[Solution] Network aways congested according to the Network Optimization on the Deco app
This Article Applies to:
Deco with 1.5.x and higher firmware versions
Issue Description/Phenomenon:
Some customers may report that the Network Optimization feature on their Deco app always displays the network needs to be optimized even though the last optimization result was perfect minutes ago. This article aims to explain this issue.
1. Network Optimization on the deco APP keeps saying the network needs to be optimized.
2. An optimization has been done and the Deco app says the network is perfect. When triggering the optimization again, the result is still “need to be optimized”
Cause of the problem:
Network optimization would help Deco scan the available Wi-Fi channels and select the most empty channel automatically. After the first optimization, all the Deco nodes and all the client devices connected to the Deco network will switch to the new channel. While With all the Deco nodes and client devices attaching to this channel, it would be crowded again so the Deco app will show you the network needs to be optimized again.
Besides, whether the Wi-Fi channel is congested also depends on the network environment. For example, if you are streaming an HD video, or downloading a large file, the Wi-Fi channel will become more congested than the situation that there are no active devices in the network.
Troubleshooting Suggestions:
Normally Network optimization would not cause any network issue and there is no need to scan the network frequently. Sometimes if the Wi-Fi channel is changed too frequently, it may cause an unstable issue on the client devices, some devices may disconnect from the network and reconnect.
So If there were some issues, like slow speed, internet stability, some devices can no longer connect to the Deco network after the optimization proceeds, don't hesitate to contact our Technical Support via email, or leave your comments on this thread. In either case, be sure to provide the following information:
1. The model of the Deco device
2. The number of the Deco nodes
3. The number of connected client devices
4. Detailed issue description
