Playstation 3 lost wireless contact to controllers/BD remote after 3.30 update
2010-04-26

Just updated the 120Gb slim PS3 to the latest 3.30 update.

After the update neither of the sixaxis controllers or the BD remote could get any kind of response wirelessly. The controllers worked fine over USB.

No reset seemed to help.

However - the following worked fine.

Turn off PS3
Unplug
Wait 10 secs
Replug and boot
Press PS button on controller over USB to sync
Remove controller and press PS button to get a wireless connection
Repeat with second controller
Use system menu to re-attach BD remote as if it were a new remote.

Now all three are working again.
