Tip #3 – Forget the SSID & reconnect
When you try to connect to a wifi network with a password, it must be authorized and the router must accept the request of association to actually work. But, if you see a message stating ‘Rejecting’ or say, ‘Obtaining IP address’ for too long or say ‘Authorizing’, then you are in for a treat. What you need to do is to forget the SSID, password and try to reconnect. Go to ‘Settings >> Wifi’, tap on the network/SSID and forget it.
Tip #4 – Toggle the wifi router
If the wifi is connected to your device but not accessible, try to toggle the wifi router. Check if the wifi is working when you are close to the router. If not, reboot the router. You can also reset the WPS which is a small button behind the router. This must allow you to connect to the wifi.
Tip #5 – Toggle the power saving mode
Power saving mode is essential for those who are away who spend most of their time on the phone or simply away from the power source. Thus, power saving mode restricts most of the background apps in order to save battery backup. If you are using an Android smartphone, background apps and services are most consuming utilities on your phone and thus, when you enable the power saving mode, it restricts unwanted and background apps in order to save battery backup. It can also disable the wifi on your phone. If the wifi isn’t working when you start the power saving mode, disable it and check if the internet works or not.
Tip #6 – Toggle the airplane/flight mode
Most of the time, it is just minor bugs that interfere connecting with the wifi. If it is not working, you can toggle the airplane or flight mode for which, the shortcut is available in the notification tray.
Tip #7 – Update firmware
Outdated apps and firmware may introduce bugs interfering with the working of a smartphone. Try to keep all the apps and especially the firmware updated to provide these temporary errors.
