Wi-Fi Ethernet and LAN Design

If the device count is only slightly above the router’s available ports, adding a switch is often the simplest answer. The main thing is to think about growth, power, physical layout and whether different types of devices should be kept logically separate. A router is there to manage connectivity and policy; it does not need to be forced into every local-network job. Comset can help decide whether a four-port router is enough on its own or whether the cle…

Yes, provided the router has the right local interfaces and the LAN has been designed sensibly. In a smaller installation a router may directly connect a few wired devices and a Wi-Fi access point. In a busier installation it may be better to let the router handle the WAN side while a switch and dedicated access point deal with the local network. Comset normally treats that as a local-network design question rather than a SIM question. The number of Ether…

Use a separate access point when the Wi-Fi coverage area is large, there are many users, multiple floors, metal obstructions, specialised antennas or a need for modern roaming and central management. The router’s built-in Wi-Fi is convenient for commissioning, a small room or a few local devices, but its ideal cellular location may be a poor Wi-Fi location. Separating the functions lets the industrial router sit near the cellular antenna or equipment cabi…

Use VLANs to separate management, industrial equipment, cameras, staff devices and guest access. Apply firewall rules so each group can reach only the services it needs. The router’s administration interface should not be exposed to ordinary users, and remote access should terminate in a controlled management network rather than the whole LAN. Change default credentials, disable unused services, restrict administration by source address and keep configura…

Count every local device that needs a wired connection, then allow for a management laptop, future equipment and any uplink to a switch. If the router will serve only one controller, two ports may be enough. A camera or small office deployment may need a separate managed switch rather than a router with many built-in ports. Port speed should match the traffic. Gigabit Ethernet is sensible for 5G, high-rate cameras, local file movement or a fast WAN; 100 M…
