Constantly losing Internet connection over WIFI 1 wifi

This issue has plagued us for a few weeks now with our WiFi connection apparently dropping. The WiFi icon in the system tray would show no problems, strong signal, no errors, yet for some inexplicable reason we would keep losing Internet access and web pages would not load. This would last anywhere from a  few seconds to a few minutes, with Google chrome giving errors like:-

“err_name_not_resolved” or “dns_probe_finished_nxdomain”

This issue was not limited to just 1 PC either, it was affecting multiple devices and was causing some major problems with games, remote desktop sessions, saving pages, submitting forms etc. I tried literally everything I could think of, and every solution I found online, nothing worked. So now I needed to start thinking outside the box. I thought I would share my solution in case it helps others.

The first thing I decided to do was to check whether I was even able to access the router web admin interface when the issue occurred, and it turns out I couldn’t. So I decided to run a continuous ping in the background to see if there was packet loss, there was, in fact, it was now happening as often as every few minutes when 4 or more packets would be dropped and the ping would timeout.

The most obvious conclusion would be that it was the router, however, I had already swapped out the router a while back, so it seemed unlikely that I had 2 routers with the same issue.

Then there is the common problem with interference. However I had already changed the channels to that of neighbouring routers, I had also already tried turning off all possible interference devices such as TV’s in between me and the router or other wireless devices.

Perhaps there was some device on the network that was screwing up the routing tables or causing packet loss? So I reset the WiFi password so that only my PC could connect, and unplugged all wired devices and crossed my fingers. Sadly no dice.

Then I recalled an issue I had a few years ago in my old office where I lost my internet connection, and it turned out to be caused by the power adaptor from my VOIP phone, which was plugged in right next to my router and had become faulty and was leaking electrical interference. Needless to say, it took me a while to figure that one out, and I had blamed my ISP at the time and moved to Zen Internet, and had the same problem. It was thanks to the troubleshooting skills of the ZEN support techs that we found the cause, quite quickly I might add.

So I unplugged all devices near the router, but again no change. The only device still connected was my  Netgear 24 port switch, which I use to extend the number of ethernet ports on the router, surely this could not be the cause? So I unplugged it. Lo and behold, the packet loss stopped. I kept the ping running for several more hours, and have not experienced the random connection drop since.
I guess due to the age of the switch, it had developed the same fault with its internal power supply and was leaking electrical interference.

The dangers of using public WiFi

The dangers of using public WiFi

public wifi

How often do you use public WiFi? Are you aware of the dangers of using public WifI? Do you know how to protect yourself from harm? These are some of the questions that I will answer in this post, so if you or your kids are not currently securing your mobile devices, keep reading.

The Dangers Of Using Public WiFi

Everyone has several points during their day when they find themselves somewhere in public, and they just happen to catch a break. In those times, most people will simply take out their phone and check their favourite social network, email, and similar things.

However, to do so, they need an internet connection, and if they do not have a mobile signal then they will next try to scan the area for public WiFi. Some people even have their devices set to connect to any public WiFu automatically. If you do that, you might think that you are lucky having free internet access. However, you might just be about to enter a hacker’s trap.

Any free public WiFi that you find could actually be a trap set by hackers, but even if it is legit, with such poor protection there’s pretty much no difference. We understand that sometimes you don’t have the time or patience to think about this sort of thing. You might be in a hurry, or maybe you are waiting for an important email, or message.

Even if you use it for a little bit, your phone, tablet, or laptop can still get compromised.

So in this article, I am going to mention some of the most common and dangerous threats that you may come across when using public WiFi. And also some of the methods that you can use to protect yourself from them.

Snooping

Snooping is possible when you use any WiFi network that doesn’t have encryption, and most public WiFi networks don’t, which makes them different from your home network. When you use your private WiFi network at home, it has password protection, as well as encryption (or at least it should).

Public WiFi networks are different, and many don’t even have password protection at all, so as to easily make them available to anyone. Such as tourists and guests of hotels, restaurants, and alike. However, this also makes them vulnerable, as well as convenient.

When you use a network with encryption, your online actions are hidden from others. If you use one without protection, then everything you do is out in the open for everyone else to see. And if you use such networks to connect to your bank or social network, you will make your privacy available to others.
It is basically like sitting in an office with glass walls, everything you do is visible and nothing is private.

If you use public WiFi to connect to your bank, social network or anything else, you will make your privacy available to others

Compromised Devices

When you are using your laptop or some other device in public, and you connect to an open WiFi, make sure to mark it as a public network. If you do so, the device that you are using will lock down the connection. If you fail to do so, your device will treat it as a safe connection, which might lead to exposure.

In case that someone hacks your device, they might get access to all of your private content and info. That includes pictures, potential credentials, business documents, and everything else that you have.

Malicious WiFi Hotspots

The most dangerous thing that can happen to you is to connect to a fake public network.

They will often have a name like “Free WiFi“, or “Public Network“, or something like that. These are networks that hackers themselves set up, and then leave open, and without protection.

They do so in hope that someone would connect without realizing the danger, and most people will do just that. Not everyone knows about this method, and in fact, the majority doesn’t have a clue that this can even happen to them.

Several public WiFi Hotspots are set in place by hackers and left open to steal your online credentials, your business documents, contacts list, messages, emails, and everything else

But, when they do connect to one such network, hackers will see everything that they do.

This is how they steal your online credentials, your business documents, contacts list, messages, emails, and everything else.

They can later use this info to break into your bank account, steal your identity, hijack your social networks, and generally ruin your life for their own gain, or simply for their amusement.

Malware

Getting malware on your device via WiFi hotspot that hacker controls is much simpler for them, and much more dangerous for you. Hackers can use malware for many things. Some of them might only steal your files, photos, and similar data.

There is always a worse option, which is when malware actually downloads even more malware. Eventually, the hacker might get complete control over your entire device. If that happens, there is no limit to what they can do, from locking down your phone, to making it a part of a botnet.

WiFi Sniffing

This method is pretty simple when it comes to its concept. Basically, hackers will monitor network traffic and record big swathes of data that passes through. They can inspect this data later, and try to find some useful information.

This method can lead to discovering someone’s credentials, and other personal information. The consequences are many, and they might steal your money, your identity, or blackmail you if they find some secret.

And the worst part is the fact that sniffing through packets of data is not even illegal most of the time. It depends on the country’s laws, but not many choose to bother about things like this, that only affect several people at once.

Doing these things is actually very easy. Most people imagine that you need a lot of technical knowledge, or maybe some expensive equipment to do so. The truth is that almost anyone can do these things with an app or two, or some program of a higher quality.

The real technical knowledge is pretty much not even needed, and most instructions on how to do these things can be found pretty easily online.

You should have in mind that all of these dangers are a real threat, whether you are in your hometown, or in a foreign country.

How To Protect Yourself From WiFi Dangers

Now that you know what threats are out there, you should also learn how to recognize the danger.

Also, once you do recognize it, how to protect yourself. Some of these methods are something that you will just have to remember, and others will do most of the job by themselves.

Your job is to try to remember as much as you can, and when you can, you should avoid public WiFi. It might not be as convenient, but it is always recommended to wait until you get home. Now, let’s see what the methods of protection are.

Double-Check The Network Before Using It

False assumptions are what leads to most of this kind of problems. In short, you shouldn’t assume that a WiFi network is legitimate just because it says so. You shouldn’t really use any unknown WiFi since you don’t know who it belongs to.

It might belong to a restaurant, coffee shop, or a nearby hotel, or it might belong to someone fishing for easy targets.

Stick With HTTPS

Google Chrome lets you know when the site you’re visiting uses an unencrypted HTTP connection rather than an encrypted HTTPS encryption by labeling the former “Not Secure.” Heed that warning, especially on public Wi-Fi.

When you browse over HTTPS, people on the same Wi-Fi network as you can’t snoop on the data that travels between you and the server of the website you’re connecting to. But Over HTTP? It’s relatively easy for them to watch what you’re doing.

Thankfully all major sites are using HTTPS now, meaning that data is encrypted, but a lot of smaller sites are still using HTTPS and apps on your mobile device also may not be using a secure connection to connect to servers.

Update Your Software And Antivirus

Your OS will get updates on a regular basis, which goes the same for all legitimate apps on your phone or tablet. Installing these updates might be boring and annoying, but it is one of the best ways for you to stay safe.

New vulnerabilities are always being found and patched. If you have a system that did not patch old vulnerabilities, hackers might still bypass your protections. Most of these updates will install themselves automatically, only if you allow that in your settings.

And the same goes for your antivirus, that won’t help much if you connect to a network that hacker controls. However, it will help a lot if they try to send you a malware. That is why you need to keep it fresh and operational.

Forget A Hotspot When You Leave

If you have no choice and it is an emergency, you will simply have to connect to a hotspot and do what you need to do. However, we recommend doing what you must as quickly as possible. And after you finish, forget the hotspot immediately.

You don’t want to risk your phone remembering it and reconnecting automatically every time when you get close to that hotspot. That way, you might allow someone access without even knowing that you are in danger.

Having your phones remember WiFi that you use is practical and convenient, but also very dangerous. This is a danger that you must not overlook, otherwise, trouble is sure to follow.

Use A VPN

Finally, the best thing that you can do to protect yourself is to use a VPN. Using them is cheap, it is easy, and they will follow you always, and protect you no matter where you are. Even if you connect to a public WiFi.

VPN stands for Virtual Private Networks, and their main purpose is to help you stay safe online. They have multiple methods of doing so, which all add up to one big protective app that you can download on any device.

Depending on a VPN, there are different features that you can use to enhance your protection.

However, three main features are what they all have in common;

  1. First of them are security protocols. In order to keep your data safe, VPN can create a protective tunnel around your data flow. Your data goes through this tunnel, and while it is inside, nobody can use it, see it, or record it. With this method, your online actions are safe and under strong protection.
  2. The tunnels are not perfect, and there might be a leak. Still, there is nothing to worry about, because VPN’s also encrypt your data, just in case something like this happens. They use strong encryption that will keep everything you do protect. Even if someone somehow manages to get through your tunnel’s protection, they won’t know what they are seeing. And these protections are so strong, that some of them have never been breached before.
  3. Finally, they offer large server networks that can change your IP address. Thanks to this, nobody will connect you to your online actions, since they will go to another IP address, while you will remain completely safe and anonymous.

As mentioned, VPN’s offer a lot of extra features. Some of them serve as an enhancement to the existing methods of protection. Such as DNS leak protection, that will make sure that your tunnel has an extra layer.

Others will make sure that your protection will remain even if something disturbs the connection. This is what kill switches do.

All in all, whatever features they offer, the best VPN’s will protect you as best as they can. They will do it by blocking out hackers, stopping malware, and even by blocking ads.

To buy a VPN service is economical. You can subscribe to one of the best VPN starting from as little as £2.45 per month. Considering that your privacy and safety is at stake, it is well worth to give it a thought.

You can also use a VPN router, here is a guide to buying the best VPN router.

One thing to be aware of, many people believe that using a VPN hides your online activity and makes you completely anonymous, this is not true. Your online activity is tracked by more than just your IP address. Your apps on your mobile devices and the cookies in your browsers are sending information about your activity all the time, allowing advertisers to track you around the internet.

Which VPN To Choose?

Because of their sudden popularity which keeps on increasing, there are now hundreds and hundreds of different providers. Choosing one is hard enough, but choosing a good one can be even worse.

Here are some of the most popular VPN providers. I personally use Tunnel Bear right now, and each account allows up to 5 devices to be connected. So depending on the size of your family, then a single account could be used for your entire family’s smartphones.

According to sources, all of these are strong, fast, cheap, and they will give you the best protection that you can find, at the time of writing anyway.

Conclusion

Using public WiFi hotspots can be risky without a VPN, but you sometimes can’t help it. It is understandable, but you should still try to avoid doing it when possible unless you have a VPN to protect you.

However, when you find yourself in a situation that you have to use one, try to remember what you should and shouldn’t do. Do not log into social networks, emails, and especially don’t connect to your bank account. Also, try not to pick something that looks like it is offering itself too strongly.

And of course, subscribe to a VPN, and always have it on your devices. Many VPNs allow multiple connections at once, which means that with one subscription, you can protect 3-5 of your devices at the same time.

So remember these things next time when you choose to connect to a public WiFi hotspot and try to stay safe.
