Mistermac56, the all zeros MAC address is not a good sign. The 4800 should show two MAC addresses - one for wireless and one for wired. Are they both all zeros?
The wired Ethernet works fine and has a MAC address. But the WiFi is not. I had this same problem about six months ago and I unplugged the Roku for a couple of hours and that fixed the WiFi issue. I tried that this time, but it didn't work.
Hi Mistermac56

Please reply here with the serial number of the affected Roku device. It can be found in Settings > System > About. I'll be able to further assist you from there.
We look forward to your response.
All the best,
