I set up one node to be an access point and lan to lan the AP to connect to the mesh.  That works fine.  I can scan the wireless devices on my laptop and I do see the AP and can connect to it and then on to the mesh just fine.  problem is the AP is open where anyone with a wireless laptop, cell phone etc can connect to it.  I did set up the password in the AP's setup screen.  Is there some other way of securing the AP?  I don't want to leave this open to just anyone.

Thanks
