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
