Today I helped my friend to setup the gr-ieee802-11.
Everything go well until I try to execute the flowgraph of wifi_loopback.grc
All ports in the GRC are connected. But when I run the wifi_loopback.grc, it stops immediately with below message.
>>> Warning: This flow graph may not have flow control: no audio or RF hardware blocks found.
Add a Misc->Throttle block to your flow graph to avoid CPU congestion.

Any clue of what had gone wrong?
The flowgraph just doesn't execute.
Below is my system info.
