2.4 GHz Wi-Fi performs better than 5 GHz Wi-Fi on my computer.
2.4 GHz Wi-Fi performs better than 5 GHz Wi-Fi on my computer.
It's quite notable since you typically achieve around 4.5-5 Mb/s on 2.4 GHz but only 2.1-2.3 on 5 GHz. Coverage might be limited while the signal quality remains acceptable. What stands out is that Windows shows a consistent 135/150 Mbps connection, which aligns with the maximum bandwidth, yet actual speeds in 5 GHz often drop below 60 Mbps. I didn't see any significant improvement by choosing a different 80 MHz channel on the router for the 5 GHz band. Additionally, you're experiencing slowdowns on your phone, suggesting the 5 GHz network might be affected. Given that your ISP provides a fiber connection at 100 Mbps via Cat6, it seems the 5 GHz band could be a bottleneck.
Is the router located in a different area? Yes, it's quite typical. The 5GHz band performs better through walls compared to the 2.4GHz band.
The higher the frequency, the less it can pass through solid objects. Often I need to change from 5GHz near my router to 2.4GHz across the house. Still, with just one router and built-in WiFi, this could be fixed if I had more access points or a mesh network.
The issue lies with this router, preventing me from accessing wired speeds even when close to it.
Is this a new installation? What materials were used—concrete, steel, wood, drywall? Did you perform a wireless survey? Provide the channel outputs for both 2.4GHz and 5GHz.
Check if the RTX 3071 maintains stable WiFi performance across all devices at different distances. The problem might be limited to your main computer. If only your primary device is affected, modify its power-saving and transmit power settings. In Windows 10, navigate to Device Manager, select the WiFi adapter, and under Advanced, adjust MIMO Power Save Mode to "No SMPS" (default is Auto SMPS) and Transmit Power to "Highest".
Settings are standard except for the 5 GHz channel which is fixed at 104 and security uses WPA2 only. These adjustments didn’t resolve the issue. Physical barriers exist between the router and my room, though the router sits on a drywall section because Cat6 cables are being routed there.
None of my gadgets reach high-speed internet anywhere. The Wi-Fi performance isn’t consistent across other devices either—I usually see around 60-70 Mbps on my phone, peaked at 93 Mbps once but nothing more. The issue is that my PC consistently gets the slowest connections and never matches the speeds of others. I’ve adjusted many adapter settings without improving things.
It's notable that shifting my case forward significantly increased the speed:
