Hi this is my first post. I have a Sylvania SYTAB7MX. I have tried several different WIFI LOCK apps Like Wifi Keep Alive,Wifi Lock,Advanced Wifi LOck. It worked once but then it stopped. I had all 3 installed when it worked so i don't know which one worked. I know you can use ADB and change the wifi sleep policy like you would with a kindle fire but I haven't resorted to that hard and complicated method. Thanks anyone that can help. I appreciate your help. This is a great way to help others with this tablet. I rooted mine so if anyone needs help with that and I installed the Market (OLD). This is a great TABLET but it is just lacking some of the settings that most android phones have!!~~~ Thanks~~~
