What to do when M2M WiFi router network slows down suddenly?

Sometimes the speed of M2M industrial wireless router's internet slows down suddenly while the wired speed is all normal and ruled out. Since there is nothing wrong with line or hardware, then you should be considered whether the channels conflict. Then E-Lins will teach you how to deal with it.

1. HTTP://192.168.1.1/firstly enter into the Tp-link modify Settings page, access with the WiFi password.

2. Click on wireless Settings-basic settings, and then you will see your wifi name and the channel you are using is whether automatic or optional. There are a total of 1-13 channels to choose from, but which channel should be chosen to make WiFi work best?

3.Click on the WDS option to find a scan option below to see which channel your nearby WiFi are using. The best WiFi channels are 1, 6 and 11. These three channels do not interfere with each other and all have strong penetration. If most of your neighbors are using 1, choose 6 or 11 to avoid using one channel at a time.

4. Search the nearby WiFi signal, and select the nearest WiFi, write down its name (public WiFi accounts of Mobile or Unicom are not considered). For example, the closest to me is Liuxuhao and 123, they are respectively using 6 and 11. So I should change my channel to 1, then the download speed will go back to the 1M.
