A LAN (Local Area Network) is a local computer network that allows communication between devices in a specific area, such as an office, home, or business. A WLAN (Wireless Local Area Network), on the other hand, is a wireless local network that allows devices to connect without using cables, using Wi-Fi technology.

The use of WLAN offers greater user mobility, elimination of the need to use cables, easier installation and expansion of the network, as well as the ability to access the network from anywhere within the range of the Wi-Fi signal.

• Computers and end devices (e.g. laptops, smartphones, printers)
• Router or network switch
• Ethernet cables
• Network sockets (RJ-45 sockets)
• DHCP server (for assigning IP addresses)
• Firewall (network security)

Yes, there are different types of WLANs. The most popular are 802.11b, 802.11g, 802.11n, 802.11ac, and 802.11ax (also known as Wi-Fi 6). The differences between them include data transfer speeds, range, level of interoperability with different devices, and supported frequency bands.

• Internet connection bandwidth
• Network device performance (routers, switches)
• Wi-Fi signal range and quality (in the case of WLAN)
• Number of connected devices and network load
• Network configuration and optimization
• Network security measures used

• Wi-Fi encryption (e.g. WPA2, WPA3)
• MAC address filtering (which allows access to the network to be controlled based on unique hardware identifiers)
• Hiding the network name (SSID)
• Your own network password
• Using virtual private networks (VPNs) when connected to an external network

• Installing additional Wi-Fi access points (APs) in strategic locations
• Using signal amplifiers (repeaters) to repeat and strengthen the Wi-Fi signal
• Using mesh technology, which creates a uniform WLAN network with several seed nodes (mesh points)
• Using Powerline technology, which transmits the network signal via the electrical installation

Yes, there are some limitations to the number of devices connected to a LAN/WLAN. These limitations are due to the bandwidth of the Internet connection, the performance of network devices, and the load on the network. Therefore, it is important to plan and scale the network appropriately to ensure adequate performance.

• Poor or no network connection
• Slow data transfer speeds
• Wi-Fi signal freezes or drops
• IP address conflicts
• Network security issues

• Checking the cable and network connections of your devices
• Configuring routers and switches
• Updating the software of your network devices
• Using signal extenders or installing additional access points
• Diagnosing and resolving IP address conflicts
• Configuring appropriate network security

• Detecting and resolving network issues in real time
• Monitoring network performance, throughput, and load
• Managing network security and access control
• Monitoring and optimizing quality of service (QoS)
• Planning network expansion and scaling resources
• Ensuring network continuity by monitoring and responding to failures
