What are the common causes of intermittent Wi-Fi connectivity?
Intermittent Wi-Fi connectivity can be caused by a variety of factors, including physical barriers, network congestion, and outdated router firmware. Physical barriers such as walls, floors, and ceilings can block or weaken the Wi-Fi signal, leading to dropped connections. Network congestion, on the other hand, occurs when too many devices are connected to the same network, causing the router to become overwhelmed and drop connections.
In addition to physical barriers and network congestion, outdated router firmware can also cause intermittent connectivity issues. Router firmware is the software that controls the router’s functionality, and if it becomes outdated, it can cause compatibility issues with devices and lead to dropped connections. Regularly updating the router firmware can help to resolve these issues and ensure a stable connection.
