If no data cannot be transfered over WLAN, the WLAN driver should
disconnect the connection. If not, I would consider that as a bug and
it's a bad idea to try workaround this in userspace. In OSI model
terms, this an L2 issue and for the upper layers it should just work.

Could you describe more about the situation when data transmission is
not possible but the connection is still on, please? Try to give
details as much as possible, so that I could reproduce the problem at
our lab.
