免费没有花钱的香？装宽带送了WiFi光猫，为什么还要接路由器？

Core Viewpoint - The article discusses the limitations of using an optical modem (光猫) with built-in WiFi capabilities compared to dedicated routers, highlighting the need for additional routers to ensure stable and high-performance wireless networks [1][14]. Performance Differences - Optical modems are primarily designed for converting optical signals to electrical signals, which limits their hardware resources for WiFi functionality, resulting in poor performance under high load [3][5]. - Dedicated routers are designed for wireless coverage and data processing, equipped with powerful processors and larger memory, enabling them to handle multiple high-bandwidth tasks simultaneously [5]. Functional Limitations - Optical modems have a simple interface and limited network management features, making it difficult for users to manage their networks effectively [7][9]. - In contrast, dedicated routers offer advanced features such as Quality of Service (QoS), parental controls, and device management, catering to diverse user needs [9]. Stability Issues - The stability of WiFi from optical modems can be compromised due to heat generation and resource sharing with other functions, leading to signal instability and disconnections [10][12]. - Dedicated routers have independent hardware designs and better cooling systems, ensuring stable performance and minimizing interference [12]. Security Protection - Optical modems have basic security settings that may leave networks vulnerable to attacks [13]. - Dedicated routers provide comprehensive security features, including advanced encryption methods and firewall capabilities, enhancing overall network security [13]. Conclusion - Despite the convenience of built-in WiFi in optical modems, their performance, functionality, stability, and security shortcomings make dedicated routers a better choice for modern home networking needs [14].
