Diagnose Wi-Fi performance issues
I'm looking into why my ISP isn't delivering the speeds I'm paying for. I pay for 600mbps but consistently see only 200mbps or less on SpeedTest.net, usually between 150-180mbps. I've checked the network adapter in Windows and confirmed it's reporting the correct speed, so the problem seems to be on my side. What steps can I take to improve performance? I'm fine with 200mbps, but I want to avoid paying full 600mbps when I can realistically get less. My system specs include Intel 4790k, Asus Z97-Deluxe, 16gb RAM, G.Skill RAM, Nvidia GTX 780, and a Netgear CM1000 router with an Nighthawk AC1750 modem.
Your connection speed is limited by your current hardware. At 2.4GHz you typically cap around 250 Mbps, even near the router. For better performance, switch to a 5GHz network to reach speeds closer to your ISP.
I'm linked to the 5GHz network. The router supports 2.4GHz, 5GHz, and a guest 5GHz network. I'm fully connected to the 5GHz network.
Is this speed test displayed here using the modem or router? Have you checked speeds when connected directly via Ethernet? Do you see any variation? Are there other devices downloading on your network during these tests? Is your computer running any background downloads?
The testing is being carried out via WiFi because that’s the setup my computer uses now. Unfortunately, I lack a sufficient cable length for a wired connection using Ethernet. Although the PC is only about 15-20 feet from the router, I still expect the advertised speeds to be achieved. WiFi might introduce some loss due to hardware limitations, making 200 Mbps seem too low for a 600 Mbps plan. Regarding other devices, I shared the same concern. I relocated everything except my PC to the guest network with 5 GHz and connected only my PC to the main network. This adjustment increased speeds by roughly 10 Mbps, which isn’t a significant improvement.
It isn't always a hardware issue; interference might be the cause. How many walls or floors separate the computer from the wireless router? Are there other devices or electronics along this route? Run WiFi Analyzer, and capture screenshots of the ‘Analyze’ page for both 2.4GHz and 5GHz bands.
Removing the attached image immediately due to the inclusion of your public IP address. Reconfirming the request: the focus is on the wireless connection rate inside your residence. SpeedTest evaluates the connection from your modem to an external server over the web.
