Why does the internet sometimes lose connection?

How many times, a small yellow warning icon and the words "No internet access" make us miserable: unable to send documents on time, unfinished a film to the climax or watch the player at stand still just because . disconnected. So, why does the Internet sometimes "become" like that?

Except for the problems arising from the Internet service provider we are using (such as sharks, for example), there is a remedy that even amateurs can do, It is to check the signal light on the router, then restart it by pressing the power button on the back of the router or make sure to unplug and re-plug the power plug. But why just by such a simple method will help the Internet return to the "golden age" as if nothing had happened? To partially reduce the problems in your head, let's go through some scientific reasons to find out why sometimes the internet is interrupted so suddenly.

Complex structure inside

You might think that the router is just a compact, simple box and just plugging in the cable can connect to the internet. But to be able to handle that "connection" task, inside it is a rather complex structure of electronic components. In general, a router will include CPU, memory, main PCB board, input, output components, and have a separate operating system - the structure is quite similar to a regular computer. . Dozens of these components will be responsible for ensuring good bandwidth management, but they can sometimes be overloaded.

If you can slow down your laptop or PC by opening multiple browser tabs, playing multiple 4K videos at the same time or playing high-profile games, the same is true for routers: pushing tons Data across multiple devices can clog the router - sometimes causing overload and forcing it to stop.

Dynamic IP

Internet service providers only assign these IP addresses to devices for a certain amount of time.

Dynamic IP is an almost common cause when it comes to network access errors. Simply stated, the IP address is an internet protocol that enables the internet connection to reach your right device. Internet service providers only assign these IP addresses to devices for a certain amount of time. When this time is up, they will assign a new address, which is how the "dynamic" IP works. Sometimes, the amount of data that is too high will cause the router to be unable to connect to the new IP address and will continue to search for an old address that has expired. This is quite similar to the fact that one of your parcels is delivered at the old apartment address, even though you have updated your new address.

The space is cramped, dusty

The router is an electronic device, and of course electronic devices when operating will generate a lot of heat and performance degradation occurs when the device becomes too hot. Therefore, it is not difficult to understand when manufacturers create large heat sinks on routers, but the manufacturer's intentions may become useless or even counterproductive if you throw them away. they are in a cramped corner with ventilation vents blocked by dozens of cables and other objects around.

In addition, if you do not clean the router regularly, long-term dirt will also prevent heat from escaping. Make sure the router has enough space for it to "breathe", not to choose places that are too cramped or too many things around and ensure its regular hygiene.

Noise interference

This problem usually occurs on routers that use wireless connectivity. With its compact and convenient nature, most home internet connections today use Wi-Fi. But sometimes the wave also occurs overload, especially if Wi-Fi operates on the popular 2.4GHz band. Noise emitted from ordinary household appliances such as microwave ovens or even signals from nearby routers, if on the same frequency can overlap (noise phenomenon), causing difficulty towels for receiving devices (phone, TV or computer).

In case you accidentally fall into this situation, you can access the router's settings and change channels, or you can switch from the 2.4GHz band to 5GHz - if your router supports it.

Some software problems

Sometimes, the problem of poor internet connection lies in the faulty software, application or application.

Specifically, using a device with software or an outdated driver can sometimes lead to problems while connecting to the network. Therefore it is necessary to ensure that the latest version of the operating system is updated. Or sometimes, uninstalling and reinstalling Wi-Fi drivers can fix internet connection problems.

Extensions, plugins or browsers sometimes cause Internet access problems. Switch to another browser or try incognito mode to check if the internet is working again.

Finally, if you are using a VPN to access blocked web sites, it may also be the cause of obstacles in connecting to the internet. Please check the network access on other devices, if the connection is normal, proving that VPN is likely to be the culprit has interrupted your happy surfing time.
