How to set up a Wi-Fi network

 The Internet is a really powerful tool. It gives us access to all kinds of information at any time, for example, email, Google search, and Wikipedia. So there is something a bit of a contradiction about the fact that you can only use the internet when you are sitting at your desktop computer. What if you could use the Internet from anywhere in your home or office?

If you already have a high-speed (broadband) Internet connection at home, setting up your home wireless network is easy. A wireless network, commonly known as wi fi management, allows laptops, smartphones, and other mobile devices to connect to a home Internet service without an Ethernet cable.

To create your own Wi-Fi network, you need a wireless router. This is a device that will transmit the Wi-Fi signal from your Internet connection throughout your home. Your Internet Service Provider (ISP) can offer you a wireless router for a small monthly fee. If you've never set up a Wi-Fi network before, this might be the easiest option.

If you are looking to buy your own router, we recommend that you spend a little more time exploring the different options. CNET offers a comprehensive guide on how to buy a router.

1. Once you have purchased a wireless router, you need to connect it to your existing internet modem.
2. Connect an Ethernet cable from your modem to your wireless router (a short Ethernet cable is usually included with your wireless router for this purpose).
3. Connect the power cord to your wireless router.
4. Wait at least 30-60 seconds and verify that the LEDs on your router are working properly.

Configure your router

You will then need to use your computer to configure the default router settings. This includes setting a unique username and password for your wireless network.

1. Using a web browser, enter the default IP address of the router in the address bar and press Enter. Your router's instructions should include this information, but some of the more common addresses include 192.168.0.1, 192.168.1.1, and 192.168.2.1.
2. The router's login page will open. Again, the precise login information should be included in your router's instructions, but most routers use a standard username and password combination, such as administrator and password.
3. Your router's configuration page will open. Find and select the Network Name option, then enter a unique name for the network.
4. Find and select the network password option and then select the encryption option. You can use various types of encryption, but we recommend WPA2, which is generally considered the most secure.

Connect!

That's it! Now you are ready to connect to your Wi-Fi network and verify that it is working. The process for connecting to a Wi-Fi network will vary slightly depending on the type of computer or device you are using, but any system will require these basic steps.

1. Find your computer's network settings and look for nearby Wi-Fi networks.
2. Select your network and enter your password.
3. If the connection is successful, open your web browser and try going to a web page like www.google.com. If the page is loading, it means that your Wi-Fi connection is working properly.

Is Network Engineering a Good Career?

 Network technicians create, plan, and manage networks to ensure they are working and optimized. As a network technician, you are responsible for the overall foundation of a company's IT system.

IT administrators and network technicians are the people who help network technicians solve problems on a daily basis and face the great challenge of improving and shaping networks. Depending on your organization, you are responsible for implementing and building wireless and physical networks, as well as for troubleshooting, integrating, and researching new technologies.

Is network engineering a good career?

The demand for candidates for network technicians in the IT sector is increasing dramatically, while the supply is very low.

 Companies are now looking for network technicians as new networks and systems become more difficult and complicated as technology advances. Depending on the position and organization you work for, you may only be working on a few projects as a entry level network engineer.

 

Projects you can work on

Some of the projects you can work on are:

Computer network maintenance: Engineers in this area make sure that resource sharing and communication works between devices like servers, printers, and computers. It is your responsibility to ensure that connections with interruptions and limited downtime are fast. It is also responsible for interacting with other users and providers, for example. B. Internet service providers to maintain the entire network.

Implementation Management: Network engineers are responsible for managing the implementation and taking on the role of project manager for IT related projects. His goal is to take over the entire implementation and management of all IT projects.

System Design: These project staff are responsible for developing a network design and taking into account all physical budget and building designs. If there are multiple infrastructure buildings, a network engineer must be able to design a network called a wide area network for the organization.

Stay up-to-date: To stay up-to-date with the latest technologies, network engineers must stay up-to-date and be able to maintain networks and learn about the latest company technologies.

Since there is a great need for network technicians on the market and the properties for a specialist's qualification are lacking, the possibilities are great. Having a role as a network technician can be lucrative and exciting as a career choice.

Network Systems Security Engineer Risks

 Enterprise network engineers have a wide variety of system security risks. In the perfect world, security risks are mitigated before security breaches occur. Network design, user account management, and a well-defined process help minimize the potential for security breaches. Network engineers must be vigilant and alert to unexpected intrusions. The risks that entry level network engineer must mitigate include unauthorized network access, cyber attacks, cloud computing issues, and employee behavior that pose a security risk to the network.

Wireless Intrusion

Wireless networks are vulnerable to some possible infractions. Enterprise Wi-Fi networks should not implement WEP security because WEP encryption is not as robust as other options like WPA. Wireless networks are also at risk of man-in-the-middle or MITM attacks, where an intruder can hijack user sessions. MITM attacks are also known as frame forgery. Risk experts also recommend implementing WPA security to reduce the risk of this type of attack. Additional recommendations include configuring and updating your network's virus protection.

Dissatisfied And Poorly Trained Employees

Employees can be a risk to network security, and for disgruntled employees, the risk is exponential. An unfortunate or poorly trained employee, whether or not an individual is actively involved in a security breach by hacking a fraudulent domain or simply providing unauthorized users with login credentials on the network. Personnel can open the network to various security risks. Network design and user management policies should limit access to only the files, folders, and servers that employees need to do their jobs. Also, user accounts should ideally be disabled before or immediately after an employee leaves the company.

Cyber ​​Attack

Cyber ​​attacks are a risk to any business, large or small. Cyber ​​attacks differ from common malware infections on computers in that the company's network is specifically aimed at intrusion or elimination of denial of service. Cyber ​​attackers can use a combination of tactics to enter the network, including the use of malware, hacking, and social engineering, such as luring one of the company's employees to provide corporate information. Well-designed secure networks and trained users are the engineer's best protection against such cyber attacks.

IT Consumerization

"Consumerization of IT" refers to the practice whereby employees connect personal devices such as tablets and smartphones to the corporate network. This approach not only uses the company's resources, but also poses a significant security risk. Experts recommend that network engineers establish corporate policies regarding the use of networks for unauthorized devices and help use network monitoring tools to identify unauthorized devices connected to the network. I am.

Cloud Computing

One of the biggest challenges facing system designers and engineers is integrating cloud computing security into their existing infrastructure. Whether you're using software as a service, or "SaaS" products, or deploying commercial cloud storage at the enterprise level, more and more companies are moving in some way to cloud computing. Cloud computing poses risks to network engineers regarding security and possible data loss. IT executives and managers must take these risks into account when deciding whether cloud computing is feasible and secure for their business.

What Key Points Consider in a Managed LAN Service Provider?

 A managed local area network (LAN) service provider offers comprehensive LAN infrastructure management for small businesses, large campuses, and data centers.

In the past, companies managed their own LANs and even quickly recovered from disaster. But today, as networks continue to become more complex and technically complex, companies need outside help to take care of their local network.

Internal communication is critical to your business, and choosing a Managed Lan Services is key to ensuring uninterrupted service. These are the factors to consider before choosing a provider:

1. QoS and security

As demand for bandwidth and data rates continue to grow, a service provider must be able to provide quality of service (QoS) to prioritize certain applications over others. You should also pay attention to the security features included in the service. For example, some vendors offer network mapping and auditing, IP security encryption, and user-based authentication.

2. Coating

An ideal ISP should have a large number of LAN ports for its existing customers and manage local corporate networks from its own data centers through secure connections. It is also useful to ensure that they provide managed LAN services in accordance with the Information Technology Infrastructure Library (ITIL).

3. Flexibility

The provider must customize its services to suit your business needs. Also, make sure the vendor offers its own hardware. This saves you the burden of investing in internal IT infrastructure and frees your IT team from the responsibility of managing the corporate network. However, the provider must allow you to use your own hardware if you wish.

4. Personalization and maintenance

The ISP must provide initial configuration of the LAN ports, management of associated hardware and software, and hardware maintenance and implementation. You must proactively monitor and report on SLA compliance, technical metrics, and updates.

5. Support

With increasingly diverse business structures, cloud computing, and big data, LANs are far more complex than ever. As a business with many LAN ports, it can be extremely difficult for you to effectively manage your network and eliminate any unplanned breakdowns. This is why it is so important to have a team of experienced experts available 24 hours a day, 7 days a week.
