Hi Matthew,<br>
<br>
LSO was a good hint, thank you.<br>
<br>
Today we did some tests with our "bad" adapters all with current
drivers.<br>
<br>
Intel:<br>
82566DM-2 and PRO/1000 MT are only ok when you switch off LSO<br>
<br>
Broadcom:<br>
57xx does not provide such a switch, we switched off every other
available option one at a time without success<br>
<br>
<br>
Do you have the ability to test such an adapter? You can see
immediately if it is ok or not when you simply copy a 20MB file with
Winscp or any other client which shows you transfer rates. The rates
are very low and change all the time and might even drop completely.
<br>
<br>
While you don't transfer files you might not even notice that there
is a problem. We used our "bad" adpaters all day long with Putty and
thought that everything was ok.<br>
<br>
So now we know that we can add Intel cards to our Broadcom desktops
and switch off LSO to bypass our problem but this is not the best
solution.....<br>
<br>
Regards,<br>
<br>
