It could be the chip inside your Xbox. I had to get a new wireless chip because of that problem. Try going wired if you haven't already

ITs been owing fine forever, idk why it would stop working now, when you say chip, do you mean the wireless adapter for the wifi?

Have you tried disconnecting from the router (press Y to disconnect) where you chose the type of connection (Wireless or Wired)

I was having the same issue on my RGH (wired connection though) with the same error code yesterday so I disconnected my Ethernet, unshared my connection on my computer (I'm using a VPN so it's wired to my computer) then I reconnected everything, boom it started working

If its a rgh try to turn live block off or no if that doesn't work try a different stealth

Yes I mean the wireless chip. But then again, it could be your internet messing up. I believe when I had this problem, Idk if I could click wireless wifi and it would give me the error code or if I started testing and it happened. It happened awhile ago. Best bet is to call Microsoft support and they'd give you the best of their help and help you find a solution. Best of luck man

Ya I disconnect and did all the steps they wanted and reset to factory and even moved my Xbox so I could try wired and it didn't work. I just disconnected my router for 15 mins hopefully it'll work now

Oh yea is this an rgh/ jtag or a retail console

Not my rgh haven't tried connecting it yet.

So yea if this is a retail and nothing works then might wanna take it to a repair store. It cost me $60 for the chip and the place was over an hour away
