Issues with achieving maximum internet performance from your router.
Issues with achieving maximum internet performance from your router.
Hello everyone, I'm asking about router performance. My current model supports speeds above 300mbps, but when I connect directly from my modem to the router via Ethernet, it only reaches 950mbps. I've adjusted the bandwidth settings and set my IP to DMZ with priority, but it still caps even when I'm the only one at home. The router I'm using is a D-Link AC1900 Gigabit Direct. Is this issue common with older routers?
It could be related to older routers, and finding a similar model might help resolve the problem.
No QoS settings are enabled, firewall is disabled. Firmware appears outdated. Have you attempted a factory reset of the router?
Most routers don’t support Gigabit speeds, regardless of whether they have a gigabit port. The issue lies in the internal hardware not being able to handle Gigabit NAT, which explains why older models can reach over 300 Mbps. Generally, you won’t find Gigabit internet speeds delivered via WiFi—it’s unlikely. However, in certain setups you can disable QoS and other settings on some routers to achieve higher performance. For detailed comparisons, visit https://www.smallnetbuilder.com/ where they provide benchmarks for various routers. The key factor is the data path between LAN and WAN or vice versa.
I possess a "up to 555 mbps" plan from my ISP. On the wire connecting the router and PC it displays around 500-580 mbps. The Wi-Fi connection, however, is significantly slower—even on the 5 GHz band it’s roughly half the speed. The highest download speed I achieved was 397mbps and upload speed 401mbps, using a 5 GHz Wi-Fi card and a USB adapter with one antenna. I’ve found some articles suggesting that with high-speed plans, it’s acceptable to experience about 50-60% of the ISP’s maximum when using Wi-Fi. This applies to plans over 500 mbps. Numerous factors can reduce the signal strength from the router to your PC, such as distance, obstacles, or interference. Under ideal conditions you might get 80-90% of the speed, but this is uncommon. Of course, if your plan is around 100 Mbps or slower, you’ll likely maintain a stable 100 Mbps most of the time. This is the information I intended to share. Additionally, this subject interests me.
