I tried for a couple of days to get this adapter to talk to my Ipaq h2215. I managed to get filesharing to work, but not the networking, internet or activesync connections.The "manual" is next to worthless, and nearly devoid of usable information.Incidentally, I have some spread spectrum wireless phones that are 2.4 Ghz units. The working range with this adapter was about 2 feet. Whether it was due to the phones, I don't know, but I was very dissappointed in the range.
