Keeping WiFi awake on my Android phone

The other day, I described a problem I was having with my Android phone. When the phone went into sleep mode, the WiFi connection would break. Even after setting the Wi-Fi Sleep Policy to Never, the connection would drop when the display shut off. It made listening to a music or radio stream or downloading anything pretty much impossible.  Security settings on my wireless router didn't matter. The only consistent workaround was to keep the phone plugged into a power source (wall connection or USB). When away from home, the WiFi connection seemed to work as intended.

None of the keep-alive apps had any effect, nor did reinstalling the phone's operating system.

I called Verizon tech support. Their conclusion was that there was probably something amiss with the phone. There were other reports in various forums around the 'net that supported this idea. Because my phone is out of warranty, I couldn't get a replacement. I started thinking about a new phone and gave the iPhone serious consideration.

One Android app, WiFi Analyzer, showed that the neighbors have a couple of access points that occasionally reach into our yard. All of the access points were broadcasting on channel 1.

With nothing better to do and nothing to lose, I switched my router to use channel 6.

Joy.

Since making the channel change, my WiFi connection has not dropped when the phone sleeps. Declaring the problem solved to the extent that anything is ever solved.
