First and foremost, make sure that the wifi is turned on and connected on your device, this can sometimes be looked over. Also a simple solution can be to unplug and restart your router, many times this can cause the problem to go away. If that doesn’t work, go to your search box and type Network Adapters, under that select update driver software. Once it is done your problem should be solved, if you are still experiencing issues please check out this link [[Dell Inspiron 11-3162 Troubleshooting]].
