May I ask, how did you get to know that the wireless radio is not working?
Let us print a wireless test report:
1. From the printer control panel, touch Wireless icon.
2. Touch Settings, and then touch Print Reports
3. Touch Wireless Test Report. Check if wireless is working.
On the printer screen, go to Setup > Network Setup > Restore network settings
Go back to Network > Wireless > Wireless setup wizard and select your network.
Make sure the printer and the PC are connected to the same wireless network.
If you have a Dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both the networks.
Hope this helps! Keep me posted.
