Can I leave the wifi password by default?

As I promised you, I wanted to talk to you about the wifi key. Sometimes I hear family or friends asking me ‘Can I default my wifi password? ‘ And they argue that they have not changed the wifi password because the one provided by their supplier is complicated enough and there is no God who can guess. They’re partly right, We’ve already seen how it should be a password to be considered safe.But with the wifi passwords, it gets a little complicated.

More. Let me first tell you a few things about the wifi networks:

The Wifi networks have been between us for a few years now. At first they seemed a very good idea, an easy, fast and cheap way to expand the perimeter of my network and also without having to be ‘tied’ to a network cable, so it allowed some mobility within the reach of it. That sounds good, doesn’t it? But he also had his contras… until that moment, with conventional cable networks, for a malote it would sneak into your network, I had to go in with some excuse to your house or company and connect your laptop to your network. Once inside it could already spread a virus, access folders or printers

shared, browsing the Internet… almost anything… but of course, It should be inside. Which wasn’t easy. However, with the arrival of the wifi network the thing changed… it is clear that the coverage is not great in a conventional network, but it is powerful enough for the guy who wants to get into our network to try it from the home door, or by approaching one of the windows… the coverage will surely come to him.

Since cable networks did not have too much access control (because you had to be inside physically), The first wifi networks didn’t have it either.… until someone found out that he had all his neighbors connected and thought it was not fair that only he would pay for the connection, so he decided to implement a security and encryption layer, not only so that no one could connect but also so that they could not capture the traffic their neighbors… and the first attempts were of laughter, it had to be several years before it arrived. WPA2 to encode and protect access to our wireless network b

rich.

I’m not going in to explain what WPA2 is and why it’s safer than WPA and WEP, but It’s the only system you should have on your network if you want it to be safe.. If your router from a few years ago does not support WPA2 and only has WEP and WPA, you should change it for a more modern one. Even WPA2 is not 100% safe, but if we combine WPA2 with a good password… we’ll have a pretty robust system., enough that if someone wants to attack us, consider it complicated and go find another neighbor more ‘collaborator’.

What is a good password for WPA2?

A good password means we have to look a password similar to the one we would put in one of our services, created just as we commented a few days ago on the link I’ve already put you up.

Okay, well… but why all this? My router already had a hard password when Mr. de Ono brought it to me.

Most manufacturers and suppliers, When you get the router, you already have a sticker with a password. that meets everything we commented on the other day, but in this case it’s not worth it because That key is generated by some program. of the supplier. I explain: I do not know if you have noticed that there are many networks with own names (at the moment, mine is called TALETS) but there are others with more generic names like MOVISTAR _ 67CD or ORANGE _ 89323H. With these rare identification names the supplier generates passwords… there’s no guy thinking ‘Let’s see, route

r new that we just made… because I put a password that has a letter, a weird character, a capital… ‘For this, do you imagine? They use a program based on the name of the network, so everyone with a network called MOVISTAR _ 67CD has only a few passwords created automatically. Thank God it is not just one for all who have the same network name, but there are not many more. Less than 10. I mean, all those people with the MOVISTAR _ 67CD network have one of those 10 passwords… if someone’s 10, they can go testing it until it comes in. And you can think ‘but… how will someone get those 10 cons

because there are malotes with a lot of free time and sufficient technical knowledge to know this and to be able to generate a program to search for these keys… so that if you look in the Apple App Store or Google Play Store, you will see a multitude of programs to connect to Wifi networks, some of which identify the generic name and search their database for the passwords generated by the manufacturer for that generic name

And they start testing all this automatically and in a matter of seconds. Cool, right?

So what should we do with our wifi to make it safe?

Well, summarizing a lot and without going too deep, the steps you should follow are:

– Change the network name to a less generic one. Don’t put a name like ‘Attack me if you can’ either, something discreet to be possible.
– Make sure the wifi is using the WPA2 system.
– Change the key to that network and generate a good password as we saw a few days ago.
– Change the router management key, the same one you used to change the network key.
– Leave the key to people of trust… just like the neighbor we get along so well and let our wifi be used by, he gives it to other neighbors we don’t get along with.
– Change the key from time to time… you don’t have to be all the energies, p

Or you don’t keep the same key for years and years.

And even with all this, if you suddenly notice that your network is starting to go slower than normal or you are suspected that someone could have your password (yes, that neighbor-brother-in-law who smiles DEMASIADO in the elevator and who looks like Sticky), the best thing is to change the password. Don’t think ‘on my estate there are only older lords, I don’t see any of them trying to hack my wifi’ since those older lords always have kids, friends or granddaughter’s boyfriend who pass through their house from time to time and who could look at your wifi if they get enough coverage.
