Bricking a wireless device means: You've screwed it up so badly that it doesn't work anymore, i.e. you've turned it into a brick. This can happen due to incorrect firmware upgrading, simple pot luck, or Hacking (modifying the firmware) e.g. LinkSysHacking.

I like the quote from RoDent.. "I will gladly brick it for you" .. I just thought that that saying merits mentioning --

RoDent:: If you haven't bricked at least one device, you haven't learnt anything...
