Okay, when Windows 10 was first installed we (W10 and I) somehow changed my username to my email address, don't remember why, so now I can log in to my other computers.
One of my other computers received the AU last night and it works just fine, can log into my Ubuntu box just fine. So I brought the Acer up to my office and connected to the network via cat 5 instead of WiFi and was able to connect to Ubuntu.
Disconnected the cat 5, turned WiFi back on and rebooted, no access to Ubuntu, now this is getting to be complicated, my Acer is normally in my workshop, so there's a range extender half way between my office and shop. Connected to my office WiFi I can access Ubuntu, connected to range extender I can't, Windows Explorer sees it but won't connect, "Location is not available". Time to contact D-Link.
Thanks everyone, for your help.
I don't know if the problem you're having is like the problem I had earlier today but if it is, then this video is a lifesaver!

Spent over an hour with D-Link without a solution to the problem of accessing my Ubuntu computer, don't know if it's a Windows 10 AU problem or a combination of AU and Acer Aspire, so I've given up, the fact that I can get to my other computers is really all I need.
Try reseting the Gateway and see if that fixes it.
As mentioned in Post 15, I've given up, it was the other computers I was concerned with and it turned out to be mostly my mistake
We are always correct about the so called support people for equipment, same as at Best Buy. You have the best support here on this forum. The troubleshooting is the hardest part when you are frustrated and do not know how to pin point. That is why we always ask first if a user has checked bios, Gateway/Access Point.
Linux Live CD/DVD allows us to confirm if it is a Bios, hardware or gateway related issue. Since the problem on that machine is the same with both OS's, then you should just do a Reset of the Gateway, which flushes the IP Table and removes any other types of restrictions on it.
