Droid 2 wifi and roaming problems

[anonomousfiend]

Hey guys, first post here.
lately I've been having a problem using my wifi, It used to be tons faster than 3g but now, it wont even load anything. Nothing on the router has been changed, and nothing on the phone has changed, what's going on?

Also, my phone keeps randomly having an alert pop up, saying im out of the USA, and asks me if I wanna enable roaming data, when im not even close to being out of the usa, any ideas or suggestions?
