Wifi adapters don't need to be 'safely removed' as there is no queuing of info to/from them that could be lost if the adapter was yanked out before any such queue was flushed out.
once you tell it to connect to a network and tick the 'auto connect' box, it should just work.
it should keep trying to find your network.
they tend to just stay plugged in.
don't know any situation where I've seen them pulled out - unless you want to kill the connection quickly.
