So its been happening now more often than before, I thought it was Destiny just jacking up the console but it appears to happen no matter what as I've seen it happen in other games, while streaming HBOGO, you name it.. I have the Day One edition XB1, since the beginning...
For some reason from time to time, 4 times last night!, the XB1 will just lose all network connectivity, typically manifesting itself by saying Not signed in to Xbox Live.
The XB1 sees my wireless network, settings shows connected with good bars, Open NAT, yet cannot pull any data off the Internet (friends wont show, IE cant connect, Store wont pull up content, etc). The rest of my house is working fine as other devices still can get on Internet.
The only way to get the XB1 back online is to pull the power on it and plug it back in.
XB1 Support, I've read several other articles like this, but the resolution seems to be sending it in for replacement, bad memory, or wifi... let me know how to proceed, this is annoying.
