This is an old thread, but I've seen this problem a lot while playing Iron Banner/Trials of Osiris/Crucible in Destiny on my Xbox One. This guy found and caught some cheaters that seem to cause these symptoms here:

Bungie acknowledged this issue and should be dealing with the cheaters swiftly in this weeks updated published 5/29/15 here:

As some other members mention above, clearing your MAC Address may be a resolution to getting back online, but it's always worked for me to just hard restart my Xbox One by holding the power button until it restarts

Having same problem right now, did you end up fixing it?

This has been happening to me on and off, usually a hard reset works. Not today however, while playing Destiny it randomly disconnected from xbox live(as destiny likes to do) but now when i go to connect it wont accept my wifi password. All my other devices
are connecting fine, even the old 360. No passwords have been changed and the right password has been entered multiple times into the Xbox one to no avail, the XB1 can even see my wifi network but just decides it has to create a problem by being all "nope
even though i've connected to this *** 1000 times, i'm gona screw you over" the proper ports are open, there is nothing wrong with my router. so what Xbox live team, am i suppose to sacrifice the connectivity of all my other devices by resetting everything
in my wifi network. Also your customer service team(phone wise) seems to be completely useless, do you pull these guys out of the slums of Delhi? and tell them just to repeat to people that they need to move their xbox closer to their router? or that i have
to do a hard reset? its embarrassing and offensive to anyone with even basic computer literacy. Alright /end rant this is a serious problem and while im happy to go back to my PC its making me mothball my Xbox and seriously question my purchase.

The same exact issue MetalHeadChiyo experienced is happening to me. I tried 2.4GHz and 5GHz bands, happened on both eventually. Nothing else on my network is dropping a connection. Not downloading or streaming anything anywhere when it happens. Destiny will
just boot me with one of their 5 million networking error codes, I'll lose connectivity, and won't allow me to connect back to my wifi b/c it tells me the password is invalid. A hard reboot works every time (don't just power console off, pull the plug) but
this is complete BS.
