Please can you elaborate? It is impossible to answer your question with so few details.
What type of device shows a full signal? What make/model of router do you have & is this a WiFi connection? Where is this device in relation to the router?
What do you mean by:-
WHEN TRYING TO ACCESS CERTAIN AREAS IT SAYS NO INTERNET CONNECTION
Is this the same device moved to a different area of your property?
