UPC Wi-Free requires to enter a username and password, but when I try to connect, it doesn't ask me for it, but rather tries to connect right away - which of course fails.
I have read Change the password Windows 7 has stored for a wireless network , but don't have "Manage Wireless Networks" in the "Network and sharing Center". Also, the network I need to enter the credentials for ('UPC Wi-Free') isn't displayed in the list of registered networks, also not when entering "netsh wlan show profiles", so it doesn't (seem to) be saved on the computer, which also means I can't delete it from the list to get queried again.
Any idea what else I could do? Somehow it feels the network might still be saved 'somehow' (I set it up many months ago, but changed passwords since then), but in a hidden way, so login fails. Or whatever. x-)
