I am set my Xbox l up and everything but when I go to select my phone I get this notice....

I was just having this same problem and I tried everything on the list, BUT When I went back into my network settings I decided I'd try and just play offline. I selected the "Go Offline" option and signed into my xbox live account but couldn't get any
games to run. When i went back into the network settings I selected "Go Online" and everything just fell into place. Seems the internal WIFI receiver needed a reset.

I am not getting an error code at all. it just says connect to xbox live. Everything says my internet is hooked up and good to go!! ! phones and computer work fine but no xbox live

Same exact problem I am having with both my account on my xbox and daughters account on her xbox.

I am not sure about your controller but I seemed to have solved my disconnecting issues. I noticed when I went to (Settings/Network/Advanced Settings/IP address) that all those settings would randomly all go to zero then return. I also noticed that the IP
address listed there was different than what my router had listed for the xbox one. To solve this I manually entered the IP address that my router had and left everything else the same. This has solved my disconnect issue. Good Luck.

I have also had this same sort of problem as well with Mirror's Edge for my Windows Phone. I have unlocked all achievements on my phone and when I look at my achievements on my phone it says they are all unlocked. But when I look on my Xbox 360 console and
go to my achievements and then select the Mirror's Edge game, it only says I have 19/20 achievements unlocked. On Xbox.com it also says I have all 20/20 unlocked. So can't get my console to be in synch with everything else.
