Question about DOCSIS 3.0 standard compliant modem

I recently got an email from COX Cable announcing that they'd graciously increased our Internet speeds. After noticing no difference in speed weeks after the notice, I emailed them to ask why nothing seemed different. They said that my modem would not support the new DOCSIS 3.0 standard and therefore I would have to upgrade to a new modem. I found a CISCO DCP3010 modem that met ther requirements and hooked it up today. I also have a CISCO E2000 Router (previously purchased) attached it it. After swapping out the old modem for the new one, and then starting my computer, I called COX with the new MAC address for my new modem in order to re-establish my connection. The COX tech did what he had to do from his end while I watched my modem to confirm that it was starting up and that I had a connection. At one point, he told me that I should now have a connection, but my taskbar icon said I wasn't connected and the DS, US and Online lights were amber instead of green, as I expected them to be. He said to wait a minute and tried something else. The lights all turned off, then one by one began to blink, then turn solid green. "Cool", I thought. I looked down at the taskbar and saw that I had a connection, opened the Nertwork and Sharing center and sure enough, I was online. Then I noticed that the DS, US and Online lights were amber again. I asked the tech why ther weren't green and he had no idea. He suggested that perhaps it was because I was connected to a router. The main thing, he said, was that I had my connection back, then asked if there was anything else I needed.

So, my question is, why are these three lights not green? Would anyone agree with the COX Tech that the fact that they're amber is not an issue to be concerned about? Does this have anything to do with bonded channels? I'm bringing the question here rather than going back to COX to inquire further because the Tech there did not really have an answer to the question. If the 3 lights ought to be green, then obviously, I'd like to know that and also know if there's something I can do to remedy the issue. I'm not not a hard-core networking person, but I am capable of comprehending and following clear directions if there is a fix that I could perform. Any input would be helpful.

BTW, hope you all have a Happy Thanksgiving!! :-)

AFAIK, the lights are supposed to be green. Since it's a Cisco product, I would contact them.

How do you know when a politician is lying? His mouth is moving.

According to this the modem can't be amber but only green lights.

On my Motorola docsis 3 modem the link like goes amber if at 100mb but blue if 1000mb

There are other discussions on the web about bonded vs unbonded connections

What you needed to have done previously was a speedtest.net test before and after the modem replacement to see if you had improvement or not.

After I rebooted my computer, all of the lights that had been amber, turned green, as they are supposed to. When I initially called COX, it was to give them the serial number and the MAC address of the new CISCO DCP3010. Since I was speaking with a person who was a Tech, I let him do whatever he needed to do in order to re-establish my Internet connection. I asked him why the DS, US and Online lights were amber instead of green, and he didn't seem to have any answer. I thought that was odd, since, even with my level of experience, I knew the lights ought to be green. However, since this is a DOCSIS 3.0 modem, my immediate reaction was to not panic. I figured that perhaps this new modem was somehow different than my earlier 2.0 modem, and maybe the amber lights were normal for a 3.0.

As soon as I closed my call with COX, and while still online, I sought out the CISCO install PDF online and checked it out again. It's not the most informative information source, but that's all their is. It was clear that the lights should be greem if everything is working properly. It was at that point that I came here hoping to get someone else's input.

When I was done, I shut my system down. The next time I booted up the computer, I checked the amber lights, and guess what? They were green. That's all fine and good, but then I noticed that the "Link" light, which had been green, is now amber and it's blinking all the time. I didn't read anything about this in the CISCO info PDF. I found one related comment from a COX Support Forum Moderator who says, "The amber link light indicates a non-Gigabit Ethernet connection. If it only goes amber with the router connected it sounds like the router and modem aren't negotiating a gigabit link correctly. Maybe that can be set in the router settings or could indicate that the WAN port on the router may be experiencing problems." As I've said before, I am not a "network" person, and while this answere may be "the" answer, I am not certain where in the Router settings I'd be looking. By "router settings, I assume that he meant the Router Config, which I am somewhat familiar with. Anyhow, I'll probably try calling COX again, and hopefully will get a more knowledgeable Tech to assist me the next time. This isn't a critical emergency for me. I'm online and everything on my network is working just fine. It's just that nothing seems any faster than before, and I don't understand the blinking amber "Link " light. The issues with the lights struck me as something worth investigating despite the fact that I'm up and runnig okay otherwise.

Had a similar situation. Bought a new cable and all was good. That assumes the routers wan port supports gigabit.

I hadn't given much thought to new cables, but I will look into it. Is there a different or special type of cable that I should be using? I was previously using a CISCO CM100 modem connected to the E2000 router. Except for one new cable that came with the new CISCO DCP3010 modem, I continued to use the other, existing cables.

Here is a link to the specs of my CISCO E2000 router. It seems as though it supports gigabit. Let me know if you agree. Thanks!
