Power over Ethernet (PoE for short) connectivity simplifies cabling needed to connect a device by allowing power and data delivery over a single network cable such as CAT5e or CAT6. It makes it easy to connect devices such as IP security cameras, wireless access points or office phones; a separate power supply or electrical outlet… Continue reading What’s the Difference Between Active and Passive PoE?
A hub, switch and router are all devices that you might find on a network. Often you will find many routers contain a built in switch (multiple LAN ports) A router is used to send data packets across different networks IE: your home network to the internet. A hub and a switch are used to… Continue reading Switch / hub / router – What are the differences?
Installing a wired network socket is the same idea as installing a telephone extension point in a different room – for example a kitchen, or bedroom. It provides the flexibility to plug in and unplug devices without the need to leave a trailing cable. This is especially useful in areas which have multiple uses: IE:… Continue reading Why would I use wired sockets
A patch panel is a panel of network ports in a central location. They are usually located in server racks, or next to a modem / router. They allow for easy connection of network sockets throughout a property as simply as you’d plug in a vacuum cleaner in different rooms of your house. Not every… Continue reading What is a patch panel? Do I need one?
When you’re suffering from poor WiFi signal there are usually a few options you can take to resolve the situation yourself. However, sometimes there are items of furniture you can’t move, or you cant move the router. What can you do then? The first option you have is that you can use a device known… Continue reading What is a wireless access point and a wireless repeater
WiFi also known as Wireless Fidelity is essentially the same thing as saying WLAN which stands for “Wireless Local Area Network”. WiFi uses radio frequencies in the Gigahertz range to send signals between devices. WiFi uses the frequency at the 2.4Ghz and 5Ghz range. As a note, your microwave uses a very similar frequency at… Continue reading What can limit WiFi signals
A routing table is an information database that is contained within a network host. It lists the routes that different network destinations should take. The table will include information about the network topology directly connected to the host, and therefore allows numerous networks to interconnect. These networks can either be private local networks (LAN) or… Continue reading What is a routing table and do I need one?
A network cable is terminated with eight wires – usually to a jack plug, or socket – using a specification – T568. T568 has two different specifications: T568A and T568B. T568A uses the following pin layout: Green / White Green Orange / White Blue Blue White Orange Brown / White Brown T568B uses the following… Continue reading Patch cable and Crossover Cable – What are the differences?
A typical ethernet cable has eight wires. You also have shielded cables which contain a grounding pin. For an ethernet connection to work, you only need to use four of these wires – two transmit wires, and two receiver wires. This leaves two pairs of wires redundant in most cables that can serve a different… Continue reading What are ethernet splitters
At my own home, I need access in many locations. Commonly in the back garden, and the office, to the rear of my property – but my main router is located at the front of my property. One of the first major improvements I made was to use a few cheap WiFi repeaters within my… Continue reading My own home network
