Hi All,I have encountered massive problems with network under Windows 7 RC, both 32 and 64bit.The issue did not occur with Windows 7 beta.(Note: Windows update in the RC performed successfully)- wireless connection drops - the connection changes from "homegroup" to "unidentified"- Internet is accessible, but networking reports "no internet access" and yellow warning icon over wireless signal icon in systrayThings already tried- disable/enable adapter (connections lasts for a couple of minutes, then drops again)- updated latest driver from intel (Intel PRO/Wireless 5300 AGN) - even tried driversfor XP- tried troubleshooting in 7, received almost all possible error messages, problem were solved, however connection drops again after a couple of minutes- unticked QoS - unticked IPv6-...Annotation:Hardware is HP Elitebook 8530p, connection with LAN works. Another notebook with Windows 7 is connected in the same network, connection runs smoothly without any problems (-> so no error in the router).Similar issues are posted in several other forums, e.g. sevenforums.com. There you can find a lot of proposals to solve the issue, however none of them worked. The issue occurs both for wired and wireless network in those forums (for me only in case of using wireless).Best RegardsAndreas

Hi Andreas, I encountered similar problems. Either I had no connection using wlan or connection was established and dropped after a vew minutes. After all it seemed to be a problem of my wlan-stick/driver, because getting a different one and installing/using it, worked fine. Best Regards Axel

Hi Axel,thanks for the hint.I have taken that step already into account as well, however the integrated WLan module is a quite good oneand so Iam hoping to get that issue solved without purchsing an USB- stick...Cheers,Andreas

Did the issue occur after you installed Windows 7 RC, or it started to occur recently? I suggest that you temporary disable the anti-virus and firewall, then delete the WLAN connection and recreate it. Please note that do not use any third party WLAN manage programs. If the issue persists, please download the latest driver from HP website. It should be the most compatible driver for Windows Vista the device.

This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information. Before installing the new driver, please go Control Panel\Program and Features and uninstall the current driver. If the issue still occurs, I suggest that you run In-place Upgrade to repair system components. If the above suggestions do not help, I am afraid that the network adapter is not compatible with Windows 7 RC.Arthur Xie - MSFT
