Xbox-series-x wireless network keeps saying that its wired.

The Xbox series X is Hard wired with CAT 6. The TV and receiver are both wireless. I also use Blue-Ray 4K Disks (No network needed) and have the same issue. I have tried both, wireless and wired. I normally get over 800 Mbps.

Wired network as well. When diagnostics ran on X-box one it says open, and in Ghosts it says moderate. I tried switching to wireless and it went to strict then, but I prefer a wired network anyway.

I'm going to go one better here. I have done all of these steps, and I'm having ENDLESS issues with BOTH an XBox Series S and an XBox Series X. Problem started on June 20th on BOTH boxes. Wired and wireless for both boxes. before anyone says that my home network is broken, I have 2 PCs, several MACs, and a SLEW of other devices having no issues at all on the several wired and wireless networks. I run 4 different SSIDs because, reasons, and the issue followed the XBox, not the network. I finally did a full reset on my series S and continued having issues with downloads starting, running for a while, and halting. I could only get it to continue downloading by rebooting the console.

Are you using a wired or wireless internet connection?

Try a wired connection (ethernet cable) to your network hardware and restart the console. It should connect and do the required OS update.

If wireless choose a factory refresh of the console. After the refresh is complete, input the console setup details again.

Setup new Series X S has further details.

Wired connection for the Series X and wireless for the Series S. Doesn't seem to make much difference.
