How Do You Know if Your Modem Is Not Working
Does our modem router no longer work well and the internet connection has problems? How to find out the causes, if information technology is broken and how to prepare it
All of a sudden our Internet line has stopped working, preventing us from continuing our piece of work or blocking the viewing of the picture or Television receiver series we were enjoying in streaming. Many times, understanding where the problem is could evidence to be a hard chore, specially if the modem nosotros use to plant the connection breaks.
Even if modern modems / routers are robust plenty to withstand the most disparate situations, a coma, a violent storm or other external factors (not least continuous downloads and uploads) may suffice to damage the logic board contained in the modem.
In this guide we will show you how to realize that the modem in apply is broken by some signals (some easy to understand, others less easy) and in the case what to practise to solve.

1) Check the LED lights
The modem can immediately provide us with data on the connection and its health by means of the LED indication lights on the front or top of information technology. The lights change according to the model, but yous can notwithstanding find directions by checking these 3 elements:
- Power light: shows that the modem is properly switched on and receives electricity; this low-cal must be fixed and non flash.
- Connection light (ADSL, VDSL or Fiber): indicates that in that location is an actual connection betwixt the modem and the phone exchange (in jargon called carrier); this light must be fixed, otherwise at that place is a problem betwixt the modem and the control console (phone cable or cobweb optic cablevision, telephone socket, cabinet etc.).
- Line low-cal (Cyberspace): this lite (not always present) indicates that we can connect to the Internet correctly; it must also be fixed.
To avert confusion in modern modems it is joined together with the connection modem, becoming a single LED light for Net connectivity. Nonetheless, this concept is wrong, given that it tin can be a carrier merely not surf the Internet, running the risk of not understanding what is wrong with the modem.
If we take to cull a new modem, and so choose one that has a light for the connection and a light for the Internet, and so as to immediately understand where the problem is present.

ii) Check the connectedness cable
After checking the modem lights the trouble is the carrier?
In this example we will have to bank check the connectedness cable that goes from the wall socket to the modem, in the appropriate port (DSL, ADSL or VDSL, based on the technology in use).
Let's effort removing the cablevision and reinserting it, also eliminating any ADSL filters and connecting the cable directly; if yous utilise VDSL connections, the filter is completely useless then nosotros tin remove information technology without problems.
If the modem is not navigating or still having problems, we can endeavor to buy a new RJ11 telephone cable (6 €) or a new ADSL filter (3 €), if we nonetheless employ this connection technology.
We don't know the departure between ADSL, VDSL and optical fiber?
Nosotros advise you lot to investigate these terms in our detailed guide here -> VDSL, FTTC and FTTH fiber: which differences and which is better?
3) Check DNS parameters
Is the carrier present simply the devices are not navigating or the Internet light is off?
In this case the problem does not concern the telephone substitution and the connexion of our modem, but could concern the network infrastructure of our operator (issues on distribution lines or backbones). In this example there is trivial we tin do but report the problem to telephone assist; nonetheless, as a final resort we can alter the DNS servers, one of the infrastructures used to browse the Internet correctly.
To change the DNS on PC we refer you to reading our dedicated guide -> If the DNS does non respond, how to resolve.
If instead nosotros wanted to change the DNS on our smartphones or tablets, we refer you to reading the guide present here -> How to change DNS on Android and iPhone.
iv) Bank check the Ethernet or wireless connection
Does the Internet work properly on some other device on the network?
Then the problem could be i of the modem'due south Ethernet ports or incorrect configuration of Wi-Fi connections.
If our device is connected via Ethernet cable, nosotros can try ane of the other similar ports on the back of the modem: if the connection is nowadays, it means that the LAN port is defective or has some electrical problems (best avoided).
If the other ports are busy and we don't know how to connect the device, we can always increase the number of ports using a working LAN port and connecting an Ethernet switch (€ eighteen).
If the device is connected via wireless, we must enter the modem configuration console, take us to the menu Wireless and change the transmission channel for the 2.4 GHz frequency.
We choose one of the less crowded wireless channels, so every bit to minimize interference with nearby networks and other wireless devices. If our modem has a v GHz wireless connection, it is time to configure it and use it on devices that have a dual Wi-Fi module, so that you tin can surf the Cyberspace using a faster and less susceptible to interference network.
To deepen the word on the differences between the two types of network, we refer you to reading our dedicated guide -> Differences between two.4 GHz and five GHz Wi-Fi networks; which is better?
5) Conclusions
By carefully following all the steps described to a higher place, nosotros volition need to be able to understand if the modem router is faulty or has only a temporary problem, easily solved.
If none of the methods described above work, change modems or telephone call for assist it may exist useful to completely reset the device: we identify the small hole with the word RESET (usually nowadays in the back), insert a needle inside for about ten seconds, and then release it and observe the behavior of the modem.
With a little luck we could solve most of the software problems without even changing the modem.
If, on the other paw, our modem does not accept 5 GHz connectivity, it will not work well despite the reset or information technology is damaged to the point of not allowing us to surf the Internet, nosotros advise you to equip yourself with a last generation modem router, like those recommended in our guide -> Best WiFi Routers to connect wireless devices at domicile.
