Problem with CISCO DPC3010 DOCSIS 3.0 Modem
Several months ago, I received a COX email telling me that I needed to upgrade to a DOCSIS 3.0 Modem in order to take advantage of the higher speeds that were now available. I presently have Cox High Speed Internet Preferred. After checking the COX site for a suitable modem replacement, I bought a CISCO DPC3010 DOCSIS 3.0 modem. I also have a Linksys E2000 Wireless-N Router (802.11a/b/g/n 300Mbps, 10/100/1000 Mbps Gigabit Port x4, 2.4/5GHz Selectable Dual Band). Once I installed the new modem, I called COX to register the MAC address. While the technician was getting me set up, I noticed that, even though I had a connection, the "Link" light was flashing "amber", when it ought to be solid green. I've been to several discussion groups online to investigate this and the best answer I've found is that I am not running at the DOCSIS 3.0 speeds. In fact, I don't think my speeds are any different than they were when I was using the older modem. Whether I am online or not, the "Link" light continues to flash an "amber" light. I read a reply on one discussion group from a COX Tech named Chris who suggested to a customer who was having the same issues, that he needed to have COX remove his older service code settings and replace them with DOCSIS 3.0 code. Frankly, I don't know whether this was done when I called COX or not. The Tech I was speaking to didn't seem to know anything about the DPC3010 modem or why the Link light was flashing, and didn't give me any logical explanation for the problem. He wasn't able to fix the problem. As far as he was concerned, as long as I had a connection, everything was good. Considering that I purchased this new modem as a result of COX telling me that I needed to upgrade my modem, I would like to enjoy the benefit of the higher speeds that I was supposed to be getting. When I check the Local Area Connection Status for my Internet connection, it says my speed is 1Gbps. That is exactly what it was with my old CISCO 2.0 modem. I ran a COX speed test tonight that said 32.66Mbps download and 21.88 upload at 29ms. I don't know if this is good or bad. Of course, when I ran the test a few times, the up/down speeds were lower. Can you check my account and conform that DOCSIS 3.0 code was activated for my service? What suggestions can you offer to explain the flashing amber Link light, and what can be done to fix this so that it's running properly? I'm beginning to wonder why I needed to upgrade my modem if it didn't improve the service. Thanks for any assistance you can provide. -Russell F.
