    Wireless issues

    We just made changes to the wireless security at work on Friday. Since then, we have 5 desktops (non-domain) that are unable to maintain a wireless connection.

    What we went from:

    WPA-Personal
    TKIP

    What we went to:

    WPA2-Personal
    AES

    I have replaced the crappy USB wireless adapters with PCIe adapters, but the issue still remains. I have also done the usual ipconfig /flushdns, /release, /renew along with netsh winsock reset and ip reset.

    I also attempted to change the wireless channel in hopes that it would clear up possible interference that might be causing this. Unfortunately, a clear channel in my office does not make for a clear channel by these desktops, so that was reverted.

    What could I be missing?

    update:

    I tried an older driver for the PCIe card, but getting the same results. I also disabled the power off setting in Device Manager, but it didn't help.

    A little more info on the issue. Each of these desktops connects just fine, but after a couple minutes, they still show connected, but the Network and Sharing Center diagram shows no connection from the gateway to the internet. There are about 20 other machines connecting through the same gateway and none of them are having this problem.

    All 5 machines are Windows 7 Pro, none of which are joined to the domain.

      So they're just randomly losing connection, or only after going idle? Because there are two separate places for network adapter power settings, and if you only changed one, then the other is probably making it lose connection when the computer goes idle.

        It takes about 2 minutes to lose connection...doesn't matter if I am surfing the net or not. And when I say lose connection, I mean it shows to still be connected to the AP, just no connection to the outside world. I also cannot ping internally when this happens.

        I setup another router as a temporary AP using the old security settings and they works fine. I just can't leave that router in place.

            It's not the gateway. None of the 20+ laptops have connection issues now. They were, that's why the security change was even attempted to start with...to see if it would help with that issue.

              How old is the original AP? Could be going bad? Is the old AP set to DHCP?

                It's a SonicPoint AP (maybe a year old) that was configured as a virtual access point through the SonicWall router/gateway/firewall. We recreated the SSID outside of the virtual settings and it seems to work fine for now with a couple extra tweaks to get the laptops going again.

                  Cool. I was asking about DHCP because I've seen Wireless Access Points giving out bad addresses/duplicate addresses instead of having pass-thru enabled and that can really fuck some stuff up network wise, lol.

                    Seems like that may be a known issue. Maybe this will help some...

                    What about cell phones? Do each of these 25 users connect their phones through this AP?
