    The "Eethenet keeps dropping" conundrum

    I installed Xubuntu 18.04.3 on an HP Elitedesk 705 yesterday, and the ethernet connection kept dropping. I have been running Xubuntu since 9.04, and have never had this problem. But it's apparently not uncommon these days. I finally got it to work by editing network/interfaces as described here (and after fixing an unmanaged network error after I edited the file).

    So here's my question: I am running Xubuntu 18.04.03 on another machine, a Kingdel, which I installed shortly after 18.04 was released. It has never given me any problems, and the ethernet has always performed flawlessly.

    The ethernet hardware (assuming I interpreted lshw correctly) on the Kingdel is a Realtek RTL8111/8168/8411, but it is a Broadcom NetXtreme BCM5762 on the HP. Where do we go from here? Do I file a bug report? Do I post here and hope someone can explain what's going on?

    Thanks, as always, for your advice and insight.
    We've come a long say since Xandros and the Asus Eee 900, haven't we?

    Below. Currently, I don't have the cable in and all seems to be working with a Realtek USB dongle.

    We've come a long say since Xandros and the Asus Eee 900, haven't we?

    Thumbs up Re: The "Ethernet keeps dropping" conundrum

    Mark it solved. Don't know why I didn't think of this earlier. I attached a $13 RJ45 USB ethernet adapter to the ethernet cable, and then plugged it into a USB port. I have a 1 gigabyte connection using the asix driver, and it has bypassed the Broadcom network card.

    So far, so good. The ethernet connection has been running constantly for two days with no dropped connections, and I have tried to get it to drop.
