Ps3 controller or Internet connection?

[758]

I went to play black ops 2, and first I couldn't sprint. Then I go to throw a grenade and it goes nowhere and blows me up. I thought it might be my controller so I tossed in Skyrim. I could still crouch and throw my voice, so I don't think it's my controller. I tried black ops 2 again and had the same exact problem. My friend said I should try re-inserting my Internet info in my 'Settings' option. I don't see how that could make a difference

Does anyone know what the problem might be?? Is it my controller??

Or is it my Internet connection??

Internet connection. Try doing what your friend says and if that does not work, you may need to change the channels on your wireless router. If you have many internet connected devices at your house (>3), then they may interfere with your ps3's signal. Also, if microwaves are on between you router and your ps3, you are really in trouble (they mess up wireless signals).

I am not an expert in wireless routers, so you may need to post a question of you to change your channel in a different section of yahoo answers.
