GFiber router restart, UPnP, port forwarding and custom DNS

Sign in to the GFiber router

1. Install the gFiber app and sign in with your GFiber email and password.

2. The app finds your service and opens your network dashboard.

3. To see the Wi-Fi password, tap Network, scroll down and tap Show Password.

4. To change it, tap Network › Network settings › Primary network settings, edit it and tap Save.

In the web portal, sign in, click Network and use Show password or Edit network settings. GFiber support can’t see or change your Wi-Fi password for you.

Restart it properly

1. In the gFiber app, tap Network, then Router details.

2. Tap Restart router, then Confirm.

3. Wait up to 5 minutes until the status light is solid green (Wi-Fi 7 and 6E) or solid blue (Wi-Fi 6 and Multi-Gig).

A restart keeps your Wi-Fi name, password and settings. Reset Router Settings in the app restores IP addresses, DNS and port forwarding to defaults but keeps the Wi-Fi name. Holding the reset button for 10 seconds erases everything.

Restart by hand

1. Unplug the power cable from the back of the router.

2. Wait at least 10 seconds, then plug it back in.

3. Wait 3 to 5 minutes for the light to turn solid.

If the internet stays down after a power cut, also restart the Fiber Jack: unplug it, wait 30 seconds and reconnect it. Never disconnect the glass fibre line at the wall plate.

Schedule a restart

GFiber documents no scheduled restart.

Update the firmware

GFiber routers update their software automatically. GFiber mentions this mainly for mesh setup: the router may install an update before it pairs an extender.

1. Leave the router plugged in and online.

2. If an update is running, follow its progress in the Home tab of the gFiber app.

3. Wait for it to finish before you pair an extender or restart the router.

GFiber’s help offers no way to check the firmware version or install an update yourself.

See connected devices

1. In the gFiber app, tap Network, scroll to Connected devices and tap Manage devices.

2. Tap a device and scroll to Connection details.

3. Check the connection type, signal strength (RSSI), band, IP addresses and which router or extender it uses.

4. To group devices, tap + on the Manage devices screen, name the group and tick its devices.

Pausing, blocking and schedules work only with the Wi-Fi 6E and Wi-Fi 7 routers. GFiber suggests turning off private Wi-Fi addresses on your own devices so the app recognises them.

UPnP and port forwarding

GFiber routers support UPnP, which lets consoles and apps open the ports they need. GFiber’s help doesn’t say whether it is on by default.

1. In the gFiber app, tap Network.

2. Tap Network settings › Advanced network settings › Ports.

3. Find Universal plug and play and turn it on.

4. Tap Save.

GFiber points out that port forwarding changes your network’s security baseline. With UPnP on, any app or device on your network, including malware, can open ports itself. Delete rules for games and servers you no longer use.

Port forwarding

1. On the same Ports screen, tap Add a new rule.

2. Pick the Device, a Service or Custom, the Protocol and the Port Range.

3. Tap Save, then Confirm.

4. To delete a rule later, tap it, then Remove rule.

NAT-PMP

GFiber’s help doesn’t mention NAT-PMP.

Prioritise calls and gaming

GFiber documents no QoS or device priority setting for its routers.

2.4 and 5 GHz, and the channel

GFiber recommends one name for all bands so devices can roam. Splitting helps older 2.4 GHz smart home devices connect.

1. In the gFiber app, tap Network › Network settings › Advanced network settings › Wi-Fi.

2. Turn on Use a unique SSID per band.

3. Enter a name for 2.4, 5 and 6 GHz; names are 1 to 32 characters.

4. Tap Save. Devices disconnect briefly.

All bands keep the same password when split. GFiber suggests keeping 5 and 6 GHz under one name and giving only 2.4 GHz its own.

Change the channel

Current gFiber routers choose channels automatically. GFiber says manual channels exist only on the retired Network Box.

Mesh: which node a device uses

The gFiber Wi-Fi 7 Mesh Extender pairs with the Wi-Fi 7 Router over WPS.

1. Place the extender within 5 feet of the router and turn it on; the light turns solid white.

2. Press the WPS button on the router, then on the bottom of the extender.

3. Wait for the extender light to turn solid green.

4. Unplug it, move it halfway to where you need coverage and turn it back on.

At its new spot, solid green means a good connection; red means move it closer. Device details in the app show which router or extender each device uses.

Guest network

The guest network is a separate, isolated Wi-Fi network on the Wi-Fi 6, Multi-Gig, Wi-Fi 6E and Wi-Fi 7 routers.

1. In the gFiber app, tap Network.

2. Under Guest network, tap Manage.

3. Turn the guest network on.

4. Give it a name different from your main network, set a password and tap Save.

To share it later, tap Show password under Guest network.

DNS settings

1. In the gFiber app, tap Network › Network settings › Advanced network settings › DNS.

2. Turn DNS servers on.

3. Enter up to 3 IPv4 DNS server addresses in order of preference.

4. Tap Save.

In the web portal it is Network › Edit network › Advanced network settings › Edit › DNS, then Use custom DNS servers. Dynamic DNS is set on the same screen, in the app only.

Connection status and logs

1. Open the gFiber app and look at Network for your connection status and outage alerts.

2. Without the app, enter your address at gfiber.com/outage/check.

3. On supported routers, run Network Health from the app’s home screen and tap Show details for a score and tips.

4. To get outage texts, text START to 434237.

A solid red light on the Wi-Fi 7 Router means no internet connection. GFiber’s help describes no event or system log.
