The fact an older system works doesn't necessarily mean a new system will behave the same.
You may want to just wait until Tuesday to see if the new Win 10 build comes out.
If you want to try to reset it, what I do is download the appropriate driver for the Wi-Fi card. Have it available and then go offline. While you are doing this you may want to shutdown your other network devices and restart them before you go back online.
Use the Device Manager to uninstall the Wi-Fi adapter and check the box to uninstall all drivers. Once that is done an possibility after a reboot, install the downloaded driver. Once it is installed, go back online and hopefully, your problems will stop.
There are literally hundreds of threads with folks having problems regarding losing their network connections.
