Last week it emerged that cable broadband ISP Virgin Media UK had begun deploying a new firmware update v220.127.116.113 for their Hub 3.0 (SuperHub v3) wireless router in order to fix the long running latency bug (here) on the Intel Puma 6 chipset. Today we wanted to share a quick update.
As a quick recap. The CPU (processor) inside the modem component of the Hub 3.0 router was taking on too much work while processing network packets, which caused the chipset to run a high-priority maintenance task every few seconds. Owners noticed that this task was occupying the CPU a bit too much and causing momentary latency spikes (increases of 200 milliseconds+), including a little packet loss.
