nexus 7 can't connect from home wifi?

First, you’ll want to reboot your phone or tablet. You’ll also want to try rebooting your router if you haven’t done that in awhile. We recommend unplugging the router for a good 30 seconds and then plugging it back in. You can do the same for your modem as well. If those simple fixes do not work, it’s worth heading into your device’s settings.

There, you’ll want to try forgetting your Wi-Fi network. Simply press down on the desired network and a white menu will pop up. At the top, you’ll see an option that says Forget network. Select that and then reenter your password to connect again. If that doesn’t work, try changing the frequency. To do that, click the vertical dots in the top right corner to bring up the Advanced menu. Go to Wi-Fi frequency band and play around with the settings. It should be set to Automatic by default.

If none of that works, we recommend updating your applications. If apps aren’t causing the problem then it’s probably worth trying another router to see if it’s your other hardware causing the issue. Older routers misbehave more than others. If none of that works, we recommend performing a factory reset.
