A Local Area Network (LAN) and Wireless Local Area Network (WLAN) are computer networks that connect several computers and peripherals in order to allow several users to share and utilize a common Internet connection and resources. Due to standardized plug-and-play features of modern computers and peripherals, creating a company’s network is faster than ever. However, consulting with an IT support expert is advisable to ensure proper deployment and security, especially for complex systems.

Needs Evaluation

Prior to commencing a network setup, evaluate your company’s needs because they will have a significant impact on the network’s configuration and equipment. The following are important factors to consider:

• Number of networked computers and peripherals
• Types of data and files shared and stored
• Types of applications
• Remote access
• Mobile device usage
• Wired and wireless usage

In the advent of networks, computers and devices were only connected by cables. Nowadays, wireless networks have become most common in the workplace because of accessibility and flexibility they offer for mobile devices.

Despite the need for cables, wired or Ethernet networks are faster and more secure than wireless networks. In addition, wireless networks are more susceptible to dropping a connection if the number of devices exceeds capacity. Electronic interference also affects wireless connectivity.

Most businesses utilize both wired and wireless configurations in their networks. However, cables are predominantly used for connecting important devices and peripherals to ensure reliable connectivity.

Necessary Equipment

The basic components of a network are a wired/wireless router and a server or a computer that acts as a server. However, cloud-based servers are becoming more common because of the security and scalability they offer.

Typically, consumer routers are compatible with the IEEE 802.11ac wireless networking standard and offer several Ethernet ports, wireless encryption, and a built-in firewall. Business routers provide advanced features such as intrusion detection, anti-spam and anti-virus, greater firewall control, network traffic filtering, and virtual private network (VPN) capability for remote access.

Company Network Security Steps

• Replace default password with new one that is long and complex.
• Activate firewall and adjust to suitable settings.
• Activate wireless encryption.
• Activate VPN to enable remote access.
• Limit network access to authorized users through network logins and passwords.
• Select secure passwords and revise regularly.
• Create secondary guest network with a distinct password revised regularly.
• Install security software.
• Physically secure the router to protect its security settings.
