Wifi Router Setup Guide

Where Does This IP Take Me?

When a particular application tries to connect to a particular device for internet use, they use the port number (22 for ssh) that is well known for a particular application, along with the IP of the device to which it wants to connect.

When you enter the router’s default IP into the web browser, you will see that the browser will forward the HTTP request to the router on port 80 or 443.

At the point when the solicitation is gotten on the router on the ports over, a little web server running will satisfy this solicitation. The appropriate response is the site page we see.

Ethernet Connection

This is translated into an IP address managed by the web server in a location similar to the working principle of each website.

The only difference is that the web server is running inside the router.

To give an example, consider a Wi-fi router running the Openwrt operating system. The web server used for web login must be uHTTPd. uHTTPd is a system that has been developed for a very compact and less resource gap, especially because routers have less processing power and memory limitations. Each router manufacturer also has its own lightweight web servers, which are often registered.

Why So Many Different IP Addresses?

Different router manufacturers must have different default IP addresses, and most begin with 192.168.x.x or 10.x.x.x.

It is called all IP-specific addresses that we include in our network, but these network addresses are not unique in the world. You can have 192.168.1.2 IP in your home and your neighbor can use the same IP without a problem in the home network. Here are the IP addresses that are allowed for private use:

10.0.0.0 - 10.255.255.255

172.16.0.0 - 172.31.255.255

192.168.0.0 - 192.168.255.255

Manufacturers can use any address in the above IP address range in their routers’ software to provide network addresses. Some manufacturers use the 192.168.x.x series, some come with the 10.x.x.x series. For the rest of the network, it is dynamically supplied from the DHCP server at the same subnet address as the IP router.

If the default IP address of the router you use is 192.168.1.1, the IP address of your devices on your network will probably be in the range 192.168.1.2 to 192.168.1.244.

In the past, custom addresses were divided into classes, and each class had different host numbers available; for example, IP addresses starting with 10.xxx were class A addresses and could handle a maximum of 16777214 hosts. It’s a huge figure, even for a small-scale company. The 172 series can handle up to 16384 hosts. And 192.168.x.x up to 254 hosts.

We mentioned above three special address classes, class C – 192.168.x.x, which makes the most sense for home use, because 254 hosts are more than enough for home use. With CIDR (Classless Cross-Domain Routing), we can create IP blocks with any number of hosts; However, most home routers still depend on the 192.168.x.x IP today. (192.168.1.1, 192.168.1.100, 192.168.0.1, etc.)

In addition to using IP, manufacturers also have URLs to log in to the router, for example in case of TP-Link brand routers, help is available at http://tplinkwifi.net.

Login Credentials and Security

If you looked at the login information of your router you purchased a few years ago, you will see a login that is described as quite simple:

On the other hand director, something like 1234; The secret word was mentioned to be changed during the arrangement procedure. Nonetheless, there are numerous gadgets with default contributions to the wild.

The default information in the user and password section used to access the router settings causes a serious security vulnerability.

Anyone who knows the brand and model of the router can access this information and log in to your router. This makes the router prone to malware and many attacks, which means it is vulnerable.

Username: admin

Password: admin

Producers have thought of arrangements that are more secure than the fixed login certifications, for example, special default login passwords for every gadget, shipping gadgets without any password and make password setting obligatory during the arrangement procedure.

We try to provide manufacturers with a unique password, but we also face situations where they cannot provide a secure login password. An example of this is TP-Link, which sends WR702N devices with the input password extracted from the router’s MAC address; this means that MAC addresses are broadcast in each packet and can be easily obtained by everyone in the physical coverage area of your Access point, which could be a vulnerability.

So it’s in every case better to change the default passwords despite the fact that the login data is one of a kind.

Please remember to check your router WEB access from time to time and change your password frequently.
