Hi All,

Wasn't quite sure how to title this one...

We have a few hundred wireless laptops; they are configured via group policy to use 802.1x certificate-based authentication to connect to our wireless network. This works pretty much flawlessly for devices that remain on the premises or that are used regularly on our network.

We do however have some machines that go home with staff and do not connect back to our network (in any fashion, no VPN, etc.) for a few weeks at a time. They seem to be losing their 802.1x settings. I thought perhaps the machine certificates were expiring but that's not the case. Connecting via the wire then forcing a gpupdate refreshes the settings, at which point they will connect wirelessly.

Any ideas or suggestions as to how to attack this?

Thanks,
James

Does it happen to every laptop that goes home or just some, of them?  Are the laptops in question connecting to home wireless networks during that time?

Sorry, I totally lost track of this thread.

The issue here is we have a very limited number of devices that go home, and they happen to be in use by people who are hard to work with (time-wise). So unfortunately I have very little troubleshooting info to go by. That said, I'm not convinced there's actually a problem. It seems if the machines are in sleep mode (at home let's say) and brought into our network, they don't always see the WiFi. A reboot seems to correct this when it happens - at least anytime I've seen it.

If a reboot solves it, I guess you're right. It's really not a problem. Disable sleep mode & hibernation on one of the laptops & see what happens.  I never saw any value in those features anyway.

Out of curiosity, what OS?
Are they new installs or in place upgrades?
