Intel Puma 6 and Puma 7 Cable Modem-Router Investigation

Migliaccio & Rathod LLP is investigating cable modem–router combinations using Intel Puma 6 and Puma 7 chipsets for chronic latency spikes, jitter, and degraded performance tied to a well-documented hardware-level defect.

Reported Issues

Consumers and network engineers have documented:

  • Severe latency spikes under load due to chipset-level architecture flaws
  • High jitter affecting gaming, VoIP, and streaming
  • ISP-approved gateways—such as Arris SB6190 and some Netgear AC1750 modem-routers—exhibiting persistent connectivity issues
  • Firmware updates failing to fully resolve the underlying defect
  • Existing class actions already filed for specific Puma-6 devices (e.g., SB6190)

Experts characterize the issue as baked into the silicon, not fixable via software.

Why Consumers Should Be Concerned

Consumers may have spent premium prices for “high-speed” or “gaming”-grade modem-router combos that never could meet their advertised performance due to hardware design flaws.

This may violate:

  • State UDAP statutes for selling devices with known defects
  • Implied warranties where core functions (low latency, stable throughput) fail
  • False-advertising laws related to speed and performance
  • Magnuson-Moss, if warranties failed to disclose these limitations

Existing litigation strengthens the evidentiary basis for future model-specific actions.

Signs You May Be Affected

  • Own an Arris SB6190, or a modem-router combo using Intel Puma-6 and Puma-7
  • Experience latency spikes during gaming or video calls
  • Have jitter issues even when signal levels are normal
  • Returned or replaced multiple units due to the same performance problem
  • Were unaware your device used the Puma chipset
