I use KWallet to store all my passwords in, so what I did was to setup KWallet so that it had no password, get NM to store passwords in KWallet, and then I never have to delay things by typing in a password.

But it certainly seems to me that once you have a connection set up with NM, doing any editing of it (including typing in passwords) is likely to cause that connection to break. I tried wicd but it doesn't do 3G connections, which is a bit rubbish.

Actually something in your instructions made it work. I deleted all
entries related to Network manager from kwallet, made it to not prompt
for password, deleted my net from NM, clicked my wifi net in NM, got a
prompt to let NM open kwallet, choosed always allow, got a prompt from
NM to enter the key and it connected to my net and all looks fine.

Thanks for the tip, lets hope it survives a reboot.
