Very vega about the update, cause I can't find one?!?
Wher is the update for Timecapsul? you make it so hard to find it's riducudlous...
You do not download it.. you simply set the TC to update and it does it.
If you are on Lion download and use 5.6 utility instead of using the toy version 6.0
Go to the top menu when you open the utility and look at Base Station.. Upload Firmware.
BTW. firmware after 7.5.2 is well worth avoiding.
