    My password simply will not change! After doing the above, typing in a new password, and hitting “ok”, the only thing it does is to knock my wifi connection out. I then have to go in and “forget” the connection, then go to reconnect where it prompts me for the password….and it will only take the “old” password. Checking the setting in the security tab, it is right back to the old one. It simply will not let me change the password. I suspect that I’ll have to remove the connection entirely and create a new one. Thanks Microsoft! *sigh* (And now….it’s Linux time! I’m too fed up with Microsoft crap)
