OpenWrt is free software, support for it is provided on a voluntary basis by the developers and fellow users. We will try to answer all questions but please understand that it is not our duty to support you. If that seems like a strange concept then you need to read the following essay: How To Ask Questions The Smart Way. Reading it will certainly save you a lot of time and headaches.
If you feel a slightly grumpy tone in the following sections, please take it as a sign that developers and admins are serious about this. Imagine being one of them, hearing the same questions over and over again. However, don't be frightened, but see it as a guide on how to solve your problems quickly, efficiently, and without annoying too many people all around the globe.

We really hate getting support questions on IRC. Why? IRC is a way to chat with the developers and other OpenWrt users, it's not a toll free technical support hotline. We have no tolerance for people who clearly haven't read the manual or require painfully detailed step by step instructions for even the most trivial task.
“But I have a really serious important question that I need answered URGENTLY!”
What part of “it's not a toll free technical support hotline” didn't you understand? The problem with IRC is that it's instant. You really only get a chance to talk to whoever happens to be around, not whoever happens to actually know something about the subject - post to the forums instead. All too often people don't understand this concept and they think that they're just being ignored so they'll repeatedly ask the exact same question over and over, annoying everyone until they finally get a response.
