I just spent the last 2 hours trying to get 802.11g running smoothly home (upgrading from 802.11b for a variety of reasons) between a Netgear FWAG114 (not for sale anymore?!?), my work’s HP TC1100, and my custom PC’s Linksys DWL-G510.

I was trying to get all three devices to do WPA-PSK with TKIP, but I could only get one of the client devices to connect at any one point.  Having them both up and running just wouldn’t seem to work. 

While not conclusive, this forum post seems to lead me to believe that there might be some interoperability issues with WPA.

So for now, I had to go back to Shared WEP with no broadcast SSID. Definitely not ideal but better than wide open.
