I found a howto somewhere here explaining how to set this up but it doesn't work.
I get to the point of having "connected" on both PC and iPAQ, but I still can't get anything done with it - no Internet, no ActiveSync.
I have it all working with BT, but want Wi-Fi for the longer range. (in retrospect I should have bought a class 1 BT dongle instead, would probably have been easier than meddling with Wi-Fi)
