Error: XRE-00021, have reset two cable boxes, no help. internet ok. Some non major channels work. It's the CBS, NBC, Golf, etc that do not work. Very frustrating since COX service technicians not available till next Friday.
00021 is a signal issue. Can you describe how the cable boxes are hooked to coaxial in your house? Also, please post your modem's signal levels from 192.168.100.1 webpage. Last, does it work if you bypass the splitter?
