Hi,
Just a follow up on Windows 10 ICS issue/fix you've explained so well (thank you!). I connected the Nano to my Windows 10 laptop, it sets itself up just fine and configures the 172.16.42.1 network (which comes up as Network 2 in my Network Connections panel). I can browse to the Pineapple just fine on port 1471. As soon as I set internet sharing on my WiFi network and select the Nano network in the drop down box, it reconfigures the Nano network and shows as an "Unknown Network". I switch off ICS, it comes back to Network 2 again and I'm fine - except I have no internet sharing.
So back to setting internet sharing again. Ipconfig shows 192.168.137.1. So, this is the same problem that you reported. I followed the fix instruictions. I changed the adapter manually to 172.16.42.1 via the IPv4 properties/Advanced, then disabled and enabled the adapter, but to no avail - the network persisted as "Unknown" and ipconfig showed just an 1pv6 address. No amount of disabling and enabling correctedd this. So, this is not the same fix.
I resolved it finally by setting the IP address to 172.16.42.42 - the network continued to say it was an unidentified network, but everything now works for internet connectivity. Anyway, just a bit more information on the issue.
