Re: Vista client lost connection to secure wireless network ?

Hi Dave,

We have found that we face a driver issue here:

We reinstalled the PCs with XP: works fine so it can't be a bad NIC issue
We tested the PCs with Vista and another NIC (spare PCMCIA Linksys): works fine

We'll contact Dell to check if they can provide us with some other driver or we will see if we can order Intel NICs and put them in the laptops.

Thank you for your help,

Xavier

In the wireless properties on the laptop - you should see a list of wireless networks the PC has connected to, with your local wireless at the top. Just deleted it from there (sorry, I don't have wireless on this box to tell you the exact steps to get there).

If your implementation is working on the rest of the PCs, please resist the temptation to change anything on the server or the WAPs. Last time I ran into this on a Dell with Intel NICs, it was a bad NIC. The laptop would connect flawlessly to my guest network (unsecured), but not to the secure network that's configured according to Owen's documentation. I ended up talking Dell into replacing the NIC, which fixed it. I've also had driver issues and, occasionally, a cert issue. If it's the cert, you should see auto enrollment errors in the application log on the laptop.

I don't know how exciting a prospect this is for you, but one idea might be to swap the NICs between two of the laptops. If the problem follows the NIC, you'll know for sure. (If these things all have the same NIC driver, you can easily rule that out as well). At least on the ones I've worked on, changing the NIC is easy if you follow the documentation.

Hello Susan,

By "deleting out that Wireless network config for that specific configuation and set it up again" do you mean flattening out the AP configs, the IAS configuration, etc. and redo all that configuration work ? That is going to ask some time and effort that can only be planned for a week-end. If you mean deleting the configuration on the PC itself, this has been done a couple of times and it didn't help.

What drives me crazy is that the whole configuration is pushed through GPOs and as worked flawlessly for 2 years. Over time we have added a few laptops to the original network without any issue. In the mean time I found the exact translation of the error message: "*** the capability of this network adapter does not meet the requirements of this network ***" and if I check the adapter I do find back WPA-Enterprise, TKIP, etc... which are the technologies used by the infrastructure.

Hello,

Customer network description: SBS2003 Std SP1. 2 NIC configuration. 2 CISCO Aironet Access Points. Wireless secure network configured as per Owen Williams whitepaper ( http://home.comcast.net/~clearviewtc/ ). 15 wireless clients (14 XP SP2 and one Vista) have been using this network without any issue for 2 years now.

We are adding to this network 4 new laptops. These laptops are Dell Latitude D531 (with Dell Wireless 1395 802.11 b/g). We have installed Vista SP1 from scratch on these systems along with the latest drivers from Dell. We have joined the systems to the domain and added them to a group called "Wireless Domain Computers". Thanks to that, upon reboot, the system do get certificates and wireless configuration. At that point it can connect to the secure wireless network. So far so good. But here comes the weird issue we're facing: we have switched on and off the wireless button on the laptop. Since we've done that, the computer does not connect to the wireless network anymore (even after several reboots).

When looking at the adapter in the network sharing centre, we do see the following message (approx. translation from French): "The parameters registered on this computer do not correspond to the required configuration for the network".

We have re-re-installed one of the computer, we have installed the latest network drivers, we have successfully tested the wireless card with a test (wep protected) wireless network.

I must admit that I am now clueless. Any hint, help or pointer would be highly appreciated.

Sounds like you need to delete out that Wireless network config for that specific configuation and set it up again.

I see that type of error when I've had a saved config for a Linksys and then I try to connect to another Linksys and the security settings are different.

Not on the server side, I'm talking about on the workstation side. There's a saved config on the workstations that sounds like it's gotten corrupted.
