Wi-Fi Coverage Expectations

Wi-Fi Coverage is affected by many factors in and around your property as well as the devices you are using, such as phones and laptops. Your wireless devices connect to the router using WiFi, the router in turn connects to the internet via our network. These are two separate systems, although a problem with either will result in the user experiencing a degraded connection, buffering, drop-outs, high latency and slow speeds. Beacon Broadband are not responsible for WiFi at your property, although we are always willing and able to help out.

Here are a few key factors that may help you to get the best from your wireless network:

 

1. Location of Router. Your wireless router transmits and receives information from your wireless devices. Ideally this should be located as near as reasonably possible to the areas in your property where you need Wi-Fi the most. Devices that use media streaming such as Smart TVs tend to be most sensitive to a strong signal.

 

2. Walls and property size. The strength of wireless signals reduce with distance, but is also affected by absorption or reflection in walls. Sometimes this is easy to see, if the property has thick stone  walls, but some types of modern insulated plasterboard, bison slab floors or double-glazed windows can also have a significant effect on the wireless signal. If your Wi-Fi network uses the faster 5GHz band (instead or as well as the 2.4GHz band) the effect of walls and distance is far greater. It is generally advised to use the 5GHz band within the same room as the router, as it may not work effectively through walls. We also advise using firesticks and wireless printers on 5Ghz and using mobile phones, tablets and laptops on 2.4Ghz.

 

3. Type and location of wireless devices. Wi-Fi works across thousands of different types of devices, but they all follow industry standards for communication and security. Where multiple wireless devices are connected to the same router, such as TVs, laptops, and smartphones, they have to communicate with each other to ensure that they all get a share of the Wi-Fi capacity. By communicating between themselves, Wi-Fi devices can ‘agree’ whose turn it is to send or receive data from the internet. In some cases, not all Wi-Fi devices can talk to each other, for example where there is a laptop at one end of a property, a router in the middle and smartphone at the other end. In this case, both devices can communicate with the router, but they may not see each other and therefore cannot agree whose turn it is to access the router. This scenario can have a negative effect on all the devices in the network. Equally, if one wireless device has a very poor signal, but all others are good, the router will spend a disproportionate time re-sending information to the weakest device, reducing the capacity for all others.

 

4. Channel number and Channel Width. Generally, wide channels (40MHz) or higher have the highest data capacity and therefore can send or receive data faster. However, wide channels are also more likely to overlap with other wireless routers if nearby, which creates interference that reduces  speeds. Sometimes a narrow channel (20MHz) can therefore give faster real-world performance.

 

5. Security and data encryption. Always ensure that your Wi-Fi network has encryption enabled. The  best levels of encryption are based on standards known as WPA. It is not generally advised to use the older WEP encryption method. Please note that some very old wireless devices do not support WPA.

 

6. Interference from other sources. Some non Wi-Fi equipment is permitted to transmit data on the 2.4GHz Wi-Fi band and can cause interference or reduced performance on your Wi-Fi network. This equipment can include baby monitors, DECT cordless phones, X-Box controllers, some alarm and door entry systems, Magic Eye media transmitters, microwave ovens and Zigbee remote controllers (used by some smart lighting and audio visual systems). It is generally recommended to locate your router and wireless devices as far as possible from this type of equipment.

 

7. Device Compatibility. Most Wi-Fi routers use up to date standards (protocols) to communicate with their associated Wi-Fi devices. However, some old equipment may not be compatible with the latest standards. For example, older equipment used the 802.11 A, B and G protocols, whereas newer equipment is built to use 802.11 N and AC protocols. If you find that older devices cannot connect to your wireless network, please consider replacing this equipment with newer units, or change the protocol standards on your router.

 

8. Using wireless extenders and repeaters. Boosting wireless coverage can be achieved by using specialised equipment to add repeaters or extenders. Whilst these can be an effective means of improving coverage, it is vital that they are set up correctly or they can cause lower speeds and reduce reliability. We strongly advise asking for professional help in selecting and configuring extenders and repeaters. Please contact us for more information.

 

9. Expected speeds. Many routers claim speeds of 150Mbps, 300Mbps or higher data rates. These are theoretical maxima based on controlled laboratory environments. Real world speeds are generally less than 50% of these headline speeds. Please keep in mind that the speed of internet access is limited to the speed of your line or subscription package, which will often be different than the Wi-Fi speed. As an example, if you have a 30Mbps internet subscription, you will not be able to download data from the internet faster than this. Please also note that your internet connection speed is shared between the users and devices connected to your network. Therefore, if say a Playstation game is being updated at the same time as an Apple update and a movie download, they will all share the overall internet capacity at the property and will therefore appear slower than the headline subscription speed.

10. If experiencing connection issues, we recommend using www.nperf.com or the nperf app in order test your speed. Please send a screenshot of your results to support@beaconbroadband.co.uk including the date/ time and WiFi icon. Also please ensure you have at least 50% charge on your battery with bluetooth disabled, if using a wireless device. Ideally use a PC or Laptop with a direct connection via a network/ ethernet cable to the router. This rules out WiFi by testing the actual connection to our network and internet, giving a more accurate result. It is very important that all other WiFi and internet devices (including extenders, tv's, consoles etc) are powered off during the test as these may cause interference or take up some of your available bandwitdth, both of which will give an inaccurate test result.
