What are the odds of getting a working WIFI if I return the Acer R7-571 unit?

Since I read a post from Acer (shown below) that only a small percentage of units are affected. What are the odds I will get a working unit if I return mine?

I will give this 2 days to try to resolve. I have spent 4 to 5 hours on different tests and research. I know Acer will say contact them and have it shipped back, but in doing that I will lose the option of returning it to Best Buy for a refund. There should be a "lemon law" with computers and maybe then companies would be more motivated to fix obvious issues.

In looking at other threads on this forums they have a few replies, the one on the Acer WIFI issues, has hundreds. Their customer sevice reminds me of a quote from Gordon Gecko in Wall Street :

"If they owned a funeral home, no one would be dying!"

Acer's post from a few weeks ago :

We’ve been monitoring the complaints received regarding the wireless capabilities in the R7-571 for some time now and recognize that while it is affecting a small percentage of units, we want to address this immediately.
