Windows 7 Pro 64 bit

1) Removed WAN Miniport IP and PPTP adapters ( steps 1-8). Used ccleaner for registry cleanup after removals.

2) Installed Cisco VPN Client. Rebooted Windows and WLAN started to work perfectly.

3) Installed drivers removed on 1) using devcon.exe.

devcon install C:\Windows\inf\netrasa.inf MS_PptpMiniport
devcon install C:\Windows\inf\netrasa.inf MS_NdisWanIp

After reboots system works perfectly.

Windows 7 Ultimate 32bit
Thank you, but not all those steps may be needed

I had a similar problem with an Advent Roma 2001 notebook PC running Windows 7 - its Realtek wireless adapter wouldn't work, with the same diagnostic error message and the usual fixes ineffective; the Realtek Ethernet adapter did work although the device often needed to be uninstalled/re-installed. Installation of the Cisco VPN client fixed the problem - uninstalling the WAN Miniport IP and PPTP adapters wasn't needed. The problem remained fixed when the Cisco VPN client was uninstalled.

Many thanks, this saved me from having to do a repair installation.

Wow -- Cisco VPN install fixed my wireless adapter that wasn't showing

I had tried everything then found this thread. Thanks for posting the VPN install! All I did (after doing all the other steps (resetting TCP/IP stack, replace winsock catalog, release/renew, flush DNS resolver cache) was to search for a free download (Cisco no longer supporting), bring it down, run it, reboot.

wow wow. Who would've thunk. I've spent way too much time on this one but I soooo appreciate your posting the solution!

thanks again.

VPN is the key

Thank you Ron. I came across the usual tortures (reinstall drivers, etc) when I found this thread.
You inspired the solution that worked for me. I had Checkpoint VPN client installed. I just uninstalled it, and WiFi started to work. Reinstall didn't hurt.
Probably managing VPN client adjusts some deeply hidden setting in Windows.

Windows 7 64bit
VPN Solution still saving the day...

It's a good thing these old threads remain...Ron's solution just saved me from doing an arduous clean Windows install that would have involved migrating / reinstalling countless customizations / applications, etc. I spent 3 straight days trying every conceivable solution to get the WiFi working (LAN adapter worked fine) after moving my SSD with Windows 7 64bit from an MSi Laptop with a bad MB into a used EliteBook 8540w. I was preparing a fresh install when I came upon this thread and gave the Cisco VPN install a try...and it worked! Stayed working after the Cisco VPN client was uninstalled.

Joined the board just to say thanks!
