How to find out who else is connected to your Wi-Fi network, check ping and overclock the Internet

Everybody knows, what is wifi… They all have Wi-Fi. You better show me who doesn’t have it. After all, wireless internet is so convenient. There is no need to lay a cable, no need to worry about its safety, and you can connect from several devices at once, even being at a considerable distance from the access point itself. It is enough to know the password. Another thing is that situations are not uncommon when, having learned a defensive combination, someone else is connecting to your Wi-Fito whom you did not give your consent. This means that it is necessary to somehow bring uninvited users of the wireless Internet to clean water. But how?

Suspect someone is connecting to your Wi-Fi? This can be checked

Since most users have either rented or very simple routers, there is usually no way to connect to them using the application. And, even if there is, then people simply do not want to do this. They need the simplest solution that would do everything for them: connect to Wi-Fi, count all connected devices and show them. Then the matter is small – just change the password and reconnect yourself again, and leave uninvited guests without the Internet.

View devices connected to the router

An excellent host scanning solution – ScanNet – Network Scanner application… Looking ahead, I will say that it allows not only to reveal all devices connected to the local networkbut also to identify problems in the quality of the connection. However, first things first.

  • Download ScanNet to your device from Apr Store;
  • Run the application and on the main page, click Scan;

Please note: the names of only disabled devices are not determined. If you connect them, at least the brand will be determined by the application, and you will understand whether someone else is connected to your Wi-Fi or not.

  • Wait for the scan to complete and recount all detected devices;
  • Click on each one for details.

In my case, there were as many as 6 devices, not counting the router itself: an iPhone, a MacBook, two iPads, an Android smartphone and a TV. Not the entire application has been identified correctly. He simply marked some gadgets with an IP address without recognizing them. But this was due to the fact that they were simply disconnected at that moment. The main thing is that I know which of these devices are mine.

Scan local network

You can manually set the scanning method you need in the settings

Network scanning via ScanNet is performed in four modes:

  • Read arp
  • ICM Ping
  • UDP Ping
  • DNS Request

Read arp mode is enabled by default. Its difference is that, firstly, it scans including disabled devices (this is how the turned off TV turned out to be on my list), and, secondly, it only works on the local network. Therefore, if you need to exclude turned off devices or go outside the local network, you will need to select a different mode.

The application gives out devices not just in a list, but also allows you to view information about each of them in all details. This will include the hostname, ping rates, and open ports. In general, everything that may be required even for professionals, and not only for ordinary users, who most likely have not heard about ping, not to mention everything else.

For advanced users, ScanNet offers a wide range of search configuration tools

With ScanNet, you can scan the networks and ports you need and find the hosts connected to the router

For advanced users ScanNet offers a fairly wide range of settings. So, if the standard search settings do not suit you, you can configure it as you like. If necessary, you can scan not only home network, but also the generally selected range by setting IP address limits.

let’s try scan your IP range:

  • Open the app ScanNet on your iPhone;

Scanning external networks is rather a tool for prosumers and specialists

  • Click on the menu button in the upper right corner;
  • Select “Tools” – “Scan external network”;

ScanNet will provide comprehensive information about the networks you are looking for, port openings, etc.

  • We set the scanning method, set the ranges and click Scan.

Setting ranges, of course, is a tool for advanced users or, I would even say, for specialists. It allows you to find the server you need, diagnose, and much more.

The only drawback is the lack of opportunity get MAC address scanned device. However, this is not a limitation of the ScanNet app, but of iOS itself. For two years now, Apple has been blocking mechanisms that receive this information, preventing developers from embedding them in their software. Therefore, the iOS version of ScanNet does not have this option, but in Android version – there is.

How to check ping

For a fragile ear, everything that was described above may sound difficult, I agree. But knowledgeable people will perfectly understand what’s what and will be happy. However, if you are not one of them, there is nothing to be afraid of. The application has a completely simple and intuitive interface. And for users who do not want to bother with technical details, there is a basic toolkit.

In my case, the ping is very good, but if your indicators are off scale, you can try to fix it

Thanks to him, you can not only find devices connected to home network, but also to diagnose it. Let’s say your internet connection isn’t working well on your phone. Most likely, the point is in ping, and using ScanNet you can check it and determine if there is a delay and how critical it is.

Normal ping rates can vary widely. But the smaller it is, the better. ScanNet measures it quite accurately and allows you to understand if there are any problems on the line. After all, it happens that the connection itself has a fairly high speed, but until the signal reaches the smartphone connected to the network, it sags greatly.

How to lower ping on your phone

Ping sag may be due to the fact that too many devices are being used on the same broadcast. This is a very common practice for apartment buildings. But there is an opportunity to tweak something. To get started, go to the router settings and select “Additional settings”. Then follow the instructions:

  • In the “Frequency channel” section, set the value to 2.4 GHz N;

Setting these parameters can really help you. True, depending on the manufacturer of the router, the settings may differ

  • In the section “Frequency channel width” setting the value to 20 MHz;
  • Then select “Short preamble type” if set to long;

If not all settings are available to you, set only those that are

  • Disable aggregation and set the output power to 50%.

Download ScanNet

It is not a fact that this method will work in your case. In the end, the reasons for this can be very different: mismatching router settings, lack of technical ability to access them, others problems on the linepreventing the signal from passing at the desired speed. In general, there are always plenty of reasons to say no. But at least try it. Because ScanNet cannot be wrong.
