Last night my IP changed , my MAC address i don't know how , i must have done something lol... So will it effect my adsense account?
Agreed, this will not affect Adsense. Google will pick up on your new ip and Adsense wont be affected at all. I changed my ip last month with no problems at all.
Why would it? Your IP doesn't mean anything to Google. A typical dial up user has their IP changed every time they log on.
Absolutely right, I am using DSL and whenever I turned on my PC, I always found a new server IP and I think Google has no problem with it.
