What action can be taken when multiple access points share the same channel, resulting in network slowdown?

When multiple access points share the same channel, it can lead to network congestion and slow performance since they compete for the same bandwidth. Turning down the transmit power can actually help alleviate this issue. By reducing the transmit power, the coverage area of each access point is limited, which can decrease the overlap between them. This can result in fewer devices connected to the same channel at any given time, reducing interference and improving overall network performance.

While increasing transmit power might seem beneficial, it would likely exacerbate the problem by extending the coverage area and increasing channel overlap. Changing the encryption method does not directly influence the channel usage or performance issues caused by multiple access points sharing the same channel. Opting for a wired connection can provide a stable and fast alternative, but it would not resolve the issue of the wireless access points interacting on the same channel.
