Section 3: How to Choose the Most Suitable Network Card Technology? 1. Analysis of Network Environment: First, analyze your network environment, considering factors such as your network speed requirements, mobility needs, and budget. 2. Determine Needs: Based on the analysis of the network environment, determine the type and speed of the network card you need. If your devices are in fixed locations and require high speed, a Gigabit or 10 Gigabit wired network card may be more suitable for you. If you need to use the network in a mobile environment, a wireless network card may be a better choice. 3. Consider Compatibility: Ensure that the selected network card is compatible with your operating system and other network devices to avoid compatibility issues that can result in reduced network performance or inoperability. 4. Brand and After-sales Service: Choose a well-known brand of network card to ensure quality and after-sales service. Additionally, understanding the supplier's after-sales service policy is also important.
