Changing the router's SSID works for some people but not all... but it's better than telling users to rewrite the wi-fi stack so it works. Maybe I'm being optimistic, but I'm assuming they're going to be doing that, but are offering a workaround for some people in the meantime.
To put this in perspective, I have some wakeup issues on both my desktop and my laptop. Neither one Apple. I wouldn't know who to call (microsoft? graphics or wi-fi board maker? motherboard maker? bios maker?) and imagine I would wait 30 minutes and have to pay $40 to be told it's someone else's problem. So I just live with it.
That doesn't make apple right, but perhaps apple users have more of an expectation that the product will work, and they can get apple to fix it if it doesn't?
Note -- not an apple fan-boy. I don't own an apple, unless you count a shuffle.
