If you're disabling the wi-fi, then you'll have to wait until the TCP 
connection timeout occurs. This might be a long, long time, or possibly 
never, if keepalives aren't enabled.

You could try enabling aggressive values for TCP keepalives on the 
underlying TCP connection, but I'm not sure that's advisable.
