I have no idea what is wrong with my 360's internet connection.

So, yesterday, I decided to get on my 360, and play some Terraria. I was playing, then my friend invited me to a Xbox live Party. First red flag was when I talked, my friend said my voice was lagging very badly. I did the usual, unplug it, then plug it back
in, disconnect the mic power etc.. Did not work. Then I realized it must've been him, so I asked him to do the same thing with his microphone. Note the fact that the previous day, week, month my microphone was having no problem, and my friends thought it sounded
clear, until then. So he did that, and it did not work. I invited another person to the party, and he said the same thing the other guy in the party said. I then came to the conclusion that it's my internet connection. So I got off then reset my router. Then
everything broke loose when I turned my Xbox back on. My Xbox profile took 5 minutes to load when I clicked on it, and the dashboard was not displayed correctly. The background was missing, my avatar and achievements were completely blank and when I clicked
on something, it would tell me to try again later, or that some things are not available right now. Flabbergasted, I invited my same friends from earlier to see if my microphone quality has gotten better. He said not at all. We then tried playing Black Ops
II, but then my Xbox ended up getting disconnected. It wouldn't let me get back on after a few tries, saying my Xbox couldn't connect, but I knew that wasn't true, due to the fact that 1. My 360 is connected directly to the router and 2. My other devices Internet
services were working fine. I decided to see if the same thing is happening with my Xbox One. It displayed everything correctly, and I could jump on a game of Battlefield 4 perfectly fine. So, I decided to just try the next day, which is today. I got on the
Xbox One, and it still worked fine, but when I got on the Xbox 360, at first it wouldn't log me in, but then when it did log me in, it would not load my achievements and avatar. Despite this, I still played Terraria, and then after my session I checked my
achievements, and it still would not show up. I'm almost all out of options at this point, and my Xbox 360, and the 360 only, is pretty much unplayable online. Unknown if it's my internet or Microsoft's, I hope you guys can help me with my long and complex
issue.

Not connecting to Internet

I too have exactly the same problem and have worked through all the troubleshooters. Settings say problem lies between my router and my internet. Funny thing is I am sitting in front of my xbox 360 typing this message wirelessly on the same internet using
the same router and connection. Have no idea what is wrong. Becoming fed up now with Microsoft...just paid for a gold account for my son and he has had hardly any opportunity to use "live" in the last few days due to connection issues.
