I am having trouble connecting up my Desire to my Macbook to make use of my USB Modem via WIFI. I have the USB modem connected to laptop and on the Net. Wifi active on Laptop and phone. Set laptop for Internet sharing from Modem to Wifi. All seems good, but my Desire just keeps telling me "obtaining address" I have tried setting it to static, Removing all Key's , different channels, but my desire is just not connecting. Keep getting "Failed". Driving me insane. Does not seem very keen to work on my Windows 7 Side either.
