Sometimes we feel like our home internet connection isn't up to par, especially when we're working remotely or want to play online without lag. It's frustrating when other devices are lightning fast while our console or PC freezes, and even after trying to restart the router a thousand times, the problem persists. Often The solution is not to change operators.but rather to optimize the way we distribute the internet in our home.
If you've noticed that your Wi-Fi doesn't reach all the rooms or that your router's ports are insufficient, you probably need a switch. This little device is like a power strip, but for the internet; it allows us to add more Ethernet ports so that more devices can be connected by cable, which translates into brutal stability and fewer fights over bandwidth on the wireless network.
What exactly is a switch and what is it used for?
To avoid confusion, a network switch is a device that expands the number of available Ethernet ports. It's essential to understand that It does not replace the router Nor does it magically generate internet. The router remains the brain that manages the incoming signal from outside, while the switch is responsible for distributing that traffic among the devices inside the house.
Imagine you have a router with four ports and you've already connected your TV, game console, and computer. If you want to add more devices, a switch is the ideal solution. By connecting devices via cable, we achieve decongest the wireless networkThis prevents so many devices from competing for the same WiFi signal, improving the quality of video calls or 4K streaming.
When to buy one and when it doesn't make sense
Not everyone needs a switch. If your problem is that your 300 Mbps fiber optic connection doesn't reach the 1 Gbps you want, or if there's no WiFi coverage in the back room, The switch won't work miraclesIn those cases, it would be better to look at a mesh system or change the router's location. A switch shines when you have the option of running cables throughout the house and want to... the connection is more stable.
It's especially useful in new homes that already have RJ-45 jacks in every room. Often, the router only has four ports and the house has five or six; that's where the switch comes in. connect all rooms without having to juggle cables across the hallway.
Buyer's Guide: Key Technical Aspects
When choosing one, don't just go by price. There are details that can make the difference between a smooth network and one that has problems. The first is the number of portsCalculate how many devices you currently have and allow a 20% or 30% margin for future needs. A 5-port model is sufficient for small apartments, but for larger houses, it's advisable to opt for an 8-port or even a 16-port model.
Another critical point is the IGMP snoopingIf you have a VoIP (Voiceover) service (as with Movistar TV), your switch needs to have this function. If it doesn't, TV traffic can saturate the network and cause problems. The internet keeps cutting out on other devices.
You also need to decide if you need PoE (Power over EthernetThis technology allows you to send electricity and data over the same cable. It's fantastic if you're going to install IP security cameras or WiFi access points on the ceiling, as it saves you from having to put a socket next to each device.
Manageable versus unmanageable
Most people get carried away by the switches unmanageableThese are the "plug and play" models. For 95% of households, they're more than sufficient. However, if you're an advanced user or work in IT, you might want one. manageable or SmartThese allow you to create VLANs to separate the guest network from the main network or the home automation network, improving security.
Regarding materials, I highly recommend you look for metal housingsIt's not just for aesthetics; metal dissipates heat much better than plastic, which prolongs the life of the device, especially if the switch is inside a telecommunications cabinet with poor ventilation.
Troubleshooting common connection problems
If you already have the switch but are still having problems, there may be a configuration error. A typical mistake is creating a network loopThis occurs when you connect two cables between the same switch and the router without special configuration, causing the network to crash. The correct practice is to use a single uplink port to the router.
If a PC doesn't have internet access, it's advisable to check the network topology. The switch should always be connected. behind the routerIf you connect it directly to the modem, it's very likely that only one device will be able to browse the internet, while the others will be unable to. If the problem is with the IP address, perform the following: ping tests Testing between two computers connected to the same switch helps to rule out whether the problem is in the hardware or the router configuration.
For those experiencing specific issues with consoles like the Nintendo Switch, the problem is sometimes the Wi-Fi card or interference. While using a mobile hotspot is a temporary solution, wire the console Using an Ethernet dock and a switch is the only way to guarantee that there will be no interruptions during online games.
To keep the equipment in good working order, it is recommended to clean the dust with compressed air and check that the RJ-45 cables They shouldn't be bent or peeling. A quick power reset now and then can also help clear the device's memory and maintain peak speed.
Choosing the right equipment depends entirely on how many devices you want to connect and whether you have IPTV services or devices that require wired power. Prioritizing quality materials and including features like IGMP Snooping ensures a robust, scalable home network that won't cause headaches when gaming or working.
