WiFi is a good and reliable source of Internet access and is recommended for uninterrupted Internet with good speed. Sometimes you may feel that the speed decreases and that the pages of your web browser load slowly, taking more time.
The download and upload speed is drastically slow and fast at times and places in your home. This just means that your WiFi strength is not the same throughout the house and will be providing different speeds in different places. To find the best point with the good network, you should check the signal strength. Or maybe you just casually want to know how strong your WiFi signal is, then it’s very easy.
For devices like laptops and smartphones etc, there are always signal bars that show the strength of the WiFi signal you are connected to. The lower the number of these bars, the weaker the WiFi signal you are connected to. You can walk around your house while connected to your WiFi and watch the bars decrease as you move away from the router.
This is just a casual way of checking signal strength and does not provide numerical digits or precise information. A more reliable process to check WiFi signal strength is to use apps made for this purpose.
Applications like the wifi analyzer can help you with this job that will allow you to have data on the strength of your WiFi signal. The unit used to check WiFi signal strength is in dBm (decibels relative to a milliwatt) and ranges from -30 to -90 on the scale.
The -30 on the scale shows that your signal strength is perfect and better and this is only possible while you are right next to the network source. The -90 signals that your WiFi signal strength is the weakest possible and you may not even be able to connect at this stage.
The intermediate -50 and -60 are good enough for the job and anything above that will make you feel sluggish while using WiFi.
