THE IP ADDRESS 19216801 - 188.8.131.52
THE STANDARD ADDRESS ON ALMOST ALL ROUTERS
To be able to connect to the Internet, you need to use devices called Routers. Routers allow a "dialogue" between different networks, in our case between the Internet and our local area network. Routers can be either Wireless (without Ethernet cable) or Wired (with Ethernet cable). Almost all of them use the IP address 184.108.40.206 to connect to the network.
A router is a layer-3 device of the OSI (open systems interconnection) model that is responsible for routing, or sending, data from one network to another network. The router uses a routing table that resides in its memory to determine the networks that the router knows how to send data to.
How to do this ?, On your computer, you have to set the IP address to 192.168.0.2 (you can choose the last numeric value in a range between 2 and 254) and the Netmask to 255.255.255.0. This way your PC can communicate with the Router since both devices are in the same address class. PC 192.168.0.2 -> 192.168.0.1 Router. To verify that everything is fine, open a DOS window using the CMD command prompt and type PING 192.168.0.1. If you get an answer, it means that everything is ok. Once you have done this, you need to open a browser (such as Chrome, Firefox, Edge, etc.) and type in the address bar the value 192.168.0.1. Subsequentially, you should see the configuration screen of the router; Now you must know the configuration parameters that you have obtained from your Internet provider and set them in the corresponding fields. You can also follow the steps shown in this video guide 220.127.116.11 Wireless Router
CISCO's router differ from SOHO ones, it is possible to configure the this class of router via telnet. example: telnet 192.168.1.1 after that user and password are requested to access the system. Cisco's Router are much more difficult to be configured and requires special knownledge
WHICH FREQUENCE I MUST USE 2.4 GHZ OR 5 GHZ ?
The primary differences between the two frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.
The range is lower in the 5 GHz band because higher frequencies cannot penetrate solid objects, such as walls and floors. However, higher frequencies allow data to be transmitted faster than lower frequencies, so the 5 GHz band allows you to upload and download files faster.
Your WiFi connection on a particular frequency band can also be faster or slower because of interference from other devices. Many WiFi-enabled technologies and other household devices use the 2.4 GHz band, including microwaves and garage door openers. When multiple devices attempt to use the same radio space, overcrowding occurs. The 5 GHz band tends to have less overcrowding than the 2.4GHz band because fewer devices use it and because it has 23 channels for devices to use, while the 2.4GHz band has only 11 channels. The number of channels that are available to you depends on the regulatory domain. If you're experiencing a lot of interference from other devices, consider using the 5 GHz band.
DEFAULT USER AND PASSWORD
USERNAME AND PASSWORD OF MAIN ROUTERS FOR HOUSE OR SMALL OFFICE
Don't forget to change the username and password of your router's control panel. A good rule is to use passwords that are complex enough to be difficult to guess..
TIPS TO REMEMBER TO CHOOSE THE PASSWORD
NEVER leave the Default Password
Do not use a Password equal to the Username
Do not use a Password equal to your date of birth
Do not use your First or Last Name as a Password
Do not use your PET name as a password
Do not use a numeric password
The Password must contain at least a capital letter, a number and a special character. For example : MyPa$$word2018
The Password must have at least 8 characters
These rules ALWAYS apply when creating a Password. Please avoid using the same password for all services, for example, the password for accessing your home banking must not be the same as the password for accessing a forum.

WHAT IS A NETMASK - DOWNLOAD THE IPV4 CALCULATOR FOR FREE IPV4
If you always have wondered what netmask is and what it is supposed to do, I am going to explain it to you in the easiest way possible :) Once you open the control panel of your router, you can read two values, its IP address 22.214.171.124 and Netmask 255.255.255.0. If you notice, these two numeric notations are made up of 4 digits separated by decimal points.
Now before proceeding, we shall rewrite the 4 digits in binary format and obtain 11111111.11111111.11111111.00000000. As you can see, now we have transformed the decimal "255" into binary, resulting in 11111111 while the 0 has become 00000000.
So what is a Netmask? It is merely the number of network devices that can be used :) How do you calculate it? The formula is 2^(elevated to the number of zeros)-2
So 2^8-2=254 here is the number of network devices that can be used. The 2 addresses that cannot be used are 192.168.1.0 (the network identifier) and 192.168.1.255 (the broadcast address), instead, the addresses that can be used range from 126.96.36.199 to 192.168.1.254
The 1s represent the number of networks.
188.8.131.52 HOW TO USE THE NETMASK
HOW TO USE THE NETMASK - PRACTICAL EXAMPLE OF USING THE NETMASK
We have understood in the previous paragraph what a netmask is; now we have to see how it is used and when it can be useful.
Let's start by saying that usually at home we do not need to use the netmask differently from the usual one (usually you simply leave the default value: 255.255.255.0), but let's consider the following problem. You receive a 192.168.1.0 IP address class, and you are asked to create 6 subnets (perhaps 1 per classroom) each of which must contain 30 PCs.
In this case, the netmask comes into play. This operation is called SUBNETTING.
We have seen that the netmask 255.255.255.0 is equivalent to 11111111.11111111.11111111.00000000, now we have to use the last octet, 00000000, to be able to manage the required 6 sub-networks. To represent 6 subnets, we need 3 bits because 2^3=8, this means that among the 8 bits available we need to use 3 bits, therefore, the last octet shall be converted into 11100000
If we transform 11100000 to decimal places, we get 224. Hence the new netmask 255.255.255.224 allows you to manage the 6 required subnetworks, but for each subnet, how many PCs can we manage? Out of the 8 bits set to 0, now 5 are currently wasted. From here we can deduce that we can manage 2^5-2=30 PCs for each subnet. Keep in mind that when subnetting, not all 254 IP addresses may be used.
