WiFi range extenders and mesh
Access points create new WiFi coverage zones in a home using Ethernet cabling. WiFi range extenders (repeaters) rebroadcast the existing signal but are limited by router distance, allow only one or two chained units, and often suffer from latency or dropouts. Many devices can operate as either an access point or a WiFi extender, depending on the selected mode. Prices are from $26.
Mesh systems are essentially WiFi extenders with added features such as automatic roaming, unified SSID, and better load balancing. Prices from a $200
WiFi over power adapters
Over-power adapters extend ethernet from the router to other rooms using power lines; no cables are required. Prices are from $60 for a pair.
Home WiFi routers and mesh
Basic routers and modems in one are suitable for home or office internet. They provide a WiFi reception area within a house, typically within 15 metres radius on open space with up to 20 WiFi simultaneously connected devices. Prices are from $30.
Commercial WiFi access points and mesh
WiFi and mesh networks with several access points are good for office or public WiFi installations, house-wide WiFi and where 100+ WiFi users are connected at once. Mesh WiFi systems usually provide additional management, monetization and security features. However, a pure wireless WiFi mesh may not be effective in big houses with concrete walls and ethernet cabling required. Prices are from $130 per device.
Network switches
Network switches extend the number of Ethernet ports available from the router. PoE switches provide power to WiFi access points. Prices are from $30
