Warning 5 dynamic range window violations

The warning message you're seeing is related to the power levels being used by your cable modem and the cable modem termination system (CMTS) in your network. Specifically, the message is indicating that the "commanded power" being used by your modem exceeds the value that corresponds to the top of the DRW (Dynamic Range Window).

The DRW is a range of acceptable signal power levels that is used to ensure that the cable modem and CMTS can communicate effectively with each other. If the commanded power level of the modem exceeds the top of the DRW, it can cause problems with the communication between the modem and the CMTS, and may result in degraded performance or even a loss of connectivity.

In this case, it's possible that the commanded power level of your modem is set too high, and you may need to adjust it to a lower value in order to avoid issues with your network. You can try restarting your router and see if the issue goes away. If the issue persists, you may want to contact your Internet Service Provider (ISP) or router manufacturer for further assistance.

@Cma16 

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1 

Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

This my snr

It looks like some stuff is out of spec but it is hard to decipher because of the poor formatting of the text. Can you fix it ?

I'm having the same problem.
