To stop your Wi-Fi from connecting to 2.4GHz, change the channel or use a different frequency band.
To stop your Wi-Fi from connecting to 2.4GHz, change the channel or use a different frequency band.
At first, my internet worked smoothly with my ISP. After a while, the speed fell from 300Mbps to just 4-5 Mbps. I discovered my Wi-Fi was using the 2.4 GHz band, which caused the slowdown. I had to switch it off and back on repeatedly. This keeps happening often. I’m wondering if there’s a way to stop my Wi-Fi from connecting to that frequency?
Which router are you using? Does it offer a setting to turn off the 2.4GHz radio? It seems like another source of interference might be present. The 2.4GHz Wi-Fi protocols can handle much higher speeds than that.
I'm working with Distributel and they're using the TP-Link Deco... I believe there might be some additional interference at play. The 2.4GHz WiFi networks can handle much faster speeds than what you're seeing. I share this concern too... initially I thought it could be due to too many devices online, but then I realized that's not the situation. Still, I'm unsure what caused the slowdown. As you mentioned, 2.4GHz standards are far more capable than what's happening here.
Probably some interference exists. Many devices operate on 2.4 Ghz, which is common. Besides typical uses like Bluetooth operating on the same frequency, numerous wireless gadgets rely on this band since it’s free as long as you adhere to guidelines. The 2.4 Ghz spectrum contains just 11 channels, with only three non-overlapping ones. This varies by router; if you can isolate the 2.4 Ghz and 5 Ghz bands into separate networks, connect accordingly. The main concern is the loss of the 5Ghz connection. WiFi tends to favor a more reliable link to the router over higher speed. The problem might stem from a weak 5Ghz signal, prompting a switch to a more stable connection. Higher frequencies generally offer less range and penetration, and distance from the router can slow the link—prioritize stability instead of speed.
It seems there might be more than 20 devices on the property. The speed drop appeared after setting up a Wi-Fi mesh system, which led us to add two extra Wi-Fi pods—one in the basement and another on the second floor. This increased the number of devices inside the house. I’m not sure if this is the exact cause.
The best method to link to your Wi-Fi on the 5 GHz band is to set up your mesh network with a distinct SSID for 5 GHz compared to 2.4 GHz. On a PC, Windows Hardware/Device Settings allows you to pick the network card and choose the 5 GHz option. If this doesn’t resolve the issue, you may need to diagnose your mesh system. Check if wireless mesh nodes aren’t hardwired and have poor links between them. Test Wi-Fi performance on the ISP modem/router directly connected. Wifiman for Android helps monitor signal strength. If the direct-connected node remains weak, the problem could lie with the mesh setup or a conflict between your configuration and ISP hardware. I’m unfamiliar with TP Link, but this outlines the typical troubleshooting steps.
