1. Types Wireless network cards are mainly divided into internal and external types. Internal wireless network cards are usually installed on the motherboard of a computer and require opening the computer to install; while external wireless network cards are like USB drives and can be directly plugged into the USB port of a computer for easy installation. 2. Transmission Rate The transmission rate is an important indicator for measuring the performance of a wireless network card. Generally, the higher the transmission rate, the faster the network connection speed. The mainstream transmission rates of wireless network cards on the market are between hundreds of Mbps and Gbps. 3. Compatibility The compatibility of a wireless network card is also an important factor to consider. Ensure that the wireless network card is compatible with your device and the network environment, to avoid connection problems. 4. Signal Receiving Ability The signal receiving ability determines the connectivity stability and coverage of a wireless network card. High-quality wireless network cards have stronger signal receiving ability, able to maintain stable network connections at greater distances and in more complex environments. III. Purchasing Suggestions 1. Choose the Right Type Based on Needs Choose the appropriate type of wireless network card based on your usage needs. If you need to frequently replace devices or use on multiple devices, an external wireless network card is a better choice; if you are purchasing a new computer, an internal wireless network card may be a better option. 2. Pay Attention to Transmission Rate When purchasing a wireless network card, pay attention to whether its transmission rate meets your needs. If you require high-speed network connectivity, choose a wireless network card with a higher transmission rate. 3. Consider Compatibility and Signal Receiving Ability
