Severe Intel Puma 6 chip Latency Issue -- 3.5 Rating
Reviewed in the United States on March 8, 2019
My old DOCSIS 2.0 (1 x1) Motorola SB5101U had a 17 megabits/s download speed and 1.75 megabits/s upload speed on my current/new HS internet account of 100megabits/s D/L and 5megabits/s U/L with (24 x 4) channels allotted.So I thought to upgrade using the Linksys CM3024 DOCSIS 3.0 (24 x 8). The first number indicates the download channels (24) and the second number (8) the upload channels. The higher the number the better.You can see by looking at the pictures that the Linksys CM3024 is vastly underperforming on the download side (promoted to have transfer rates up to 960 Mbps)--only seeing 13.5Mbps which is SLOWER than my old DOCSIS 2.0 modem with slightly over 17 Mbps and pretty much performing as expected--maybe slightly higher on the upload side 5.79Mbps with my current ISP account.After doing some online troubleshooting/search, discovered that the Intel Puma 6 chip, which the CM3024 uses, has some severe "latency" issues according to some claims. This has resulted in many Cable Modems, including the Linksys CM3024, being put on "Do Not Use" lists. As far as I can tell there is currently no fix for this problem and you will not see the claimed speeds this modem promotes. (see UPDATE: below)I am returning the Linksys modem and have ordered (after further research) the NETGEAR CM500 (16 x 4) which does NOT have the Intel Puma 6 chip. I will be happy to report on the performance of the new modem when i provision it on my ISP.UPDATE:I Received the NETGEAR CM500 (which does not have the Intel Puma 6 chip). I followed the directions completely to provision it to my ISP, which involved connecting your modem DIRECTLY to a computer not through a Router. I did the speed test on DSLREPORTS; the results are posted as the third picture (106Mbps D/L, 5Mbps U/L) -- SWEEET!I reconnected everything, including my VPN router( key point here), and did the speed test again. Results are picture 4 (21Mbps D/L, 4,78Mbps U/L)-- UH OH! I did some more research and it appears that some have claimed that a VPN tunnel drops the throughput, which is what I'm seeing.CONCLUSION:In light of the issue with using a VPN router, A complete/accurate test of the 3 Modems, the original DOCSIS 2.0, and the 2 DOCSIS 3.0 modems should have been conducted via a direct connection between a computer and the modem and ISP.I am glad the speed issue arose, as I wouldn't have known about the Intel Puma 6 Chip Latency issue with the Linksys CM3024, because I wouldn't have done the research. I already returned the Linksys and cannot reprovision it to speed test it correctly. I imagine that the speed test would have been good. But I think I would have returned it anyway for a Non Intel Puma 6 Modem.I am raising my rating to a 3.5 on this Linksys CM 3024 Modem.
