HP have released firmware update 1.01.03 for the rw6828.
I’ll be interested to see if this fixed the annoying “feature” where the wireless card spontaneously turns itself on - a great way to shorten the battery life.
Update: This update refuses to install via my Vista machine. I’ll try it at home on the WinXP box to see if it is happier. I had a small panic until I read the readme.txt file which said if the upgrade fails, just pull the battery out and restart it - phew!
