This issue has been pleging me for months but I did not have time to really try to fix it. Today I spent the hole day on the issue. I called HP several times and they where not very helpful.
After reading many many many solutions, here is what worked for me:
I did create a new power plan with . Power management
and made sure thge wireless seting were set to maximum
I did uncheck the box where it says "Allow the computer to turn off this device to save power".
This seams to have fixed the issue for me.
Hope this helps
