No Power Save is a portable freeware app designed to eliminate several steps required to perform default Windows power option changes when experiencing Wi-Fi connectivity issues.
Not that the steps to change your power options are tricky at any stretch, but No Power Save makes it even more straightforward to complete. Instead of you having to navigate to Network Adapter and Power Options settings, you run this tool, and it does it all for you in minimal clicks.
No Power Save deploys quickly and will require you to reboot for any requested changed to take place. It should be noted that by disabling power-saving mode, you may cause a Wake on Lan issue, the author recommends disabling.
