I’m having a hard time trying to get two TP-Link routers (I also have an ER605) connected to my Spectrum modem.  I’ve been working for two days with Spectrum tech support trying to get this resolved, and I think that I’ve restarted the modem and routers more than 50 times.  I absolutely cannot obtain a dynamic IP address with either computer.  The only way that I can connect to the internet is to first plug a computer directly into the modem, see what address it obtains, and use that non-static address in place of a real static one in the WAN settings.

The Spectrum techs say that they cannot see either router on their end.  They can detect a computer that I plug into the modem, but with the routers, there’s nothing.  I have a strong suspicion that this non-visibility is behind all the connection problems.  Is there a way that you can ensure that the router will be visible on the ISP end.?

The MAC address will be reported to the ISP modem.

When you boot up the modem, especially when you replace the old router with a new one, you have to make sure the new router is connected to the modem before booting up the modem.

 

Your ISP always has the authority to flush the MAC address stored on their modem. 

This is a known fact to any US providers. They keep the previous device's MAC address to prevent anyone from removing the old device for security reasons.

Ask them to flush it, and make sure you have the new device connected to the proper port for the Internet and connection. 

 

Or clone the MAC address of the previous device.

  @Clive_A Thanks for getting back to me.  A Spectrum tech came over yesterday and got it to dynamic IP working.  It seemed to be mostly a hardware issue, but order of connection probably played a part.  I'm relaying a Copilot answer that may help anyone referencing this thread in the future:
