Address issues with speed limits on your Netgear Nighthawk device.
Netgear offers numerous routers branded as "Nighthawk." When the device that manages the connection becomes overloaded, it typically slows down. Before switching to pfSense, I had to adjust my routers and cables because they would throttle during long downloads due to heat buildup. A fan helps maintain steady performance. If speeds fluctuate—fast then slow—it might indicate cooling problems. For wired connections, poor cabling could be the issue; try different cables. With wireless setups, interference from nearby devices or channels can affect speed. Consider repositioning the router or checking for obstacles. It’s possible the network management is lacking. If you haven’t used a Netgear model recently, reviewing QoS settings might resolve the problem.
Many believe a router with Gigabit ports automatically offers Gigabit internet speed. That’s inaccurate. Gigabit ports are essential only for connections exceeding 100 Mbps. Upgrading to higher speeds requires the router’s SOC to handle NAT efficiently. A weaker SOC limits how fast the connection can operate. You need proper LAN to WAN and WAN to LAN performance. Most manufacturers don’t disclose these details. You might find relevant data on Smallnetbuilder.com, where they conduct tests, but you’ll need the exact Netgear model and search their site accordingly.
If the device is a high-end router, it likely attempts to manage QoS, which won’t work well on such a fast connection. It works best with slower networks. With Virgin, it’s more effective if you can limit uploads while allowing downloads. This is where you gain the most advantage and the router is more likely to handle it. I’m not comfortable with their interface to adjust these settings. Their gaming models try to auto-detect your speed and reduce it if needed, but this can fail if the speed test isn’t accurate—possibly due to a Goodput issue, which might be something to disable. If you can manually set your speed, you might set downloads to zero to only slow uploads. If you don’t mind that, just turn QoS off completely. If you rarely upload or aren’t gaming much, it probably isn’t necessary. I’ve been using Gigabit without QoS for a while now.
