Network no longer works

After downloading the Xbox One dashboard preview, my xbox has been glitching. Now that I returned to my xbox, it won't connect yo my network and doesn't even see any networks. What can be done to fix this?

Wireless network connection no longer works on 360 Slim

Hi Lephys - I had the exact same problem (kinda still have but a bit different). And actually have the exact same router - DLink655. After trying everything in the "book" (and no - I don't have any MAC filtering on), the only thing that helped was to enter
in "Additional Settings" on the "Network Settings - Configure Network" - the Alternate MAC address I got form my PC (typing cmd command, ipconfig \all and looking at the physical MAC address). Once I did that - it did connect finally to the internet and Xbox
Live.

However: what it's still hapenning is that it randomly disconnects from XBL - even though now at least I can reconnect every time.

Hope this helps

The rest of the message is merely one of the few generic suggestions it gives, in each instance. "Can't connect to your network... would you like to try a different one?" ; "Can't connect to your network... is it possible you have the security key wrong?".
The last one is simply "Cannot connect to your network hardware. Check www.xbox.com/networkhelp for help."

I tried making sure WPS was off, then resetting the 360's network adapter to factory defaults, powercycling it (the 360), then trying to connect again. I also tried turning off network security alltogether. It STILL couldn't connect. I even tried connecting
to a DIFFERENT unsecured network in my complex, just to see if it would do it. Same exact error... "Cannot connect to network."

I don't understand, unless the built-in wireless just went out or something. But, for whatever reason, it can still scan and detect networks just fine. It simply can't establish a connection with them? And it worked ABSOLUTELY FINE until about 3 days ago.
It had to be Tuesday or Wednesday of this past week.

 

Here is a relevant note from the known issues summary, I hope you find it useful

Wireless Networking:

You may encounter a “wireless network hardware on this console is not working” error when connecting to Xbox Live with a wireless connection.

Your Xbox One console may be unable to detect a wireless connection while an external hard drive is plugged in. Workaround: Unplug the external hard drive, hard reset the console, connect to WiFi, then connect the external hard driv

 

You'll want to create a post in the preview forums (forums.xbox.com/.../default.aspx) to ensure that the proper team is aware of your
issue. It is also very important that you read the list of known issues with the preview updates, as F0REM4N has shared.
