good day,

I face a problem on a daily basis: devices connected to the router are temporarily cut off from the Internet as if they enter the sleep mode  and this is annoying every time I leave my device for some time and open it Nothing works for a few seconds until the Internet reaches again.

the device does not disconnect from the Wi-Fi it connected but without the Internet I thought that this problem is only in my device but I asked my family and it turned out that they face the same problem I have 7 deco... I used Huawei router as a main device and I compass with units of Deco... I did not face this problem only when I used  BE65 5G main router .. 

some times when i face this issue i check my PC at the same time it work normally , my pc connected by ethernet not wifi.

this happened only with devices that connected by wifi.

thank you.
