I've noticed this before but haven't been able to figure out how to delete it. I guess it has to do with the device searching for stored WiFi networks to establish a connection? Still annoying. According to the article, if you connect to hidden networks then you won't be able to get around this, unfortunately that's almost all the networks I connect to. Couldn't it just do a scan of nearby networks and look up the MAC address of the hidden networks, and, on a match, then try to establish a connection?
