WiFi is slow and stuck, maybe it’s a traffic jam

The NBA Finals are coming! But when using WiFi to watch the game, do you often encounter buffering and lag? Such a phenomenon is particularly annoying. How can it always lag at the critical moment? In fact, this has a lot to do with the adjustment of our team's WiFi. Especially now that every household has a lot of wireless devices, there is a phenomenon of "co-frequency interference" between them. When there is mutual interference, the user's Internet access will become slower.

How can we get stuck at the critical moment?

When you surf the Internet at home, you often feel stuck, the speed is slow, the video is always buffering, the wireless signal strength fluctuates... If you encounter the above situations, it is likely that the wireless channel is too congested, causing a traffic jam in the wireless network. The selection of wireless channels for wireless networks is a point that home users often overlook. It is like the lanes marked on the ground when we drive on the road. Data and information are transmitted to the wireless network card and wireless router on these "lanes".

Wireless channel division

As we can see from the above figure, there are 13 channels commonly used in the 2.4GHz frequency band. Users can switch them in the background management of the router to select the most unobstructed wireless channel. If there are some wireless devices in the home, such as wireless headphones, wireless keyboards, wireless mice, and microwave ovens that are being turned on, they will also cause certain interference to wireless transmission. So, how to avoid congested wireless channels and choose unobstructed wireless channels also requires some tips.

Select a clear wireless channel

Nowadays, most residents have deployed wireless routers in their homes, and conflicts in channels are inevitable. When we find instability or jamming when using the network, we might as well switch to a channel with fewer access points. For example, in the Ji Router client, users can use the "WiFi" traffic function to check the congestion level of each channel, which is convenient for users to switch to idle channels and enhance wireless signals. You can also use the "wirelessmon" software to check the status of wireless channels, and users can switch channels in time.
