Realtek RTL8821CE adapter not showing up after sleep mode

[Yas011]

Hi, i've been fighting with this issue for quite a lot now, sometimes its more frequent than usual but it really never goes away, for some reason after i wake up my pc from sleep mode the wifi disappears, i've tried to update the drivers several times but still nothing, it can get better but its just temporary. I know i'm not the only one with this issue and that this adapter it's problematic but if you know any fix it would be very helpful, just let me know, thanks in advance.

Possibly your Wi-Fi device is not waking up properly when the computer wakes up from sleep or hibernation.

The Wi-Fi device may have a Power Management feature as shown below. If you un-check the box "Allow the computer.." then the Wi-Fi device will be enabled during sleep and will not have to be woken up when the computer resumes from sleep. Laptops in modern standby will be missing the following option.

If there is a yellow bang ! then please show the device and it's ven and dev as illustrated below

If you have modern standby then the above options are not available. Please run the sleep report and sleep study  and try what it recommends.

Thank you for your advice, i tried to change the power plan for the adapter from the old control panel but it wasn't helpful, i forgot to check that box you suggested in the properties, i'll see if this fix it and report in the next days, thanks again.

Cheers
