You manage it in a browser at `http://192.168.0.1`; the My Optus app covers speed tests and help. Optus Ultra WiFi Modem Sign in `192.168.0.1` App My Optus app (iOS and Android) Password The modem password is printed on the label on the bottom of the modem. The Wi-Fi name and password are on the same label and on the Quick connect magnet in the box. Models Optus Ultra WiFi Modem (Gen 2), Optus Ultra WiFi Booster (Gen 2) **Checked 1 November 2026.** Optus Ultra WiFi Modem (Gen 2) and Ultra WiFi Booster (Gen 2), menus as shown in Optus’s device guides in 2026. The Optus Ultra WiFi 5G Modem and older Sagemcom modems have different menus. ## Sign in to the Optus Ultra WiFi Modem 1. Connect your Mac to the modem’s Wi-Fi, or plug it into a yellow **LAN** port. 2. Open `http://192.168.0.1` in your browser. 3. Click **Enter password** and type the password from the bottom of the modem. 4. Click **Login**. The menu has **Home**, **My Wi-Fi**, **Connected Devices**, **Settings**, **Restart**, **Help** and **4G Status info**. Optus documents no password recovery; a factory reset erases all your settings. ## Restart it properly It may take several minutes for the modem to reconnect after a restart. 1. Press **On/Off** on the back to turn the modem off. 2. Unplug the power supply and wait 30 seconds. 3. Plug the power supply back in. 4. Press **On/Off** to turn the modem on. ### From the settings menu 1. Sign in at `http://192.168.0.1`. 2. Click **Restart**; Optus says this menu restarts the modem. ### Factory reset 1. To keep a copy of your settings, click **Settings**, then **Continue** below **Modem Settings**. 2. Click **Maintenance › Backup & Restore › Create Backup file**. 3. Click **Restart**, then **Factory reset modem** twice. 4. Click **Continue** and wait. Without the menu, hold a paper clip in the **Reset** hole for at least 10 seconds. A reset erases your Wi-Fi name, password and port forwards. ### Schedule a restart Optus documents no scheduled restart for this modem. **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 Optus’s guides for the Ultra WiFi Modem (Gen 2) describe no firmware update page or check. Its LED guide lists no update light either. ## See connected devices 1. Sign in at `http://192.168.0.1`. 2. Click **Connected Devices** to see the list of devices on the modem. Optus’s guides don’t describe pausing or blocking a single device from this menu. If strangers are on your Wi-Fi, change the Wi-Fi password under **My Wi-Fi**. ### Block websites 1. Click **Settings**, then **Continue** below **Network Settings**. 2. Click **URL Filter**, then **Add Address**. 3. Type the website address without `http://` or `https://`. 4. Click **Apply**. **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 Optus’s guides for this modem don’t mention UPnP or NAT-PMP, so there is no documented switch for either. Port forwarding is documented. The modem has a built-in firewall. Each forwarded port lets the internet reach that device directly, so forward only what a game or app needs and remove rules you no longer use. ### Port forwarding You need the IP address of the computer or console you forward to. 1. Click **Settings**, then **Continue** below **Network Settings**. 2. Click **Port forwarding** and type a **Custom service name**. 3. Choose a **Service**, or **Other** if unsure, and a **Protocol** such as **TCP - UDP**. 4. Leave **External Host** empty and enter the **External Port**, such as `6000-6100`. 5. Enter the device’s address as **Internal Host** and the same ports as **Internal Port**. 6. Click **Add** to save the rule. **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 Optus lists QoS (Quality of Service) as not supported on this modem. For speed and reliability, Optus suggests connecting devices to the yellow **LAN** ports with the supplied cable. **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 modem is dual band, 2.4 and 5 GHz Wi-Fi 6. A green **Wi-Fi** light means it switches devices between the bands automatically; blue means it doesn’t. 1. Sign in and click **My Wi-Fi**. 2. Click the field next to **Wi-Fi Name (SSID)** below the network you want to rename. 3. Type the new name and click **Apply**. 4. Reconnect your devices with the new details. Optus’s guides don’t say how to give each band its own name. ### Change the channel 1. Sign in and click **My Wi-Fi**. 2. Choose a channel from the **Channel Selection** list. 3. Click **Apply**. Optus suggests a new channel when the connection is intermittent. **Kilobat can help.** Kilobat shows which band and channel your Mac is on, and `kilobat channels` suggests the least crowded channel.

Optus says nearby devices can use the booster automatically; the device decides when to roam. 1. Plug the booster in next to the modem and make sure its **On/Off** button is pushed in. 2. When the **Mesh** light flashes red, connect the booster to a yellow **LAN** port with an Ethernet cable. 3. When the **Mesh** light turns solid green, it has paired; unplug the cable. 4. Move the booster halfway between the modem and the weak spot, off the floor. A red **Mesh** light means the booster is too far away. If it still won’t connect, hold its **Reset** button with a pin until the **Power** light turns red, then pair it again. **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 Optus’s guides for this modem don’t describe a guest Wi-Fi network. **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 Optus documents no way to change the DNS servers on this 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 and click **Home** to see the modem information. 2. Click **Settings**, then **Continue** below **Modem Settings**, to see the internet connection information. 3. Check the **Internet** light; solid green means connected and solid red means a connection error. 4. Solid blue means the modem is using its 4G backup SIM, not the nbn. Optus says 4G backup isn’t meant as a stand-alone service. If the light stays blue, check the modem’s cables or check your connection in the My Optus app. Under **4G Status info**, the backup’s **Data APN** is `LTEBROADBAND`. **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. ## Manuals and downloads - [Optus device guides: OPTUS Ultra Wi-Fi Gen 2](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10) - [Optus Ultra WiFi Modem (Gen 2) quick start guide (PDF)](https://www.optus.com.au/content/dam/optus/documents/for-you/support/nbn/optus-ultra-wifi-gen2-modem-quick-start-guide.pdf) - [Optus Ultra WiFi Booster (Gen 2) quick start guide (PDF)](https://www.optus.com.au/content/dam/optus/images/for-you/support/Optus_Ultra_WiFi_(Gen_2)_Booster_Quick_Start_Guide_Optus.pdf) Links go to the maker’s own pages. ## Questions **Where is the Optus modem password?** On the label on the bottom of the modem, next to the Wi-Fi name and password. The Quick connect magnet also has the Wi-Fi details. **Why is the Internet light blue?** The modem is using its 4G backup because the nbn connection is down. Check the cable to the nbn equipment and the My Optus app. ## Sources - [Optus device guides: Establish a connection to the modem settings menu (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/connectivity/establish-a-connection-to-the-modem-settings-menu) - [Optus device guides: Guide to the modem settings menu (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/first-use/guide-to-the-modem-settings-menu) - [Optus device guides: Restart your modem (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/settings/restart-your-modem) - [Optus device guides: Restore factory default settings (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/settings/restore-factory-default-settings) - [Optus device guides: Set up port forwarding (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/settings/set-up-port-forwarding) - [Optus device guides: Change Wi-Fi Hotspot channel (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/settings/change-wi-fi-hotspot-channel) - [Optus device guides: Guide to the modem LEDs (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/first-use/guide-to-the-modem-leds) - [Optus device guides: Block websites (Ultra Wi-Fi Gen 2)](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/settings/block-websites) - [Optus device guides: Ultra Wi-Fi Gen 2 specifications](https://devicehelp.optus.com.au/optus/ultra-wi-fi-gen-2-windows-10/specifications) - [Optus Ultra WiFi Modem (Gen 2) quick start guide (PDF)](https://www.optus.com.au/content/dam/optus/documents/for-you/support/nbn/optus-ultra-wifi-gen2-modem-quick-start-guide.pdf) - [Optus Ultra WiFi Booster (Gen 2) quick start guide (PDF)](https://www.optus.com.au/content/dam/optus/images/for-you/support/Optus_Ultra_WiFi_(Gen_2)_Booster_Quick_Start_Guide_Optus.pdf) Checked on 1 November 2026. ## 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.
