Does wifi go to sleep?

Hello, I have the following problem, when the printer has been inactive for a long time, I cannot connect to it via Wi-Fi, the Wi-Fi coverage icon appears on the display, however, I cannot access it, I solve it by entering the printer configuration without doing nothing just entered, but this is annoying, would there be a solution, you have to see that the wifi repeater to which it connects has wifi 5 and 2.4 with the same name, thanks

Separate 5ghz and 2.4ghz wifi and give them different names.
many devices have problems with this.

ok thank you very much, that was my suspicion but i wasn’t sure

I’ve noticed this. I mash the printer up/down buttons and it seems to speed up the connection. Who knew??
