Homegroup not working

[Sylphia]

I've returned my former buggy AC66U and swapped with a AC68U, and fixed that issue.

But same as the AC66U, I can't get Windows 7 homegroup working, regardless of wired or wireless. One pc created a homegroup, but the other pc could not see it. I've enabled IPv6 tunnel6to4. All other networking were good except of homegroup, any idea?

Check your firewall settings. It isn't the router.

Also make sure everyone is connected to the same network (i.e. that you don't have some of these set to a Guest network), and that you have AP Isolation disabled on the Wireless -> Advanced page.

Thanks.
Cleared nvram and the problem is gone.
But I've reproduced my former AC66U issue. Import a openvpn config and start openvpn client, then wifi country code was gone. Seems setup openvpn manually avoided this problem. I'm not sure if it's related to the content of my ovpn config file, it has many lines of routes.
