Right now, there's a lot of finger pointing when you buy and try to configure a Wi-Fi adapter. Most of the time, it works. When it doesn't, who do you complain to or even get tech support from? When Linksys and Orinoco cards I purchased didn't work in a Sony laptop, I sent email to five different companies and received 15 to 20 suggestions. Fortunately, the last of these, which trickled in, had the solution (Wireless Zero Configuration was turned off).
This does beg the question 'which part of Zero Configuration didn't they understand?'
If it can be turned off, it's not Zero configuration, is it.
