It's been two days now and my Xbox isn't letting me connect back to my wifi

i use WiFi i can connect to the network and internet but wont connect to xbox live? been doing this for 2 days and now it wont let me download the new update?....

Its now been 3 days since its been acting like this, I tried restarting my xbox numerous times and it still won't let me connect to a wireless network, I need help trying to figure out how can I connect back to my wifi, If I don't be able to get
this fixed soon I am going to playstation.

Try to unplug your router from the wall then count for 15 seconds then plug it back in that might work

I just purchased a used Xbox 360, everything in my home connect to wifi perfectly. I get the same code, I have reset everything and deleted my cache and deleted my account , but I can't connect so it didn't let me download my profile back. But it still isn't
connecting because of the code

Ok, so it finally let me download my profile again. Hadn't done anything except move my profile to a usb, then back on. Even then it took a day or two. But I'm still having connection issues. It let me play last night after I restarted my router, but then
when I woke up in the morning it wouldn't let me anymore. I tested the xbox live connection and its saying my connection isn't connecting to the internet (Goes from Xbox to the connection, then goes to the internet but can't connect.) Now I doubt there is
something wrong with the router because my laptop, kindle, ipod touch, and even my cousins PS3 can connect to it very easily and have very good speed. I just don't understand why my Xbox is such a piece of crap the past few months. It used to work perfectly
fine.

I'm having the same problem. Lost connection to destiny and now I can't connect back on wifi. Works great on hard wire. Every thing else in my house connects to wifi. And I just got my Xbox one. Not starting off good. I have two ps4s and never had this kind
of trouble.
