Android 7.0 Nougat might well be considered the latest and greatest Android iteration at the moment though that certainly does not apply to all aspects of the operating system. In fact, many Nexus 6P or Nexus 5X owners who have recently upgraded to Nougat have complained of Wi-Fi issues, with the signal getting disconnected often times or not being able to recognize the signal in some cases.
Fortunately, it is not all gloom and doom as there are a few ways that can help establish normalcy.
For instance, one way the Wi-Fi issues can be resolved is by keeping it on at all times. That, in fact, happens to be a feature addition in Nougat and be reached by tapping on Setting and then Wi-Fi.
Next, tap on the Gear icon at the top right corner which will launch the Wi-Fi configures screen. There, select the ‘Keep Wi-Fi during sleep’ option. In the pop-up window that follows, select the ‘Always on’ option. This should resolve the issue though you can also reboot the device for better results. The Wi-Fi should now be showing permanently.
Another way to bypass the Wi-Fi issue is to reset the network setting. You go about doing this by launching the Settings section. There, tap on ‘Backup & reset option’ followed by ‘Network settings reset,’ and then ‘Reset settings.’
One thing to note here is that the entire information stored in your handset pertaining to Wi-Fi, Bluetooth, and the cellular connection is permanently deleted. As such, this can be a great way to solve any issues that you might have with your Bluetooth settings as well. Re-enter all network information again and restart the device.
Uneven battery drain has also been reported by some users who have migrated to Nougat as is a couple of other issues as well. Fortunately, Google is working on the issues and updates are being rolled out to improve the Nougat experience.
Worth mentioning, Wi-Fi had also cropped up initially for some who had upgraded to Android 6.0.1 Marshmallow.
