A few weeks ago it worked but lately whenever I try to log into live with a guest, it tells me that it can't connect to the internet, but I can log into live just on my own or with a friend using their own log in.
How do I log into Call of Duty live as a guest?

I thought you had to be (or with) a XBox live gold member to play on/with a guest. I could be wrong, but normally you can't use a lot of Xbox live services unless you are a gold member. Guests usually take the other Xbox live user's name (for example, john, and john(1)).
What version of Call of Duty are you playing? Some have bugs that have still not been fixed. I ran into this problem once while playing Black Ops and all I had to do was sign my guest in before I started the game :-). It may not be as easy for you but it's worth a shot.
