Are you using some kind of antivirus software? If yes try to disable it.
does built-in windows defender count as antivirus? I have an antivirus software + full fledged firewall (Kaspersky) on my laptop witht he same windows 10 Fall Edition (1709) - working fine, with no drops in internet.
I already disabled windows firewall just in case.
I ran the following commands
netsh winsock reset
netsh int ip reset
netsh advfirewall set allprofiles state off
Also I noticed that after internet disappears in my nuc, nuc becomes inaccessible in my NETWORK (I cannot open shared folders from my laptop), but I also have setup HOMEGROUP, and even though network is down on nuc, I can still open shared folders from HOMEGROUP.
Just for test, can you disable your antivirus software only to check if this software is not blocking your internet?
well I disabled windows defender, windows firewall, tcp/ip6, power saving options for all network adapters (both LAN and Wireless),
I also disabled HOMEGROUPs on all computers, now it looks like that probably HOMEGROUP was the cause of the problem.
NUC is now lasting longer on internet connection. I need some more time to confirm this (there were frequent power cut-off in my area, which might also affected connectivity)
disabling HOMEGROUP did not help.
Looks like the problem is in DNS server, will try to set it manually to Google DNS servers
1. What you thing about disabling in BIOS and/or uninstalling Intel SGX driver?
2. Is your chipset driver updated?
well I installed all drivers from Intel website for my NUC and updated with new ones, so chipset should be in that list
About BIOS could you pinpoint where in the menu I should look for such options to be disabled, as I am lost in such new BIOS menu.
What is SGX driver and what will I lose with uninstalling it?
Intel SGX is an acronym for Intel Security Guard Extension technology. It is software library enabling software application developers to protect code in isolated parts of memory. Better and more adequate explanation you will find here:Intel SGX Homepage | Intel® Software .
The Intel SGX can be enabled or disabled in BIOS: Advanced -> Security -> Intel Software Guard Extension (SGX)
I'm not using the Intel Driver & Support Intel Assistant to install my drivers (since I think is not reliable enough yet), rather I'm installing my driver manually, after downloading from Intel site: Downloads for Intel® NUC Kit NUC7i5BNH .
If you are not sure that Chipset driver is installed, download it and install again.
I'm advising you to uninstall/disable the Intel SGX, since to much protection can be cause to Internet disconnection. Any way you can try this, and if doesn't help you can reinstall this driver if you want this future.
Thanks, will sure try disabling SGX in BIOS. Will report if it did helped to my problem. (Some update: I did inputed Google DNS servers into wifi router and assigned permanent internal ip address for nuc in the router settings - now internet connection lasts much longer, but problem still exhibits somehow after sometime)
I did downloaded drivers manually from the same Intel website, so chipset driver I sure did installed (actually it was the first driver I installed after installing windows)
