Comcast: Xbox 360 cannot connect to any of my apps says not signed in

try removing the account from the console, clear the console cache, and then re-adding the account

I am having issues signing into the app itself due to Comcast/Xfinity are not. Listed as providers so I cannot. Watch my team play and that's frustrating to say the least

those with comcast and xbox one, most comcast wireless modems and the one dont get along, you have to hardwire, i still cannot wirelessly connect after months but hardwire fine everytime. I have both the 360 and the one they both connect fine, but whatever
live issue is going on its keeping my gold account ***, ihave yearly that was paid and receipt in january, should not be saying i dont have gold, lets me connect, all net connections are A ok and fine, but it will not recognise my gold account and even trying
to repurchase its saying cant have two, this is crazy frustrating, if gold subscribtions is messing up would explain all app issues as they all check for it first.

Same here! I cant even sign into my account, whats going on? Trying to sign in and says cant connect to xbox live. I also have comcast.

I have tried clearing cache, setting up a static iP address, doing a full reset on my console (where you clear it out but keep games and apps) and nothing has resolved this issue.

I still cannot connect to Xbox live when playing an Xbox 360 game and since I deleted my account in an effort to re-download it, it is gone and I can't even sign into my Xbox 360 online account. And CANNOT PLAY ANY OF MY GAMES THAT REQUIRE ME TO SIGN IN.
