Recently it has come to my attention that users with there vita's on both the wifi version and wifi and 3g version have been experienceing some problems staying connected to the playstation store via the vita and firmware update 1.80 here is the solution.

1. make sure your routers signal strength is set to 40 mhz 20mhz is too weak for the vita to stay connected and will end up connecting then disconnecting the wifi.

2. check channels where you live at if someone is using channel 5 on there wireless use channel 6 and so on and so forth
