![]() ![]() Although some of these function perfectly well, many are poorly designed or have poor quality components that do not function as advertised. Recently, there has been a flood on the market of cheap and generic wireless keyboards and mice. Moreover, this issue can also be caused when there are many USB devices connected to the same laptop, and thus the voltage has to be split between all of them. This is because the battery will try to conserve energy and thus not provide high power to the USB ports. This drop-in power is a frequent problem experienced in laptops. However, if there is a drop in power in the USB port, this can reduce your dongle’s performance and range. Usually, these dongles rely on the USB port for power to operate and receive signals. Low PowerĪlthough your wireless keyboard or mouse has its own batteries that supply its power, the same is not true for the USB dongle that is connected to your PC or Laptop. Having any of these nearby when you are trying to use a wireless device can cause interference and thus reduce range. These can include common objects like phones or tablets to larger appliances like microwaves and fridges. Often, there can be many sources of interference within one’s workspace. This causes a loss of information, and thus, the signal from your device is not received by the dongle clearly. Just like waves on a lake, radio waves can also hit or ‘interfere’ with one another. One of the most common reasons behind the reduced range is interference. ![]() It turns out that a few different factors can cause the reduced range commonly reported by many users. After all, the range may not even be long enough for you to move away from your desk! ![]() This is a significant problem and can ruin the experience of using a wireless device. In fact, for most people, their wireless device stops functioning properly as soon as it is more than a few feet away from the PC. Why does my Wireless Keyboard or Mouse have low range?Īlthough many wireless devices on the market are advertised as having a 30-foot range, this rarely turns out to be the case. However, now that we have understood the functioning of these devices, a few questions also arise. Thus, in this way, you are able to control your PC wirelessly from the other side of the room. This signal is received by the dongle and passed along to the computer. The wireless dongle that you plug into your PC acts a lot like an antenna or radio receiver on a satellite TV dish.įor example, whenever you strike a key on your wireless keyboard, the keyboard sends out a radio signal with information about which key has been pressed. Instead, the task can be done from a bed, couch, or anywhere else you please.Īll this may bring to mind a question, how do these wireless keyboards and mice even work?Įssentially, wireless devices make use of radio frequencies for communication between the computer and the device. Nowadays, there is no need to be tethered to your desk in order to operate your Laptop or PC. These useful inventions have made cables and cords littering your workspace a problem of the past. ![]() Wireless gadgets have recently brought about a revolution in electronic devices.
