It never fails: I always seem to come up with some kind of problem no one has ever seen before, nor have any idea how to fix. However, with my desparation (ie: the wife is very pissed @ me right now), I figured I'd put our new Networking forum to the test and see if you guys can figure this one out. Let's start at the beginning... I have one PC running Windows XP Pro SP2 (the one in my sig & System Profile) which is wired into a DSL modem/gateway/router/WAP. I also have two laptops with b/g Broadcom cards preinstalled (with no PCMCIA slots available to use). I previously had the network running smoothly, sharing files on each machine as well as a printer connected to the main PC. For security, I was using 128-bit WEP. After taking several classes dealing with wireless and security, I felt WEP was no longer a wise choice, and wanted to switch to WPA-PSK. At first, I was able to get WPA-PSK configured and working, but my wife's laptop kept getting the "Limited connection or no availability" warning whenever she booted the laptop. Every single time she turned it on, she would have to go in and "repair" the connection for it to work. It seemed as though this may have something to do with DHCP, as the error occurred with the laptop's IP address being outside the pool. I tried to assign a static IP address, and that worked everytime i rebooted. However, the first time it powered down completely and then back up, the error was back. In the process of trying to figure this out, I realized that the machines were no longer connecting to each other, although the laptops could still access the internet just fine. I talked with two of my teachers, who gave me the standard line about updating drivers and firmware. I updated the drivers on the wife's laptop, as well as the HP Wireless Assistant. I also updated the firmware on my DSL modem to the latest one available. Unfortunately, nothing is working. The firmware update may have even caused more issues, because I can't even get back to WEP. Things I have tried: Reset the DSL modem - no change Made sure the computers were in the same network - MSHOME Tried renaming the network to HomeNetwork - no change Pinged the main PC's loopback address - works Pinged the main PC's IP address (192.168.1.35) - works Pinged the laptop's IP address (192.168.1.33) from the main PC - times out (as it should if it is not finding anything in Network Places anyway) Pinged the laptop's loopback address - works Pinged the laptop's IP address - works Pinged the main PC's IP address from the laptop - times out (as it should if it is not finding anything in Network Places anyway) Ran Window's Network Connection Wizard - no change Ran Window's Wireless Network Connection Wizard - no change Probably tried a few other things too, but I can't remember them offhand. I'll add them as I remember them. Anybody have any suggestions?
