In today's world, we need the mobile in front of you and your eyes from waking up in the morning and to go to bed at night. And not just mobile, It should have internet or in other words a data pack. 1.5-2.5 GB per day is not enough To anyone, so we bring a Wi-Fi Router like family pack ice cream.
If we compare it with family pack ice cream and say that we bring it home in the heat of the day and bring it back and look at the bag, then someone has stolen it. Don't feel so bad?
Also, think if someone takes your internet Wi-Fi network? Yes, Of course, today we are going to talk about Wi-Fi network security. Before that, we will see a little bit about the Wi-Fi network connection. There is a common misconception that Wi-Fi is an acronym for wireless fidelity, but it is not. Wi-Fi is a trademark meaning IEEE 802.11x.
Some say, students, say, thieves, say enemies, or any other person these days. They are all looking for a free internet data source for their work or entertainment. There are also gangs of thugs (hackers) waiting in line for insecure Wi-Fi in the hope of finding and logging in to an unsafe home network, They are waiting for Wi-Fi with a hook, and that is how the throat gets caught like a fish on your home Wi-Fi Router. So we need to secure our Wi-Fi Router and also your home.
So, first of all, you need to know how to change the settings of your wireless router! For that, you have to type 192.168.1.128 or other IP according to your router, in your web browser. Then on the page that opens, type the username and password of your wireless router. Your wireless router is different depending on the manufacturer. For that, you can see the user manual of your router, which you never keep correctly. And don't worry because you know this, you can search for it on Google.
You may know some of the famous router brands - Linksys, Cisco, Netgear, Apple AirPort, SMC, D-Link, Buffalo, TP-LINK, 3Com, Belkin. Now we will start our mission: router rescue
No.1. Change your router password
Once you are logged in to the router's settings page, the first step is to change your router's "default password". Go to the Administration settings on your router's settings page and change it. This way, your wireless router will be more secure. Hackers are smart, so they get the default username and password of the router using the public database on the internet.
Just like a DLink router, anyone can change the settings of your router using its default username and password, which is the admin ... so changing the default values makes your router more secure.
No.2. Rename your SSID (Service Set Identifier) wireless network
The SSID of your wireless router is usually predefined as "default" or set as the brand name of the router (e.g., D-Link). Even if it doesn't make your network more secure already, it's a good idea to rename your network's SSID because it lets them know what network they're connecting to (like "My Social Services," "Doraemon" funny a ) Do not use personal information in SSID name such as your name, home address.
These settings are usually under the basic wireless settings on your router's settings page. Once this setting is done, you realize that you are on the right road to the right house, you are connecting to the correct wireless network.
Beware of Wi-Fi thieves, rename the network. Hackers create free Wi-Fi scanning tools like Interider (Windows) and Kismet (Mac, Linux). These devices allow anyone to find all available wireless networks in the area, even if the router does not transmit their SSID name.
No.3. Enable network encryption
To prevent other computers in the space from using your Internet connection, encrypt your wireless signal. There are many encryption methods for wireless settings, including WEP, WPA (WPA-Personal), and WPA2 (Wi-Fi protected version X version 2). WEPA is the necessary encryption and, therefore, the least secure. It can be easily cracked. So WPA2 is the safest
To enable encryption on your wireless network, just open the wireless security settings on your router's configuration page. This usually allows you to choose which security method to choose; If you have an older device, select WEP, otherwise go with WPA2. Enter a passphrase to get access to the network; Make sure others find it difficult to guess, and just consider using a combination of letters, numbers, and special characters in a code phrase.
Hackers or thieves use some free tools like code strips and crack non-hackers using WEP / WPA (PSK) using a dictionary or brute force techniques. What you should know is that Wi-Fi encryption can be easily broken using an AirCrack (a free tool like CodeWP strips) with a broken iPhone.
No.4. Filter MAC address
Just as every computer connected to the internet has a unique IP address, so all your wireless devices have an individual MAC address. Remember one thing that Paul Mac has a different concept. Add MAC addresses of your devices to the settings of your wireless router with the added layer of protection to connect only the specified device to your Wi-Fi network.
MAC addresses are hard-coded in your networking devices, so one address only allows one of those devices on that network. The worst truth is that Macs can cheat addresses. But the beautiful thing is that this can only happen if the thief knows the MAC address of the computer connected to your wireless network.
To enable MAC address filtering, you can enable MAC address filtering only after you have listed all the hardware devices you want to connect to your wireless network. Find their MAC addresses and add them to the MAC address filtering in your router's administrative settings. Then simply open a command prompt and type "ipconfig / all" to find the MAC address for your computer so that your MAC address appears next to the "physical" address. Although different for each device, you can find MAC addresses of wireless mobile phones and other portable devices in their network settings.
What happens is someone or a hacker, or you call a thief, changes the MAC address of his or her computer and allows your network to connect to the device with that particular MAC address so it can easily connect to your system. Anyone or thief fixes the wireless MAC address of your device wirelessly using a sniffing tool like NMAP and then changes the MAC address of their computer using another free tool like MAC Shift.
No.5. Reduce the range of the wireless signal
You can change the mode of your router to either 802.11g (instead of 802.11n or 802.11b) or use a different wireless channel. Restrict the direction of signal researchers who have developed a unique Wi-Fi blocking paint. Apply anti-Wi-Fi paint. The chemicals in the paint absorb radio signals.
Coating the entire room, Wi-Fi signals can't come in and, importantly, can't go out. This allows you to prevent anyone outside the home from accessing your home network without setting up encryption at the router level.
No.6. Upgrade your router's firmware
Sometimes when you check the manufacturer's site, you realize that your router is not running the latest firmware. You can find the current firmware version of your router using 192.168 from the router's dashboard. Connect to your secure wireless network. Filter MAC addresses with WPA2 (AES) encryption (and complex passwords) to secure your wireless network.
You do not need to enter SSIDs, passwords, and other information every time you connect to the internet as you need to add new settings to your computer and other wireless devices so that they can all relate to Wi-Fi networks.
You can choose to let your laptop connect to this network automatically. Don't worry. The wireless network will be much safer now. And if you are still worried..! Turn off the router entirely, then the system will go, and the thieves will also go. Your electricity will be saved and even a pumpkin for wireless thieves.
