Teh WRT54G series launched in 2002 featuring a Broadcom BCM47xx 32-bit processor with 16MB RAM and a 4MB flash memory. The device functions as a router with wired 10/100 Mbps ethernet along with wireless 802.11bg. These devices continue to be a workhorse in WiFi everywhere and spawned several open source firmware projects. OpenWrt and dd-wrt both have their roots here. Almost as a trojan horse, they also brought about IoT in that the Broadcom chipset has since become the basis of the Raspberry Pi.
