3. Setup
Follow these steps to set up your ARRIS SURFboard SBR-AC1750 WiFi Router.
- Position the Router: Place the router in a central location in your home, away from obstructions and sources of interference like cordless phones or microwaves.
- Connect to Modem:
- Ensure your modem is powered off.
- Connect one end of the supplied Ethernet cable to the WAN port (blue) on the back of the SBR-AC1750 router.
- Connect the other end of the Ethernet cable to an Ethernet port on your modem.
- Power On Modem: Power on your modem and wait for it to fully initialize (typically indicated by stable status lights).
- Power On Router: Connect the power cord to the Power Input on the back of the SBR-AC1750 router and then plug it into a power outlet. The Power LED on the front panel should illuminate.
- Wait for Initialization: Allow a few minutes for the router to power on and establish an internet connection. The WAN, 2.4G, and 5G LEDs should become solid, indicating readiness.
- Connect a Device:
- Wired Connection: Connect an Ethernet cable from your computer to one of the yellow Ethernet Ports (1-4) on the router.
- Wireless Connection: On your Wi-Fi enabled device, search for available Wi-Fi networks. Select the network name (SSID) printed on the label on the bottom or back of your router and enter the Wi-Fi password (security key) when prompted.
- Access Router Interface: Open a web browser and enter the default IP address (usually
192.168.0.1or192.168.1.1) into the address bar. Log in using the default username and password (typically found on the router label or in the Quick Start Guide) to configure advanced settings.
The SBR-AC1750 is compatible with any cable, DSL, or fiber modem.
4. Operating the Router
Connecting Devices
- Wireless Devices:
To connect a device wirelessly, enable Wi-Fi on your device and select the appropriate network name (SSID) from the list of available networks. Enter the Wi-Fi password when prompted. The SBR-AC1750 broadcasts two Wi-Fi networks: one on the 2.4 GHz band and one on the 5 GHz band. The 2.4 GHz band offers wider coverage, while the 5 GHz band provides faster speeds over shorter distances.
- Wired Devices:
For devices requiring a stable, high-speed connection, use an Ethernet cable to connect them to any of the four Gigabit Ethernet ports (1-4) on the rear of the router.
Using Wi-Fi Protected Setup (WPS)
WPS allows you to connect compatible wireless devices to your network without manually entering the Wi-Fi password.
- Press the WPS button on the front panel of the SBR-AC1750 router. The WPS LED will start blinking.
- Within two minutes, press the WPS button on your wireless device.
- The device should automatically connect to your Wi-Fi network. The WPS LED on the router will become solid for a short period, then turn off.
USB Port Functionality
The USB 2.0 port on the rear of the router can be used to connect external storage devices, allowing you to share files across your network. Refer to the router's web interface for configuration options related to USB storage.
5. Maintenance
Firmware Updates
Keeping your router's firmware updated is important for security and performance. Check the ARRIS support website for the latest firmware versions for your SBR-AC1750 router and follow the provided instructions for updating. Firmware updates are typically performed through the router's web management interface.
Factory Reset
A factory reset restores all router settings to their original default values. This can be useful for troubleshooting persistent issues or when preparing to reconfigure the router.
- With the router powered on, locate the small Reset button on the rear panel.
- Using a paperclip or a similar pointed object, press and hold the Reset button for approximately 10-15 seconds.
- Release the button. The router will reboot, and all settings will be restored to factory defaults. You will need to reconfigure your network settings after a factory reset.
6. Troubleshooting
This section addresses common issues you might encounter with your ARRIS SURFboard SBR-AC1750 WiFi Router.
No Internet Connection
- Check Cables: Ensure all Ethernet cables are securely connected to the router and modem. Verify the WAN cable is connected to the blue WAN port.
- Check Modem Status: Confirm your modem is working correctly and has an active internet connection. Check its status lights.
- Reboot Devices: Power off both your modem and router. Wait 30 seconds, then power on the modem first. Once the modem is fully initialized, power on the router.
- ISP Issue: If the issue persists, contact your Internet Service Provider (ISP) to confirm there are no service outages in your area.
Slow Wi-Fi Speeds or Dropped Connections
- Router Placement: Ensure the router is centrally located and not obstructed by large objects or walls.
- Interference: Keep the router away from other electronic devices that might cause interference (e.g., microwaves, cordless phones, Bluetooth devices).
- Band Selection: For devices closer to the router, try connecting to the 5 GHz Wi-Fi band for potentially faster speeds. For devices further away, the 2.4 GHz band might offer better range.
- Firmware: Ensure your router's firmware is up to date.
- ISP Bandwidth: Verify that your internet plan provides sufficient bandwidth for your usage. High network traffic or multiple simultaneous downloads can affect perceived speed.
- ISP Connection Stability: Intermittent connection drops can sometimes be related to your Internet Service Provider's connection quality. Contact your ISP to have them check the upstream and downstream connections to your service.
Cannot Access Router Web Interface
- IP Address: Ensure you are using the correct IP address (e.g.,
192.168.0.1or192.168.1.1). - Wired Connection: Try accessing the interface from a computer connected directly to the router via an Ethernet cable.
- Browser: Try a different web browser.
- Factory Reset: If all else fails, perform a factory reset (see Section 5) and try accessing the interface with default credentials.
