To improve signal range and coverage, try relocating your WiFi router to a more centralized location within your home or office. Avoid placing it near obstacles or electronic devices that may interfere with the signal. In some cases, adding WiFi range extenders or repeaters can help boost the signal strength and expand coverage to areas with weak signals.
Furthermore, upgrading to a WiFi router with better range and more advanced features, such as multiple antennas or beamforming technology, can significantly enhance your network’s coverage and reduce random WiFi shutdowns.
Overloading The WiFi Network
Overloading the WiFi network is a common cause of random WiFi shutdowns. When there are too many devices connected to the network and attempting to access the internet simultaneously, it can put a strain on the router and cause it to shut down.
This issue typically occurs in busy households or office environments where numerous devices such as smartphones, laptops, tablets, gaming consoles, and smart home devices are connected to the same WiFi network. Each device requires bandwidth to function properly, and when the demand exceeds the router’s capacity, it can lead to a network crash.
To prevent overloading, it is essential to manage and prioritize network traffic. One solution is to limit the number of devices connected to the WiFi network or invest in a router with higher capacity. Additionally, implementing Quality of Service (QoS) settings on the router can help prioritize critical tasks such as streaming or gaming over less important activities like file downloads.
Regularly monitoring the network and updating the router’s firmware can also improve its performance and stability. By addressing the issue of overloading, users can enjoy uninterrupted WiFi connectivity and minimize the chances of random WiFi shutdowns.
