I think this thread is already too far down the line for this comment to make a difference, but I don't think it's very helpful to say your wifi is working. Of course it works. The question is, does it work well?
How many bars do you get at different distances from your router? How does this compare to the signal strength on your laptop? It's pretty apparent that the wifi on the 8320 isn't as zippy as many people had hoped (see
the speed test BGR just ran). The question is, do these issues vary by device? Are some 8320's picking up a signal better than others, or are they all pretty lag-tastic?
