Analyzing the 2021 firmware for the H2640 also brings up the topic of planned obsolescence. By 2021, the H2640 was a maturing product. While it supported standards like 802.11ac Wi-Fi and VDSL2, the industry was rapidly moving toward Wi-Fi 6 and AX standards. The firmware updates of 2021 can be seen as the device reaching its maturity peak—optimized as much as the hardware would allow, but approaching the end of its prime. For users holding onto these devices, the 2021 firmware represented the "final form" of stability before newer models inevitably replaced them in the ISP supply chain.
