Yes speed drops considerably on a Wi-Fi network It is not only due to interference that may exist, but also to the connection of unauthorized devices.
Namely, every time the WiFi performance drops it is probably because there are people who cracked the access password. This creates problems in the since anyone can enter the computer remotely and see private.
To avoid these drawbacks, You will need to strengthen your WiFi. If you want to know how you can shield a modemPlease pay attention to the following paragraphs. We will explain all the details.
Why shouldn’t I let my Internet connection be stolen by my WiFi network?
At present, most of them work in two frequencies. One of 2.4GHz and the other of 5GHz, being the first one the one with the longest reach and the lowest connection speed. This is due to the 14 channels with which it works to transmit the signal. The 5 GHz frequency has a much shorter range, but it has more than 20 transmission channels and therefore a better speed.
With this we can determine that if someone is stealing the WiFi signal it is likely to be on the 2.4 GHz frequency, since in it it is easier to detect that its performance decreases. As there are only 13 + 1 channels for its operation, it is easier for these to saturate and do not have the intensity for efficient signal transmission.
Therefore, the optimum would be that there are few mobile phones and computers connected at these frequencies. If they steal the WiFi signal they will occupy one of the channels. Therefore, the saturation will be greater, causing a significant decrease in the performance of the network.
Learn step by step how to know who connects to your WiFi network from your mobile without your permission
Next, we will show you the steps that you must follow on your mobile to find out who connects to your WiFi network:
on android
Download the Net Scan app and follow this guide:
- Open the app, go to the option netscan.
- Choose the network which you want to analyze.
- enter the same typing the password.
- A list will appear with connected devices, address MAC and IP.
- Control your devices with the ones you see in the list. If you find a suspicious one you should change the PIN to access the Wi-Fi network.
on iOS
The steps that you must perform on your iPhone or iPad are the following:
- Download the app “Fing” of the app store.
- Once you have it installed grant the necessary permissions.
- You will then see the name of the network to which you are connected at the top left of the screen. If you want to change to another network to which you also have range, you must click on the arrow to display the menu.
- when you have chosen the network select the tab “Devices”. After a few seconds, a list will appear with all the connected equipment, brand and operating system.
- If you want to expel someone in particular, you must change the password to access the router. In case you need to know if it connects again, you will have to select the device, go to the bottom of the screen and activate the option “Notifications”.
Tips to configure your wireless network in a much more secure and private way
If you want to have a completely secure WiFi network, pay attention to the following tips:
Use MAC filters
One of the fastest and most secure ways to shield the WiFi network is configure the router so that only devices that have a set MAC address can access it.
For this it is necessary to know it, if you do not know how to do it we will explain it to you:
- On Windows: press the key Windows+Rwrite cmd and then run the command ipconfig /all.
- On a Mac: go to the menu and choose About my Macthen tap on More information and lastly in system report.
- On Android mobile: Choose Settingchoose Wifi and then advanced settings.
- On an iPhone: click on Settingtap on General and finally in the option About.
once you meet , You will have to Enter your router’s configuration panel with your browser.
To do this, you will have to follow this process:
- Write in the address bar “”.
- enter username and password to access.
- head over to tab “Wireless”.
- press in option “MAC Filters”.
- Next, you will get into one by one the MAC of authorized devices. Every time you finish you will have to click on “Add”.
Frequently change the SSID and password
Everytime that change the name of the wifi network it will take longer for the intruder to know which signal belongs to you. Although this will help you when there are many networks, it is also good to apply it in areas with poor wireless Internet coverage. You will have to choose names that are not related to you.
In addition, you will have to change the access password. We recommend that you use symbols, capital letters, and numbers when choosing a new PIN. You must bear in mind that it has to be easy for you to remember, but knowing that you cannot choose birthday dates, addresses, names of your relatives or any other information that can be obtained by logical deduction.
Disable the WPS security protocol
Typically, routers They come from the factory with the protocol activated. In this way you can enter a 8-digit PIN instead of the password to access the WiFi network. This creates big problems when it comes to protecting security since it is very easy for hackers to access the network by this means.
Change security encryption to WPA2
There are applications that can be installed on any mobile and obtain access to WiFi by means of a PIN, then you will need to connect to the router to find out the password. This can be done as long as the security protocol is not , since it is much more efficient than the rest.
To carry out this type of configuration you will do this guide:
- Enter the router configuration panel by typing in a browser “192.168.1.1” and then the access password.
- Click on the option “Wireless Settings”.
- Choose “Security” and choose the tool “Authentication Type”.
- Click on “Save”.
You must do these steps in each of the router frequencies. That is, in the 2.4GHz and in that of 5GHz.
Hide WiFi signal
This will make no device can pick up the WiFi signal. To enter the network you must write the SSID and then the password. That is, you will not do it automatically how you do it every time the mobile detects the signal.
To strengthen the WiFi, you will have to follow this process:
- enter to the settings panel and then go to “Network”.
- Then tap on “WLAN”.
- Choose the tool “SSID Settings”.
- active the box “Enable SSID”. On some devices you will find it as “Hide WiFi network”.
