Laptop sleep/idle issues

I have a new Dell E5540 laptop with intel i218-lm network adapter which I normally leave connected to the network. Whenever the laptop goes idle for a long time, I cannot access the network (IE cannot connect to any websites including intranet sites, Outlook cannot connect to O365 etc.). Same issue for both wired and wireless. I've updated the nic drivers and make every possible changes to prevent the laptop from hibernating/sleep. To get this machine going again, I have to log off my profile and log on again. Very annoying!! I'm not sure why this action wakes up the network but it does. Any ideas how I can fix this once and for all aside from dumping it in the garbage?

Hi Totallycool24, can you try to tweak the power management option found in your i218-lm network adapter on device manager. uncheck the "allow the computer the turn off this device to save power". hope this help.

Hi Totallycool24, the "power management" is beside the "Resources" tab when you open up the properties of your network adapter.
