Changing nwid on a wifi network means it is a new network. By definition
the WPA crypto keys use the nwid as part of the crypto hash. And it is
super unlikely that a differently named network will have the same WEP
key. In that case, you can enter it again.
With this, when you change wifi networks, you don't have to remember what
else you have to remove.
OK?
