Note that the Realtek devices don't allow you to set gains for RX, only
for TX power.
For the 8723bu it works for me if I remove the device, reload the
driver, restart NetworkMangler, then insert the device. There is
something in the device reset code that doesn't work right at the
moment, but I haven't figured it out yet.
The 8188ru v1 issue is likely different from the 8723bu issue though.
I also won't guarantee you can trust the signal levels reported by
iwlist scan .... it's possible I haven't implemented all of that yet,
but I could be wrong there.
In either case, support for some usage is better than no usage, until we
figure out the remaining problems :)
Cheers,
Jes
