No internet connection after upgrade

I do have the Cisco client installed. I've reverted the upgrade. I'll uninstall the Cisco client, upgrade again and report back.

I had another VPN client installed, but already wiped it completly from disk, run CCleaner, did stuff like "netsh winsock reset" and "netsh int ip reset", fully purged the adapter from the system, installed the shipped drivers and official Intel drivers. Tried DHCP and static. I did this for all THREE adapters (one wired, two wireless). They are all shown as working in the device manager, I can change all their settings and everything. But I do not get any network connections. Diagnosis always says that IP protocol stack could not be bound.

Did you wipe the VPN in Windows 10 or the previous version of Windows?

I wiped it in Windows 10 (full uninstall, followed by CCleaner, reinstallation of the network adapter, running "sfc /scannow", reentering all settings).

But I have it working now: I simply RE-installed the latest version of my VPN client on WIndows 10! LAN worked instantly again!

This has fixed the issue for me. It appears any VPN clients need to be removed before upgrading.

So someone over at a surface pro forums stated uninstalling the cisco vpn client when in windows 8.1 then upgrading seems to fix the network problems.

that might have been great to know before the upgrade, but what if we already made the move with cisco vpn?

what other forum?

Can anyone provide a copy of the new Cisco client? I had the old one installed previously. So it should have been removed in windows 8 and shouldn't have been there in windows 10 but I'm guessing because of this mine isn't working.

I have an older version of the Cisco VPN client as well...reverting to 8.1 and removing and then going back to 10...will post results.
