Unable To Open Google Play I've encountering a problem. The problem is that i can't access my Google Play on a my Wi-fi. It is not on a particular tablet or phone. Its all the devices me an my family own. That includes 4 phones and 2 tablets. It only says "No Connection" even when the Wi-fi signals are at full strength. I don't know if this is coincidental but recently I've been receiving this notification that says "Sign into Wi-fi Network". Guys please advice immediately because how can i download awesome apps without the awesome store and i'm not planning to let 3rd party apps populate our devices.
"Sign into Wi-fi Network" says it all: No network, no connection. You most likely changed the password/keyphrase at your router, and forgot to adjust your devices. They cannot log in to the network anymore, hence you get that notification. Fixing your WiFi configuration will solve the other problem along.

Edit: Thanks to Dan for pointing out my omission: The phrasing of the notification indeed points to a "captive network", which requires a sign-in via browser first. To automate such a login, you might wish to take a look at WiFi Web Login and comparable apps. Also see Automate web login for Wi-Fi hotspots (captive portal) on Android at our sister-site.
