Communication falls off regularly, without a schedule. Maybe every 10 minutes, can keep it all day, but always after waking up from sleep mode. How to trace the cause, cure?

Run in terminal
dmesg -w
and leave it hanging like this.
When the Wi-Fi cuts again - look at what it says.
By the fact that he writes, you can then google.
