I have experienced this problem and it doesn't appear to be consistent, some days it would stay on for ages and others it wouldn't. Also, sometimes it would reconnect very quickly, other times it wouldn't. I have tried altering the settings in my firewall and in Windows, as suggested by various posts, none of them provided a permanent fix.
The solution for me was to buy a USB-A/ethernet adapter, for very little money, and everything has been rock solid since then, absolutely no issues. Hopefully Line 6 will sort this, and add USB capability, in a future update.
