Freaking power adaptor

Yesterday a friend of mine asked me for help with his wireless access point.  Although the warranty has already expired, I thought perhaps they can take a look.  The problem is, we cannot power it on any more.

Now that I'm about to go to the shop, I thought perhaps I should test the power adapter with my multitester... and holly shit!  That piece of crap is giving 16V when it should be supplying only 12V!  That's a whole 33% more than it should, and it's been operating like that for about a year.  That power adapter came with the wireless AP, and it's clearly labeled as 12V output.  The wireless AP is also labeled as requiring 12V input.  I'm not surprised it's broken.  Fuck.  Stay away from LevelOne wireless access point model number WBR-3407A.  How annoying.
