AFAICT forgetting a network does just what it says: it forgets all about joining the network. If you think about it, how could it ignore it if it forgot all about it? And indeed in my tests it doesn't: if Ask to Join Networks is on forgetting a WiFi network will cause it to come right back and ask me to join again. I believe the point is to stop it from auto-joining an existing network (since it "forgets" it).
I don't believe there is a way to selectively suppress a WiFi network from asking to join; you have to turn Ask to Join Networks off. And that's exactly what I have done. It's not much of a problem (no problem at all, actually) for me to pick one--and that gives me a chance to see all that are available too . Once I connect to one it will auto-connect in the future (till I "forget" it, which means it won't auto connect any longer, and with Ask to Join off, I won't be bothered with it again).
So to the OP, why wouldn't you want to turn Ask to Join off, considering your lack of other options? It won't stop you from joining--and saving for auto connect--future WiFi networks. Do you use Ask to Join extensively?
Or is there really some way to selectively ignore a WiFi network? (I couldn't make it work using Forget this Network.)
