The connection speed isn't matching what the router claims.
Hello everyone, I'm using a Huawei HG658c V2 router with an Asus Rog Strix B450-F MOMO. I expected around 75 Mbps, but the router shows 78 Mbps, which is fine. My PC gets about 64 Mbps, which isn't ideal. Speedtest reports 55 Mbps, and I've checked my updates, including the BIOS. I'm not sure what's going on. I suspect a significant drop at the down speed, but my ISP says everything looks normal from their side. They mentioned sending a team to investigate and saying no issues were found. I have limited knowledge of Ethernet or electrical aspects, and I'm unsure about the big Ethernet device in my building. I'd really appreciate help figuring this out.
What rate are you charging for internet service? Which speeds are available with a wired connection? Make sure Wi-Fi isn't being considered as an option.
Your internet connection is working properly. The modem connects to the ISP at a speed of 64mbps down and 8mbps up, which determines the bandwidth available. You can expect roughly 58mbps for downloads, with about 90% efficiency during transfer. Uploads are around 93% efficient. Everything looks good.
It's not a serious issue, but you're welcome to voice your concerns. However, the wiring in your home could also be the cause.
There’s no such concept as "90% efficient download speed." It isn’t related to a power supply. When using networking, if your maximum down speed is 75mbit, you should expect around 75mbit down. There’s no standard saying "90% is sufficient" or similar. If you’ve already checked wifi: it’s time to inform your ISP they need to improve that speed immediately. Also, I have VDSL too and sometimes it behaves oddly, dropping to about 60% of my usual rate for a few days, then returning to normal. This might be happening in the same situation.
Your argument highlights a clear distinction between energy conversion in physics and data transfer rates in networking. Efficiency refers to how well energy is transformed, not the actual speed of data movement. It's incorrect to equate 100% efficiency with achieving the full advertised speed, just as assuming a car's top speed means it can only go 180 km/h at 90% efficiency ignores the real performance. The two concepts are unrelated.
You reside in an ideal environment, employ iperf on your local network, and I’m confident you won’t achieve the claimed speed. Try it and share the outcomes here. Nothing functions at full efficiency, a concept that extends beyond science to human affairs—like HR departments assessing employee performance. https://dictionary.cambridge.org/diction...efficiency efficiency noun [U] The optimal utilization of time and resources without waste. What stands out about their society is the high efficiency of public services. Energy efficiency in physics refers to the balance between energy input (fuel, effort) and output (movement). More instances: She excelled at her tasks with remarkable speed and precision. Optimizing car design boosts fuel efficiency. Eight navies will participate in a Pacific exercise aimed at enhancing combat efficiency. He strictly values efficiency. Sweden has demonstrated the path forward in energy efficiency.
You notice the advertised speed isn't always what it seems. The claimed rate should reflect your actual efficiency. If their service only delivers 64Mbit, they should clearly state that instead of a higher number. As a buyer, you can't just accept "well, 90% is fine" when the price reflects the real performance. What determines this percentage? Why not 95 or 70? This inconsistency is what bothers me. It's similar to car specs—like seeing "140HP" on a sheet, but knowing it only provides 33% efficiency means the true power is much lower. That wouldn't be fair.
The issue isn't about reaching a perfect 100% speed on a direct connection. It's mainly due to extra processing and how devices manage that data (visible or not). With a solid point-to-point link through a switch that supports full speeds, you'll see the complete line rate—provided both ends have compatible NICs. The difference often lies in how the app accounts for overhead. If you're sending many large packets along with Ethernet headers, the display might remove the header information, making the actual speed seem lower.
