Network congestion is a common local issue that can lead to a slow internet connection. This occurs when there is too much data being transmitted over the network, surpassing its capacity to handle it effectively. This congestion can be caused by multiple devices or users accessing the internet simultaneously, particularly if they are engaging in bandwidth-intensive activities such as streaming video, online gaming, or large file downloads. As more devices connect and usage increases, the available bandwidth for each device decreases, leading to slower connection speeds and increased latency.

While router misconfiguration, malware infection, and physical hardware damage can also affect internet speeds, they are typically less common or specific problems compared to the widespread possibility of network congestion. These issues may cause inconsistent performance or outright disconnections, but network congestion tends to be more prevalent in environments where many users or devices are competing for bandwidth access.
