If WiFi coverage is not good, should I use a wireless repeater or a powerline modem?

Poor WiFi signal is a headache for many friends now. How to better expand the network? Undoubtedly, planning WiFi during decoration is the best solution. So how to make WiFi signal better without modifying the existing wiring? Wireless mesh solution is certainly the best, but its equipment price is two to three thousand yuan, which is really unaffordable. Simple and affordable wireless repeater and powerline cat are solutions that home users can consider.

Functionally, the powerline cat obtains the network signal through the wires, while the wireless repeater transmits the original wireless signal through its own forwarding, thereby expanding the coverage of the wireless network. The method of use is also very simple. We deploy the wireless repeater on the socket at the edge of the wireless router signal coverage, and then simply set it up, so that the wireless repeater can extend the wireless network to the room that needs to be covered. Currently, the operation of wireless repeaters on the market is becoming easier and easier. Most products can realize the automatic pairing function with the wireless router, without the need for manual operation and configuration by the user.

Simply put, a powerline cat is a device that converts the wires hidden inside the walls of a home into network cables and expands the network. Powerline cats are now divided into two types: "wired powerline cats" and "wireless powerline cats". "Wired powerline cats" are computers, TVs and other devices that need to access the Internet, which require network cables to connect to the powerline cat to access the Internet. "Wireless powerline cats" are developed based on "wired powerline cats". After deployment, users can not only use network cables to connect to the Internet, but it can also provide users with wireless network coverage, making it convenient for mobile devices such as smartphones and tablets to access the Internet.

However, network expansion through wireless repeaters will halve the network transmission rate. Deploying one can still meet user needs. If you want to deploy multiple, it is very likely that the network speed will not be able to perform normal network behavior. The network transmission rate of powerline cats is currently 1Gbps. Deploying multiple can also achieve smooth transmission. However, powerline cats are relatively expensive and must be used in pairs. If the quality of the wires in your home is not good, the network transmission rate will drop significantly. Powerline cats and wireless repeaters, which one is more suitable for you?
