Excellent Ping

i have bad ping in my bedroom?

ok so ive been trying to play call of duty in my bed on my laptop the last couple of nights and the ping is just so bad that i cant even join a game. However, my internet works fine and i have excellent connection with my wifi. I can play CoD in every other room in the house without any problems but it just wont work in my room. And this has only been a problem recently, i have played here before many times but it stopped working this past week.

does anybody know whats up with this and can help me?

Try moving your router around.
