First, let me stress that I've done a ton of research on this, and have even looked at the forums here for a solution. I've seen other people with a similar problem claim that something that was suggested fixed the issue, so here's hoping -

I have an iPaq 4100. I have a D-Link 614+ wireless router that has worked flawlessly in connecting my kids' desktop PC's wirelessly, along with my tablet PC and an Apple iBook I'd once borrowed.

Nothing...NOTHING I've tried, and no solution I've read thus far will get this iPaq to connect to my home wireless network.

The iPaq finds my SSID, shows a very strong signal, goes through the process of trying to connect, but WILL NOT connect.

This is what I've tried so far:
* Removing encryption from my router and trying again. Didn't work.
* Setting a static IP of 192.168.0.110 (within proper range of my home network) along with the correct subnet mask and gateway. Didn't work.
* Running the welcome program as suggested elsewhere in this forum, and trying again. Didn't work.
* Installing vxutil on the iPaq as suggested elsewhere in this forum. It showed my USB connection perfectly, but showed that I'm getting a 169.xxxx IP address on my wireless connection. I couldn't make that program do anything to correct whatever the problem is.

I repeat - the iPaq shows that my network has a very strong signal - it just will not get a valid IP address. In addition, the iPaq is not detected by my router when I log onto it and check the status of wireless devices. I am not a networking expert by any means, but I am not a novice either.

One time - just once - the iPaq received an IP address from a neighbor's weak wireless signal - but I've never even gotten that to happen again, even via that same weak signal.

It's baffling and frustrating. It SHOULD work. It seems to be configured correctly. But it won't work. I'll really appreciate any other ideas beyond the things I've already unsuccessfully tried.

Thanks!
