Positioning 4G Assure to get the best signal

It's vital that you put your hub and 4G Assure dongle in the right place to get the best 4G connection. 

Put your 4G Assure dongle close to a window

Walls and structures can affect mobile reception – so having the shortest distance between the 4G Assure dongle and the outside world will give you the best 4G connection at your workplace.

Keep the 4G Assure dongle clear

Don’t put anything on top or closely around the 4G Assure dongle and definitely don’t shut it in a cupboard, it could affect your 4G signal.

Only use the cable that comes with 4G Assure

Swapping the cable supplied with a longer one can cause issues powering the 4G Assure dongle, which will impact your experience. We recommend you only use the cable we provide – but stretching it as close to a window as you can should give a better performance.

Conditions you can’t control

The weather, the environment and how many people are using the network can also affect 4G reception. These are things you can’t change of course – but you can check your signal strength to see how you’ll be affected.

How to check your 4G signal

Signal strength is really important to 4G Assure. You’ll need a good 4G signal to stay connected if broadband isn’t working.

It’s quick and easy to check your 4G signal in your Hub Manager:

  1. Open a web browser and type http://btbusinesshub.home/resilience into the search bar.
  2. If prompted, enter your admin password (it’s on the back of your hub).
  3. You’ll instantly see a screen showing your 4G signal strength. We’ve given you an example of the BT Business Hub 5 screen below.
  4. Check the mobile signal level. If it’s weak (one bar or below), try moving the dongle and docking station to a new position to improve the signal strength. It’s best near a window. Your signal will automatically update on the Hub Manager.

Your mobile signal will be shown in bars. One bar is the weakest and five bars is the strongest. 4G Assure needs at least two bars to get the best experience.
