Hello Vlk,
Maybe you read the two threads I initiated, and my discussion with Eddy on that topic (last is at bottom of page 3 now).
Now I can confirm that most of software proxies used in perso LANs actually drop the pings, and this causes Avast! to be unable to detect an active connection from a station,
Then if the "permanently connected" option is checked, it actually connects on boot then every 4 hours (it just did now). This is because the proxy software does dial-on-EVERY-demand from any station.
And so this actually yields to choose between updating any station manually, or accepting up to spend a standard 50h/month subscription only for that.
I'm still computing to find an alternative way to detect an active connection on the LAN without forcing it...
Thank you for any suggestion.
PS: Avast! is really good !
Greetings,
