Tried resetting the cards - in fact they seem to require it fairly
frequently - which is a pain as I have to type in a 20-digit WPA key
(twice!) each time

Now there's a mug's game. Store the key in a file on the computer, then
paste it in each time. It irritates me that windows treats it as a secret
password with *s as you type, where it its pretty unlikely that it's that
important to hide it.
