This table provides a quick reference for your router's speed limitations, real-world Wi-Fi vs wired speeds, and ISP speeds.
| Category | Advertised Speed | Actual Real-World Speed | Wired Ethernet Capability | Notes / Bottlenecks |
|---|---|---|---|---|
| 802.11g Wi-Fi Router (54 Mbps) | 54 Mbps | ~20–25 Mbps | Typically 100 Mbps | Wi-Fi is the bottleneck; wired is much faster. |
| 802.11g Wi-Fi Standard | 54 Mbps | ~20–25 Mbps | 100 Mbps | Standard limits Wi-Fi only, not wired ports. |
| "100 Meg" Internet from ISP | 100 Mbps | ~90–100 Mbps | 100 Mbps supported | Wi-Fi cuts this to ~20 Mbps on 802.11g routers. |
| 100 Mbps Ethernet (Fast Ethernet) | 100 Mbps | ~94 Mbps | N/A | Wired avoids Wi-Fi limitations. |
| Gigabit Ethernet (if available) | 1000 Mbps | ~940 Mbps | N/A | Requires a router with gigabit ports. |
