What is Packet Loss?
Packet loss refers to the failure of data packets to reach their intended destination over a network. When you send data over the internet, it is broken down into small packets, each containing a portion of the data. These packets are then transmitted over the network, where they are reassembled into the original data. However, due to various reasons, some of these packets may not reach their destination, resulting in packet loss.
Causes of Packet Loss
Packet loss can occur due to a variety of reasons, including:
Network congestion, where too many devices are competing for bandwidth, causing packets to be dropped.
Interference from other wireless devices, such as cordless phones, microwaves, and neighboring WiFi networks.
Physical barriers, like walls and floors, that can weaken the WiFi signal, leading to packet loss.
Distance from the WiFi router, as the signal strength decreases with increasing distance.
Hardware or software issues with the WiFi router, modem, or network interface card.
