The Netgear class action states that the defect stems from Netgear's decision to swap out the Broadcom chipset in the cable modem CM700 with the Puma 6 chipset from Intel Corporation. Intel has acknowledged that the problem stems from its Puma 6 chipset, which causes cable modems to suffer from significant jitter and latency on their network connections.
Hundreds of users have complained in online forums, and Netgear itself has acknowledged the issue. However, Netgear has failed to fix the problem for people who purchased the SB6190 modems, the suit states.
Cable modems containing Intel's Puma 6 chipset that may be affected include:
Super Hub 3 (Arris TG2492LG) (commonly, Virgin Media)
Hitron CGN3 / CDA / CGNV series modems:
Hitron CGNM-3552 (commonly, Rogers)
Hitron CGN3 (eg CGN3-ACSMR)
