家里网速不对劲？可能是这些原因造成的！

Core Viewpoint - The article discusses common issues affecting home internet speed and provides solutions to optimize WiFi performance. Group 1: Understanding Internet Speed - Home broadband speed is often advertised in Mbps, while download speeds are measured in MB/s, with the conversion being 1 Byte = 8 bits, meaning a 1000 Mbps connection theoretically allows for 125 MB/s download speed [1] - Various factors can affect actual internet speed, including physical losses, signal attenuation, and device performance [1] Group 2: Common Issues and Solutions - Outdated Equipment: If the broadband speed exceeds the capabilities of the modem/router, it can slow down the internet. Upgrading to compatible high-speed devices is necessary after increasing broadband speed [2] - Router Placement: WiFi signals can be obstructed by walls and electronic devices. Placing the router in a central, open location can enhance signal distribution [3] - Frequency Band Selection: Dual-band routers offer 2.4GHz and 5GHz frequencies. The 2.4GHz band has better range but lower speed, while 5GHz offers faster speeds but shorter range. For optimal performance, 5GHz should be prioritized when conditions allow [4][5] - Cable and Device Compatibility: Different types of cables support varying bandwidths. For instance, category 5 cables are suitable for speeds up to 100 Mbps. Upgrading to higher category cables may be necessary when increasing broadband speed [6] - Excessive Connected Devices: With multiple devices connected, bandwidth can be consumed quickly. Managing device bandwidth through router settings can help alleviate slow speeds [7] - Unauthorized Access: Weak WiFi passwords can lead to unauthorized access, causing slow speeds. Strengthening passwords and hiding the network name can prevent this issue [8] - Network Setup: Single routers may not cover larger homes effectively. Custom network solutions may be required for comprehensive coverage in larger spaces [9]
