Dobrý deň dá sa tento systém napojiť tak, že do hlavnej jednotky pôjde ethernet kábel a druhá (tretia jednotka) sa napoja výhradne cez WIFI? alebo sa musia navzájom znova prepojiť ethernet káblom, aby to fungovalo?

The Cudy M13 WiFi system is a dual-band Wi-Fi 5 Mesh system that operates on the 2.4GHz and 5GHz bands with a total transfer speed of up to 1167Mb/s. This stable network solution is powered by a dual-core 880MHz processor, supported by 128MB of DDR3 RAM and 16MB of flash memory. The device reliably covers your entire home with a stable wireless signal and eliminates dead zones using four internal antennas, all without complex configuration. The system effectively replaces traditional routers in areas with poorer coverage and ensures your network runs smoothly.
The Wi-Fi 5 standard ensures the smooth running of common network activities. The system offers speeds of 300Mb/s on the 2.4GHz band and 867Mb/s on the 5GHz band. MU-MIMO technology enables simultaneous communication with multiple devices on the 5GHz band, while the Beamforming function directs the signal straight to connected receivers. This gives users a more stable connection for smooth, high-definition video streaming and seamless web browsing.
Cudy Mesh technology links multiple units into a single robust network with a shared name. The Fast Roaming feature ensures end devices automatically switch to the strongest node in milliseconds without interrupting downloads. Depending on the package variant, the system covers an area of 160m² with two units or up to 220m² with three units. The recommended limit is 50 connected clients per unit, with a hardware capacity of up to 128 devices.
The network is protected by modern WPA, WPA2, and the latest WPA3 encryption protocols, complemented by WEP and WPS security. The built-in SPI Firewall and DoS protection actively defend the network against external attacks. Administrators can easily set up secure, separate networks for guests using the Guest Zone feature. Parents can use advanced parental controls with scheduling options and the ability to block inappropriate websites. VPN server and client support includes WireGuard, OpenVPN, IPsec, and Zerotier protocols.
The device has two gigabit RJ45 ports for reliable wired connections. The default setting designates the first port as WAN and the second as LAN, although in Mesh satellite mode, both connectors function as LAN. Power is supplied via the included external 12V⎓1A adapter through a standard DC jack. A wired connection reduces latency when gaming or transferring large amounts of data.
