Invalid WI-FI Networks showing in "WI-FI Networks" list In my WI-FI list, I see 5 password protected WI-FI networks that appear to be in range. The problem is, I know these networks are not in range. It appears as if I was in range at some point and when I got out of range they did not go away. They show as available at home, at work(20 minutes from home), at the cottage(2 hours north of here) and anywhere else that I go.

I have never connected to these and I do not know the password to any of them. If I press and hold on them, the only option I have is "Connect to a network" so I cannot "Forget" them as I was never connected in the first place.

What could have caused these to start appearing in the list? Is there a way to get these out of my available "WI-FI Networks" list?
While all networks you've connected to in the past are stored in a file called /data/misc/wifi/wpa_supplicant.conf, networks "just seen" around (but never connected to) are IMHO not stored to any file, but just "cached" in memory. So a simple trick to get rid of them is to enter airplane-mode for a couple of seconds (or a minute if seconds are not enough). With WiFi being disabled, the system should see no reason to "stick" to that "cached" information, and thus "forget" the unknown networks. As soon as you return from airplane mode, it would need to "rebuild" its cache again – but those "stickies" should be gone for good (until next time, maybe, but then simply repeat the action).
