I have an HP Envy laptop with a Realtek embedded wifi/bluetooth adapter built in.

For the past couple of days, every time it resumes from sleep, the adapter has disappeared from device manager and therefore it never connects to my network. If I power it off and on again, the network adapter reappears.

I've checked all the settings I can find - but nothing changes (there's no power management options in the adapter properties).

Has anyone seen this before and maybe have a solution?

cheers

Alan
