Very annoyed with Xbox 360 and the connection issues.

So I've been playing on my 360 just fine up until a few days ago. I go to play Black Ops 2 and it signs me out of Live whenever I start the game up. After that I tried clearing my cache and deleting and re-downloading my profile only to get a message saying
that downloading my profile was not possible at the moment. Not only that, I couldn't even sign in to Live on my 360 because every time I tried, it gave me a message saying that I was signed out of Live and if I would like to test my connection. I test it
and it says everything is fine but with possible matchmaking problems. So there I was with a corrupted profile and no reason to play my Xbox 360 seeing as I couldn't even access Live on it. The day after that, I get on, re-download my profile and everything
works fine. I played GTA 5 with few problems except maybe it was hard to find a lobby to play in sometimes which seems odd since I'm in the Southeast of U.S. and using a wired connection. Basically I've never had this kind of problem. And now I try to get
on again today and it's acting the same way as the first day. I get on, I notice I'm not signed in to Live, I try signing in, it says I have been signed out and to test my connection again. Then I turned the Xbox 360 off and back on and now my profile isn't
even showing on my list of profiles. It's in my memory as a corrupted profile but I didn't even try downloading it again because it caused that exact thing last time. Help me out please.

this new 2 step verification thing is crap. its so secure ppl have issues connecting to their own system. had to do this for my xbox one. and since you guys couldnt let us carry over our games from 360 to xbox one. now we have to go through this annoying
issue with our 360 as well. -_- its very frustrating and dumb. very very annoyed right now

 

Very annoyed...

I still have these problems with the static IP and DMZ done and when I can't sign in to my profile I can't even play the xbox one. Another thing that needs looking in to is xbox can't do any thing about any game that don't play right you have to phone the
game company's costumer service which see fit to give you the run around and tell you it don't happen in the game where do old school gamers go now it all about the money and nothing to do with service anymore ...??????????????????????????it's gone well past
funny xbox get involved, that if you care .

 

Ok so it is currently fixed. I re-downloaded the profile successfully this time and it is connected to Live. There still may be something wrong but I guess time will tell.
