Do router speeds matter?
Router speeds influence how efficiently data travels, but they don’t directly determine your actual internet speed. For typical home use, speeds around 15–30 Mbps are sufficient for basic tasks, while 100 Mbps is common for streaming and online gaming. Maximum theoretical bandwidth like 1200 Mbps isn’t practical for most users, so focus on reliable performance rather than peak numbers.
They still count. With a 100mbps internet link, you'd definitely need at least 100mbps WiFi and 100mbps LAN connections; otherwise, you wouldn't get the most out of your internet. For a NAS like mine, a 1 Gigabit LAN connection can be helpful. Faster Wi-Fi speeds are useful too if you plan to reach that NAS or any other connected device and move large amounts of data in or out.
The router accepts any internet link you possess (15,30,100mbps) and delivers it through both wired and wireless means. On wired connections, losses are minimal and performance matches the original connection—no delays, no data loss, consistent speed. With wireless, some delay occurs during signal conversion between air and the router’s internal processing. If many devices use the same frequency, latency may increase; distance from the router and surrounding obstacles can also affect performance. Generally, you should achieve 15 or 30mbps even with a weak wireless setup. A 100mbps connection might struggle on certain models, though most advanced routers handle it well. The theoretical upper limit shown on devices (like 1200mbps) represents the total bandwidth available for communication with connected devices. In reality, a 2.4ghz router can typically manage up to 300mbps at 300mhz and 866mbps at 5ghz, adding to about 1166mbps—rounded up for marketing purposes. The actual speed you receive depends on your wireless card’s capabilities, distance from the router, and any interference from nearby objects or walls. If your card supports only 2.4ghz, it won’t exceed its own max or the router’s 300mbps in that band. A 5ghz card needs dual antennas to reach up to 866mbps; otherwise, it might only deliver half that speed.
Rated speeds combine multiple frequencies. 5GHz @ 750Mbps 2.4GHz @ 450Mbps --------------------------- Total 1200Mbps. Achieving such rates is impossible due to current technology limits. A better-rated router may assist in certain scenarios, but generally success depends on a well-set network and minimal interference or overlapping SSIDs. Faster transfers are beneficial within your local network for peer-to-peer sharing. Your internet service provider's download capability is limited by their policies.
The router's speed refers only to the combined WiFi performance, not the actual achievable rate in practice. Real devices often lack sufficient antennas to reach full potential. For instance, a 1200Mbit router from one client might only deliver around 600Mbit, and the CPU could be strained, reducing broadband quality. This issue isn't about the broadband connection's capacity but rather its real-world WiFi capability, which is linked to the CPU's handling ability. Consumer routers generally can't reliably support 1000Mbit, especially when running WiFi simultaneously, as that workload can overload their processors.
