unplug the other computers from the hub. now unplug the broadband
modem and plug it back in. Power on the problem pc. BTW, if you try
a static IP, you need to configure the default gateway. check one of
the other machines that is working for this. but don't do that until
you try DHCP. what about my other question?


I'm using Bell Sympatico, and the modem is an Alcatel SpeedTouch Home.
The modem is connected to the uplink port of my hub, and this allows
me to share this Internet connection among all the PCs that are
connected (each gets its own unique and dynamic IP-number as soon as
it logs in).

I tried the shutting down and unplugging method, but that didn't
change anything.
(While I was at disconnecting stuff I tried once more to hook up the
problem PC directly to the modem, and again, it connected immediately
without any problems.)

As far as the default gateway is concerned - it's not defined on any
of the other PCs either, so I wouldn't know what to set it to...
Here, for example, is the ipconfig output of my main workstation:

Windows IP Configuration

As far as the firewall is concerned - only the Windows firewall
exists, and it has been disabled.

I also tried (once more) to install newer drivers for the network
card, and this time (perhaps because I did the uninstalling and
rebooting in a different sequence) it showed *some* effect! I now can
actually see some of the servers on the network. I was even
temporarily able to see the shares on one of the servers, but that
went away again. I still can't log on to any of the servers, or ping
them, or see the laptop on the LAN, but at least *something* has
changed...

Normally, whenever I hook up a new PC to this network, all I have to
do is to define the workgroup name, give it a unique IP-number, and
I'm on my way. But this time I've been struggling for three days now.

I read somewhere that I should change my NIC speed/duplex mode if I
use a hub, and I tried different settings (right now it's at "full
autonegotiation"), but the only effect that had was that I'd get a
"network cable disconnected" if I selected any 100mbps option.

Stacy,

You have fallen victim to the plague of loose language that infests home networking. You think you have a "DSL modem." Actually, according to a manual I found for the Alcatel SpeedTouch Home (http://www.grandecom.net/site-file.php?fid=37), this device is a DSL modem that includes DHCP server. It must also include a router of some sort, but the manual is less than clear on this point. The DHCP server may or may not be on. If you are seeing local addresses of the form 192.168.0.x, and you are not manually setting these for each computer, I suspect that the DHCP server in the "modem" is on.

Your equipment is, unfortunately, fairly obsolete: it only supports 10Base-T Half Duplex.

So, as Barb suggested in her last post, set your new laptop to 10 megs half duplex.

If changing the settings on your NIC fixes things, great. If not, I hesitate to suggest things without knowing how your "modem" is configured. Your "modem" is a lot more configurable than most home routers sold today. Fortunately, the manual seems pretty comprehensive. It also says more info is available (although this product seems so old to me that the other "User's Guides" may no longer be available):

The STHome is an advanced product. Describing everything in
detail goes beyond the perspective of this User's Guide.
However, in case you want to explore STHome's possibilities and
interfaces in deep, you can always consult other Alcatel Speed
Touch DSL product's User's Guides available from Alcatel's
Support website at:

Out of curiosity, when you want to connect to the Internet, do you have to enter a userid/password to "dial" your DSL service, or do you just start up your browser and type in an URL?
