Very strange wireless internet problem?

Question

i am living in france and am expirencing sum trouble with my wireless internet

it IS connecting to the modem

it is NOT connecting to the internet

my EITHERNET port does not work either

The PC in my BED ROOM will connect

my grandads LAPTOP will connect

Answer 1

If it's connecting to the modem, but the ethernet connection isn't working, what connection on the computer is connecting to the modem.  (And the make and model of the modem might help us to help you.)

Answer 2

Maybe it is a local internet connection? If my router turns into local internet mode, i cannot connect even though a connection between the laptop and the router has been established. Google what i've said to find out more.  

Answer 3

Your question does not make sense. You are saying it does not connect to the internet, but the bedroom and laptop DO connect to the internet?

Not logically possible, unless you are saying one PC can not connect
