If your device manager shows "Realtek RTL8188CU," you have the 150 Mbps variant. It became the "Swiss Army Knife" for the DIY tech community
In an optimal environment (line-of-sight to a modern 802.11n router, no interference), the RTL8188CU delivers:
However, the true legacy of the RTL8188CU lies in its . It became the "Swiss Army Knife" for the DIY tech community. Because Realtek chips were produced in such massive quantities, they became the default choice for everything from cheap off-brand dongles to the early Raspberry Pi projects. For a generation of hobbyists, this specific chipset was the first introduction to the frustrations and triumphs of Linux driver compatibility . If you could get the RTL8188CU to work on a custom kernel, you felt like a wizard.
