A repeater can also have some limitations and drawbacks, especially if you have a large or busy network. One of the main disadvantages of a repeater is its impact on the network speed and performance. A repeater cuts the bandwidth in half, as it uses the same channel to receive and transmit the data. This can cause delays and drops in the signal quality, especially if you have multiple devices connected to the network. Another drawback of a repeater is its vulnerability to interference and obstructions. A repeater depends on the signal strength of the router or access point, and any walls, furniture, or appliances that block the signal can reduce its effectiveness. Furthermore, a repeater can also pose some security risks, as it may expose your network to unauthorized access or attacks.
