Hi all,I'm having trouble connecting to wireless networks. Seems I can't connect to a wireless network through the UI without manually creating a wireless network profile first.Normally, when I would double-click on a wireless network from the list of available wireless networks,Windows would prompt me to enter the passphrase (if the network was secured). If the network was unsecured, Windows would warn me about unsecured networks and give me the option to connect anyway. After connecting to the network, Windows would give me the option to save thewireless network andthe option to connect automatically to the wireless network when available.Instead, what's happening is that when I double-click the name of the wireless network to which I want to connect, Windows instantly displays the message "Windows cannot connect to [network name]". I have 2 options: Diagnose the problem, or Connect to a different network.If I choose "Diagnose the problem", the response from Windows is: "Windows is not set to automatically connect to [network name]. You need to select a wireless network and connect to it."If I manually create the network profilefirst and manually enter all of the information about the network(SSID, authentication type, key), then Windows will successfully connect to the wireless network.I have tried connecting to several different networks and the results are consistent. I don't want tohave to manually setup a connection profile for every wireless network I want to connect to. Windows should allow me to connect to a network from the list of available networks without manually creating anetwork profile first.I have installed the latest drivers for my network card and tried the registry fix of adding the DhcpConnEnableBcastFlagToggle DWORD value.I am using Windows and not third-party software to manage my wireless network card.Below is some information about my setup. I would be glad to provide any additional information. Any help would be appreciated.Systeminformation:Machine: HP Laptop tx1220usOS: Windows Vista 64-bit, SP2Network adapter: Broadcom 4321

Here is some additional information from the WLAN-AutoConfig event log:Event ID 8000: WLAN AutoConfig service started a connection to a wireless network.Network Adapter: Broadcom 4321AG 802.11a/b/g/draft-n Wi-Fi Adapter #3Interface GUID: {45410e13-0c36-4769-abb7-068c4c98ddd0}Connection Mode: Connection to a secure network without a profileProfile Name: NetgearSSID: NetgearBSS Type: InfrastructureEvent ID 8002:WLAN AutoConfig service failed to connect to a wireless network.Network Adapter: Broadcom 4321AG 802.11a/b/g/draft-n Wi-Fi Adapter #3Interface GUID: {45410e13-0c36-4769-abb7-068c4c98ddd0}Connection Mode: Connection to a secure network without a profileProfile Name: NetgearSSID: NetgearBSS Type: InfrastructureFailure Reason:The specific network is not available.

Hi, Thank you for your post. If everything worked previously, you may try restoring the system back to the previous status when the issue didnt occur with System Restore. (Note: Performing a system restore may cause the loss of the current system settings; therefore, before doing this, please make sure that the system restore point is not too old and set a restore point for the current status.) To make the issue clear, please let us know if all the wireless networks fail to be connected by double-clicking them? If not, please provide us the detail information about the connections, such as authentication type. Based on my research, I would like to suggest the following at this time: 1. Check the wireless network signal strength. If it is not strong enough, this may cause the network disconnection issue. 2. If you use third-party software to manage the wireless networks, please remove it and just use the Windows built-in utility. 3. Upgrade your Wireless NICs driver. You can also remove and reinstall the Wireless NIC. 4. If you have a removable Wireless NIC, please disable the Broadcom 4321 card, try to the removable one to access the wireless network and see how it works. 5. Ensure that all the updates for Windows Vista have been applied and try the following hotfixes: Several problems occur on a Windows Vista-based computer when you work in a wireless network environment http://support.microsoft.com/kb/932063 An independent hardware vendor (IHV) profile may be unable to establish a wireless connection by implementing a third-party EAP method on a Windows Vista-based computer http://support.microsoft.com/kb/952613 Hope this helps.

Thanks for your reply. This issue kept me up very late last night, but I eventually identified the culprit. The problem seems to be with my AV software Symantec Endpoint Protection. Specifically, I was running SEP version 11.0.4014.26 MR4 MP1a. I had previously tried disabling SEP, but that didn't solve the problem. Then I used msconfig to disable all non-Microsoft services from starting up. This still did not solve the problem. Finally I bit the bullet and completely uninstalled the SEP software. After a reboot, Windows was back to allowing me to connect to wireless networks by double-clicking them in the list of available networks.For now, I am using a trial version of OneCare Live until I can get an updated version of SEP. A fellow co-worker has the exact same laptop as me, but he is running the 32-bit version of Vista Ultimate. I'm curious to see if this problem is isolated to the 64-bit version of the OS, or if it affects both the 32-bit and 64-bit platforms.I installed the SEP software prior to upgrading to Vista Service Pack 2, and I could connect to wireless networks without any issues. So this version of SEP apparently doesn't play well with SP2.I will follow up to this question when I find out if this problem also occurs on the 32-bit platform.

Hi, Thank you for update. I am glad to know that you have found that Symantec Endpoint Protection conflicted with this feature and led this issue; after removing Symantec Endpoint Protection, it worked. At this time, please monitor this issue and keep me updated. Meanwhile, I would like to share this document with you. Hope this will be helpful if you meet some related issue in the future.
