Xbox New Wireless adapter

Hello gamer,

If you have black adapter with two antennae (wireless N adapter) flashing green light this means the adapter is trying continuously to connect to a wireless network.

In case of flashing red light the adapter might be damaged and you should order a new adapter from the Xbox Online Service Center

Adapter Hardware Checks

To actively fix adapter-recognition problems, check the adapter power light. If the Xbox 360 does not recognize that a wireless adapter even exists, make sure that the power light on the wireless adapter is lit up. If not, taking a close look at the connections
should do the trick. Disconnect and then reconnect the adapter cable, and make sure the USB connection is solid before continuing.

Restoring the Xbox 360 wireless network adapter factory defaults is another direct solution for the adapter hardware. Sometimes, new network settings will not be saved by the wireless adapter. If this happens, a restoration to factory default of the network
adapter hardware is necessary. First navigate to the "System" section in the Xbox 360 Dashboard, then click on the option "Restore Default Settings." After you do so, the light on the wireless adapter will fluctuate between red and green, and then stay on
red once the process is complete. Then fill in the new network settings and password and save them to finish the process.

And, if you can buy or borrow a wireless adapter, try connecting by WiFi if your router has WiFi. New Xbox branded wireless-N adapters go for $60

I contacted the technical support.

The problem will not get fixed. They will release a new wireless adapter next year, which will probably solve the problem. https://www.xbox.com/en-US/xbox-one/accessories/adapters/wireless-adapter-windows

It's the Microsoft adapter:

Observe how the copy says:

With the new and improved Xbox Wireless Adapter for Windows 10, you can play your favorite PC games using any Xbox Wireless Controller.

Note that it says any XBox Wireless controller. If it only works for XBox One controllers, that is, at the very least, misleading.

It appears that I will have to avail myself of the "hassle-free returns" policy.
