I have an app on my tablet similar to cromecast. Only thing is in my room the wifi is very weak and video is always stops to buffer every 5 minutes.
Is there a way I can increase the range of the wifi?
Router is on the first floor in the front of the house and I am on the 2nd floor in the back of the house.
Router can't be moved.
Do I need to buy a range expander or another router?
