Cable Modems with Puma 6 Chipset and Latency Issues

Some cable modems are made with a chipset from Intel, called Puma 6. These modems might have latency issues. This means that information you receive over the internet might be delayed (100's of milleseconds). This can be an issue if you are online gaming or watching some ultra-high-def video. If you're a casual internet user, you might not even notice these delays. There have been some attempts to fix this issue with firmware pushed to modems from the cable companies. There are mixed reports about whether this has fixed or lessened the problem.

We understand the desire to buy one of these modems, due to their low cost. You also might notice that the modems have fairly high ratings from buyers, so it might not be an issue for all. But we wanted you to know about the issue before buying a modem. We've listed on the other pages, some potential alternatives to these modems. The entire discussion about this is too big to get into here, but we've included a list of discussions about the issure here, as well as a list of modems with the Intel Puma 6 chipset:
