Like Krayziepop said. Make sure you wait a while for the registry to change. I did this a couple times not realizing it and got 67 errors again. I now have my phone running WMWiFiRouter and have not had a 67 in a long time. No need to open the data link first or anything just launch WMWiFiRouter connect on my laptop and I am cruising in a half minute. I can use the usb tether too i just open internet connection sharing instead no errors. Except when I called sprint to get my MSL for my newest mogul
