Teredo or no Teredo: that's the question

Grrrrrrrrrr. Suddenly Eva's laptop (the great Dell Studio Laptop: real great machine) hasn't got IPv6 connectivity anymore. And thus news.ipv6.eweka.nl downloads are not working anymore.

Result of ipconfig:

C:\>ipconfig

What's going on? The only thing that has changed, is a reboot of the Linksys access point. So let's check what happens when I connect the laptop via a wire to the Linksys:

Teredo's back!

That's good news. The bad news:

• Teredo didn't work when connected via wireless, for no clear reason
  
• Windows Vista wasn't saying why there was no Teredo connectivity

Does anybody know if there is any logging about Teredo? Maybe I should have used

C:\>netsh interface teredo show state
Teredo Parameters
---------------------------------------------
Type                    : default
Server Name             : teredo.ipv6.microsoft.com.
Client Refresh Interval : 30 seconds
Client Port             : unspecified
