Issue #2182 has been updated by Ferruccio Zamuner.

Description updated


this bug is still active, today I'm on the customer LAN where the problem happened last october and it happens again, also today.

Sometime ago, I've followed the dillon's hint to put a router between the LAN and my laptop, but it didn't fix.
