Software fix coming after Puma 6 code bug hits Virgin Media, Comcast, Arris and other boxes
Intel's Puma 6 chipset, used in gigabit broadband modems around the world, suffers from latency jitter so bad it ruins online gaming and other real-time connections.
The semiconductor giant is preparing a firmware update to correct spikes of lag and bouts of packet loss that repeatedly flare up in home internet hubs in America, Canada, the UK and beyond. A software fix will be pushed to internet subscribers by their ISPs, so if you're affected, look out for a firmware update and modem reboot coming your way. Some people have already been given a beta version of the update to test.
"We are aware of an issue with the Puma 6 system-on-chip software that impacts latency and are working to address it," an Intel spokesman told The Register this week.
Modems powered by Intel's Puma 6 chipset that suffer from bursts of game-killing latency include the Arris Surfboard SB6190, the Hitron CGNV4, and the Compal CH7465-LG, and Puma 6-based modems rebadged by ISPs, such as Virgin Media's Superhub 3 and Comcast's top-end Xfinity boxes. There are other brands, such as Linksys and Cisco, that use the system-on-chip that may also be affected.
The surges in lag are experienced by subscribers on various big ISPs, from Comcast, Charter and Cox in the US to Rogers in Canada and Virgin Media in the UK. You don't need a full 1Gbps connection to trigger the latency spikes – just at least a super-fast package and a buggy modem.
