RPi3 WiFi Power Management Setting

I’m running the 5/3/16 RPi2 nightly build of Lakka on a new Raspberry Pi 3. Network performance using the onboard wifi is terrible - frequently seeing pings at 3000ms and transfers at single-digit KB/s. Other devices on my network are not suffering this type of performance. Looking around the internet, these symptoms are common when the onboard wifi is run in low power mode. Recent development on OpenElec have incorporated the fix, but I wasn’t sure if it has been pulled into Lakka yet. Below is a link that talks about it further.

I may be barking up the wrong tree, but wanted to check if this is a possible reason for the issues I’m seeing. Unfortunately, I’m not sure how to check to power setting on my own.

Thanks.
