100 mbps Ethernet LAN


T

Thomas Love

I have finally gotten all the components of my two-
computer LAN up to 100 mbps compatibility. The LAN status
still shows 10 mbps. Are there some settings that I'm
missing somewhere? I have two computers connected by a
10/100 hub. Each is connected with Cat5 cable. Each has
a 10/100 nic. There is a dsl modem connected to the
uplink of the hub via its own Cat5 cable. All networking
facilities work fine -- at 10 mbps.

What can I do to get the two XP systems to recognize the
100 mbps status?

Thanks.

It's possible the DSL modem has a 10Mbit LAN
connection, and that's forcing the hub down to 10Mbit.

Try unplugging everything except the 2 PCs, and re-booting them.
Do they pick up 100Mbit now?

Ron, thanks for the suggestion. The DSL modem, however, has
indicators on the
front panel that light depending on whether you are on a 10 mbps or
100 mbps network, so I assume it is designed to accommodate 100 mbps.

I still think it must somehow be something wrong with the built-in HP
computer's adapter --> HP EN1207D-TX PCI 10/100 Fast Ethernet Adapter
or something wrong in my settings for the adapter or the network on
this
computer.

Thanks.

Go into Propertines on your NIC card Click on Configure and look for
an Advanced tab. This should show you a long list of obscure
settings. Look for Link Speed and Duples settings. They are normally
set to "auto"

Dirvers are specific to the brand of NIC so I can't give you
a more precise description.

I have tried the speed settings on the network adapters. Both
computers are set to Auto Detect settings. When I set one manually
to 100 half-duplex it accepts it okay. The network still works, but
still shows 10 mbps. When I set the other computer to 100 half-duplex
it reports the "network cable is unplugged", and fails to operate on
the network. (I have interchanged cables to assure that the source of
the problem is not the cable.) This is the HP computer with the
HP EN1207D-TX PCI 10/100 Fast Ethernet Adapter. It may be possible
that this driver is simply not fully compatible with XP and/or not
really capable of 100 mbps operation. I've checked for more recent or
better drivers to no avail.

Any other suggestions would be greatly appreciated.

If the computers are close enough together, try another cable,
maybe a long factory made patch cable.
