Subject: [OS2NetWare] Re: Two NICs w/IPX bound; second doesn't work

Thanks, Michael. Yes, I should have thought of this. It's actually in 
the inf:

     NetWare Client for OS/2 sends out a destination query only on the
    primary network board. It never queries the secondary (or other)
    board for a route. If NetWare Client for OS/2 doesn't find the
    destination using the primary network board, you see a connection
    error, even if the destination could be found using the second
    network board. (However, the network on the second network board can
    be queried using IPX calls from a custom program).

    Once NetWare Client for OS/2 finds a destination using the primary
    network board, it stores the route to that destination in a router
    table and makes a connection.

    After a connection is made, NetWare Client for OS/2 checks all
    networks connected to that destination for other possible routes
    from your OS/2 workstation to the destination.

    If it finds a secondary route, NetWare Client for OS/2 rebuilds the
    router tables and stores that route. If the primary connection
    fails, NetWare Client for OS/2 will use the secondary route to
    continue transmissions to that destination.

    If NetWare Client for OS/2 is using a route through the second
    network board, the primary connection can be broken without causing
    the secondary connection to fail.

    However, the secondary network board never becomes the primary
    board, even if the primary board fails. This means that if NetWare
    Client for OS/2 needs to find a new destination while the primary
    connection is down, it can't query for the destination, since
    queries are only sent on the primary.

And there I have it. I suppose I could make the Wi-Fi the primary board 
by loading it first, but of course, this means that it must always be on 
(and physically inserted in the machine). Other than that, I may just go 
back to my dual CONFIG setup.

Thanks again for the reminder of what is obviously the problem. To prove 
it, I should log in via the cable, and then disconnect. If everything 
works as we expect, I should maintain my connection via the Wi-Fi when 
the primary goes down.
