Comment 285 for bug 113201

"Auto detect" is nothing magical, it's just a way for the browser to find out where the Automatic proxy configuration URL is located. In your case (if you're using wildblue.net as your DNS suffix), according to <http://help.wildblue.net/kb/article/2751>, I guess it will automatically look for the URL <http://wpad.wildblue.net/wpad.dat> instead of the <http://wpad.wildblue.com/wpad.dat> installed by the Wildblue Optimizer. I can't see from the outside if this is the same or not. If your DNS suffix is wildblue.com, then the 2 settings are exactly the same.

Anyway, there might be a problem with the proxy server(s) itself, or with the DNS request that your browser is using when using the wpad-file. Or with the pipelining that the Optimizer has installed (in which case it might also dependent on the exact website that you're visiting).

I'm not sure if you really need that wpad-file, it might be possible that you can surf faster without it. Or maybe you can try switching off the pipe-lining, especially the non-proxy pipelining, see <http://kb.mozillazine.org/Network.http.pipelining>.
