In reply to Tom G.. Thanks for those observations, Tom--it's helpful. Especially the Comcast observations, as I have no experience with Comcast.

I should also note that with Comcast (my current ISP) that I did not have to enable MAC Address Cloning on my DD-WRT enabled router to pull an IP. However, about a month ago, after initially wiping and upgrading the router to a newer version of DD-WRT I booted the router up and it could not pull an IP. I had to power the router down, wait about five minutes, and then boot the router up before the router would pull an IP.

When my sister got Charter Internet back in the mid-2000s, we had to clone the MAC address of her PC to the first router she had. Fast forward some years later, circa 2012, I had to reset her router due to both of us forgetting the password to log in. When I set the router back up I did not setup the MAC Address Clone feature, and the router connected and pulled an IP address without issue.

Before my wife and I got married, she had Charter Internet service. When I set up a router for her, I initially had to setup the MAC Address Clone feature on the router to pull an IP. When we began living together some years later we kept Charter as our ISP. During this time I got a new router and upgraded it to DD-WRT. When I set up this new router sometime in 2011, I found that I did not have to configure the MAC Address Clone feature.

It should be noted that we never had Charter’s Spectrum Internet service, only Charter’s standard cable internet service, so maybe Charter dropped MAC Address filtering and has now reinstated it with the new service.
