![]() ![]() Some cases contain metal that can affect the signal. Remove the case from your device and see if the connection improves.However, your phone or mobile device has some unique features and challenges. Much of the advice on this page is relevant to both Mobile Devices and laptop or desktop computers. Wi-Fi link speed is faster thanWi-Fi throughput which is faster than your internet. Link speed will always be higher than Wi-Fi throughput. Wi-Fi link speed shows the maximum theoretical speed between your device and your local Wi-Fi router given the distance to your router, signal strength, Wi-Fi technology standard (2.4 / 5 GHz), frequency and congestion. Wi-Fi throughput will be higher than your internet speed. Wi-Fi throughput shows the maximum measured transfer speed between your device and your local Wi-Fi router using the UDP protocol. Changing one device to 5 GHz will also improve the performance of other devices still using 2.4 GHs because there will be reduced congestion. If you are near to the router or an extender then you will see an improvement. So, should you change to 5GHz? If you have the option to change then you should try. This is because there are many devices that use 2.4 GHz such as baby monitors, Bluetooth, remote controls and most Wi-Fi devices default to 2.4 GHz. Congestion is where there are many devices using the same frequency and this causes interference and poorer performance. In the table we show that 2.4 GHz has high congestion and 5 GHz is low. These drawbacks can be resolved by installing Wi-Fi repeaters or extenders but at extra cost. Unfortunately it is not so simple! 5 GHz is faster but has a smaller range than 2.4Ghz and doesn't penetrate walls, floors and ceilings as well as 2.4GHz. 5 GHz supports speeds of up to 1300 Mb/s more than twice the maximum of 2.4 GHz. Your Wi-Fi router will support 2.4 GHz, 5 GHz or both and this can make a difference to the speed of your connection. You can have an excellent signal strength and still struggle to stream HD Video if your connection is poor. Difference Between Signal Strength and Speedīeing able to stream video content is not only dependent on a strong steady signal but also on the speed of your Wifi and Internet connection. It is because we are dealing in such small numbers that the dBm figures are negative. The Power nW column shows the equivalent power in nW (1 nanowatt = 0.000001 milliwatt) to show how the strength rapidly changes as you move up and down the dBm scale. In this case we are measuring power in milliwatts - dBm. The unit dBm is a decibel-milliwatt and is an indication of power but the decibel scale is logarithmic meaning that a change of 10 (from say -60 to -70 is actually a change of 10 times). 30 dBm) which is a little confusing so here is what is going on. The numbers used in the previous table are all negative (e.g. The quality of the video will be dependent on the download speed of your connection. With a signal strength greater than -60 dBm you should be able to stream normal video and even HD video. At low signal strength (below -70dBm and weaker) you will be unlikely to do more than send or receive emails and maybe not even that. The stronger the signal the more you will be able to do. This table shows how signal strength impacts the Quality of Experience you can expect from your device. You may be paying for very fast internet but if you are not getting a strong signal then you will not be getting what you paid for. The quality of the signal you receive on your device has a great impact on the Quality of Experience you will enjoy from your Internet connection. Speedup Wireless Connection by Using a Better Aerial.Check that Your Wi-Fi is Not Being Used by Other People.Problem with Interference from Other Users.On this page we will help you to understand more about the Wi-Fi signal quality and how it can impact your Internet speed as well as providing other tips to get the most out of your connection.ĭifference Between Signal Strength and Speed If you find that your connection is faster on wire than on wireless then you have a problem that you should be able to fix without switching broadband provider or buying more equipment. If you are connecting to the Internet using Wi-Fi then you can check if your Wi-Fi can be improved by connecting your PC to the router by a network cable and run the speed test. They may be unaware that wireless connections are much less reliable than wired connections and slow internet connections may be caused by a problem at home rather than with the ISP service. Today many people use wireless routers at home for convenient access to the internet without running cables all over the house. ![]()
