Hi all,
I just found I can't use the iwconfig tap0 rate 20M to setup the
bandwidth of the tap0. The error message is :
Error for wireless request "Set Bit Rate" (8B20) :
SET failed on device tap0 ; Operation not supported.
But in their video , it can be set in this way. May I know how to solve it ?
The WiFi transceiver is attached to the tun/tap interface, which is a
virtual Ethernet device. This device doesn't support WiFi-specific
configuration through iwconfig.
If you wanted this level of integration, you would have to write a
kernel module that attaches the transceiver to a virtual WiFi card.
Some group already did that, but they didn't release the source code.
Best,
Bastian
