Bluetooth and/or WiFi Abruptly and Intermittently Goes Offline on Windows 7 Laptops

Recently I had a symptom in which Bluetooth and WiFi stops working temporarily. This is a problem for me because I often use RDP to connect to my laptop and it drops connections. Interestingly in my case, each time this happens the CPU fans go faster for a bit, so I suspected that this has something to do with the power.

As it turns out, both Bluetooth and WiFi network devices can shut itself down by default due to automatic power management controls.

This behavior can be disabled from the Device Manager (just type these words in at the Start menu) and go to each Bluetooth Radio and WiFi device properties. You will find the Power Management tab where you can configure this.

I just did it so I will update this will or will not work in a longer run.
