Before I start, I have the Wi-Fi Sleep Policy set to Never. Here are the steps I followed for my test. 1. Turned on Wi-Fi to DInc and connected to home router. 2. Found out that the IP address assigned to my DInc was, 192. 168.1.4 3. With DInc screen still on, I went on my computer and pinged the DInc's IP. It came back successful, no packets lost. 3a. With Dinc screen off (Wi-Fi still connected), I went to the computer and pinged the DInc's IP. It came back as "Request Timed Out." 3b. With DInc screen back on (Wi-Fi still connected, and simply on lockscreen), went to the computer and pinged DInc's IP. Successful, no packets lost. Just for giggles, I set the Wi-Fi Sleep Policy to Never When Plugged In. Plugged charger into phone. Repeated all the steps above, and each time it came back successful, whether the screen was on or off. That policy seemed to work. Set Sleep Policy back to Never, and same result...successful when screen was on, but timed out when screen was off. This is driving me crazy! It can't be the router, since data comes in as soon as the phone is awake. When connected to 3G, data will come in whether the phone is awake or asleep. And, I don't have any Task Killers installed. If you can't help, please suggest I try something...anything...please!
