Dear Geeks - a question - router/WiFi

My WiFi signal is weak now. It used to reach from the 1st floor to the 2nd floor. Now, I must stand at least 10 feet from the router or the signal disappears. Is this the way routers wear out?
Direct connections like the desktop and magicJack work fine.

As I am writing, my tablet sits 7 feet from the router, and the WiFi signal is bouncing from strong to gone.

Is the router dying?
It is an Etapa TP-Link.
If I need a new one, what is the BEST most powerful, and where can I buy one?
