and 5 GHz under one name or separately.

1. Open the app and tap **設定 › Wi-Fi管理** (Settings › Wi-Fi management).
2. Tap **更改設定** (Change settings) beside the main network.
3. Switch the 2.4GHz or 5GHz band on or off.
4. To rename the network or change its key, tap **詳細設定** (Details), edit, and tap **儲存**.

### Change the channel

1. Sign in at `https://mymeshdevice.home`.
2. Click **Settings › Wireless**.
3. On **Wireless Settings**, set the 2.4GHz or 5GHz channel and channel width, then save.

Checked on the Arcadyan WG620443-TC and WG630223-TC guides only.

**Kilobat can help.** Kilobat shows which band and channel your Mac is on, and `kilobat channels` suggests the least crowded channel. More in [crowded Wi-Fi channels](https://kilobat.app/guides/wifi-channel-congestion) and [Wi-Fi on a Mac](https://kilobat.app/wifi-analyzer-mac).

## Mesh: which node a device uses

1. Open the app; the **網路拓樸** tab shows the modem and every access point under it.
2. Tap an access point to see its signal strength, device info and connected devices.
3. Check the light on each extra unit for its link to the main one.

On extra units, solid blue or green means better than −65 dBm, orange or green −65 to −78 dBm, solid red weaker, and flashing red disconnected. Colours differ by model.

### Add an access point

As the Arcadyan guides describe it; the WX3400-T0 guide pairs extra units over a cable first, then you move them.

1. Plug the new unit in near the main one and switch it on.
2. Press **WPS** on the main unit, then on the new one, within two minutes.
3. Wait for the light to turn solid blue, then move the new unit to its spot.

If an extra unit stays red, connect it to the modem with a cable until it pairs, then move it back. A Wi-Fi 6 4T4R system takes up to four units, Wi-Fi 6E up to two.

**Kilobat can help.** When your Mac moves to another node or band, Kilobat’s Health says so, so a weaker node isn’t taken for a router problem. See [find a better Wi-Fi spot](https://kilobat.app/guides/recipes/find-better-wifi-spot).

## Guest network

1. Sign in at `https://mymeshdevice.home`.
2. Click **Settings › Guest Network**.
3. Set the guest network name, security type and key, then save.

Guests are kept apart from your own network. Phones on a guest network can’t open the app. Chunghwa Telecom’s walkthrough shows up to three guest networks in the app’s wireless list.

**Kilobat can help.** Kilobat can show a network as a QR code, so guests join with their phone’s camera: [share Wi-Fi with a QR code](https://kilobat.app/guides/recipes/share-wifi-qr-code).

## DNS settings

Chunghwa Telecom documents no DNS setting for the Wi-Fi全屋通 units or the fibre modem. Set DNS on the Mac instead.

**Kilobat can help.** Before you change DNS, [compare resolvers with Kilobat](https://kilobat.app/guides/recipes/pick-faster-dns) to see which answers fastest from your home.

## Connection status and logs

1. Sign in at `https://mymeshdevice.home`; the **Status** page opens first with the network layout and its state.
2. In the app, **網路拓樸** shows whether each access point is online.
3. Check the modem lights; solid green or blue is normal, red means a fault.
4. For a line fault, tap **設定 › 故障報修** (Settings › Report a fault) to report it online.

A red light on the modem, or on the main access point after you have checked its cable, needs Chunghwa Telecom support on `0800-080-123`. The guides describe no event log.

**Kilobat can help.** When the line keeps dropping, Kilobat’s [provider report](https://kilobat.app/docs/health#report) lists outages, latency and speed tests against your plan, ready to send to your provider.

## Questions

**Is user the same as my Wi-Fi password?**

No. `user` is the default admin password for the app and the browser settings. The Wi-Fi key is printed on the label on the back of the access point.

**How do I change the Wi-Fi key on a modem with built-in Wi-Fi?**

Chunghwa Telecom’s guide says to find the modem’s IP address in your network details, open it in a browser and sign in with `user` and `user`. It shows the screens for older modems such as the I-040GW.

**I’ve forgotten my HiNet connection password. Where do I reset it?**

That is the PPPoE account password, not a router password. Reset it at [my.cht.com.tw/HiNetReset](https://my.cht.com.tw/HiNetReset).

## See what your router can’t tell you

Kilobat is a Mac menu-bar app that watches the network from your side: which app is using it, whether the Wi-Fi, the router or the provider is slow, and why a call froze.
