Turn Off ALL VPNs:

Are you using a VPN, here?If so, turn it off.


Single-Out this User:

Create a new Administrator user, and see if you get this same error. If not, then it is an issue with your current user. If not, then it is a system wide issue.

Thanks, we are solo here, no VPN. I am hearing the power port can overdrive the multiport, so have that on the 1st port now. Trying to get that 2nd port with the Powlaken recognized. Still no joy.. I just moved so have great wifi. Other than watching a movie on the tiny big screen on HDMI. Thanks for help!!!
