This article provides steps to help you troubleshoot your broadband Wi-Fi connection between your device and your modem or router.

1. Ensure your internet is working

  • Check your modem lights
    Solid green, modem is powered on.
    Flashing or solid red, your modem might be faulty. Contact us.
    No light, check your power cable is plugged in properly to the modem and the wall power point. Check the power point is switched ON and works. Try another power point.
  • Internet light:
    Solid green, the internet is working.
    Flashing or off, contact us. 

Check your Vodafone modem device guide for further help with your Vodafone modem lights.

2. Ensure Wi-Fi is enabled on your modem

Check your modem has a Wi-Fi/WLAN solid green light

  • Solid Green = Wi-Fi connection available
  • Green Blinking Slow = Wi-Fi disabled by schedule
  • Green Blinking Fast = synchronisation WPS

3. Turn all your hardware and devices off and on again

  • Power off all your hardware and devices at the wall, such as modems, routers, Fibre ONT, UltraFast HFC cable ONT, switches, hubs and computers.
  • Restart them after a minute, starting with the ONT (if you have Fibre or UltraFast HFC broadband), then followed by your modem, router, then other network devices and then the computer(s).
  • Check you have a green power and internet light on your modem or router.

4. Try getting closer to your modem or router

  • Holding your device, move closer to your modem or router or mesh as there may be Wi-Fi interference or your device may be too far.

Wi-Fi Interference Many things can interfere or weaken your Wi-Fi signal quality and it may impact your connection and speed experience. Keep your modem/router or Wi-Fi devices out of cupboards, patch panels, away from electrical and kitchen appliances such as fridges and microwaves, away from mirrors, baby monitors, cordless phones, hot water cylinders and blue tooth speakers to reduce interference. Look out for internal building materials made from metal, concrete, marble, tiles or brick, as Wi-Fi cannot penetrate these materials. 

5. Optimising your Wi-Fi

Positioning and placement Optimise your Wi-Fi performance by re-positioning your modem/router or mesh following our simple principles of Out, Up and Open.

Out Up Open
  • Out of cupboards
  • Out of packed shelves
  • Out from behind TV's
  • Out from under desks
  • Out of the kitchen
  • Out from far edges of the home
  • High away from obstacles
  • High away from cluttered spaces
  • High for a clear line of sight outward
  • Away from blocking objects
  • Away from electrical appliances
  • Less interference in open air
  • Clearer air for signal to get out
  • If you have Wireless Broadband, we recommend placing your modem near a window and out in the open. Try a few different places around the house to help find the best spot

Check you are on the right Wi-Fi band - 2.4GHz or 5GHz?
Check you're on the best Wi-Fi band for your home environment. The 2.4GHz has a greater reach, while the 5GHz has a stronger signal.  Wi-Fi band steering - some modems/routers/mesh have the ability to automatically steer devices to the best available frequency band when connected to the Wi-Fi network. By turning on band steering, you can get the best performance.   

  • Long range, better obstacle penetration
  • Compatible with all Wi-Fi devices
  • Less capacity and more prone to interference
  • Good for email and browsing. It is ok for streaming as long as there are only 1 or 2 devices connected
  • Suitable for older devices that support only 2.4GHz
  • Slightly shorter range, can't easily penetrate solid objects (example, concrete or steel wall)
  • Not all devices are 5GHz compatible
  • Less congested and higher speed for streaming functions and for using more devices.
  • Good for streaming, online gaming and transferring large files.
  • Best for Fibre and UltraFast HFC broadband customers as 5GHz takes advantage of faster broadband speeds

6. Check your devices

  • Eliminate sources of interference. Cordless phones should sit away from modems and routers as they will interfere with your Wi-Fi signal.
  • Make sure you're connected to your Wi-Fi network 
  • If you have a modem or router as well as a Wi-Fi mesh, extender, or booster, check that your device is connecting to the right one. You may need to turn off the Wi-Fi from your modem or router if this is conflicting with your Wi-Fi mesh, extender or booster.
  • Ensure you have the latest Wi-Fi drivers on your computers, etc.

7. Advanced checks

  • Check your router or access point for MAC address filtering. The person configuring the router or access point may have set it up in such a way that only certain device MAC Addresses (Media Access Control numbers) can connect to the Internet. Some companies use this strategy to prevent unauthorised access to their network. Some parents use this feature as a form of parental control.
  • Try using a different DNS server. You may need to set your DNS server settings manually. There are too many devices and operating systems out there for me to go into detail on how to do this here but Google is your friend.
