Do you mean Ethernet?
Feb 22, 2006 4:32AM PST

The answer is probably yes if it doesn't have one already built in. As for type, it depends on what your laptop has slots for, but it will likely be some sort of PCMCIA card. You could probably also get an ethernet to USB adapter dongle, but if the unit's old enough not to have an ethernet controller on the motherboard, the USB ports are bound to be old and slow.

What is an Earthnet LAN card"?
Feb 22, 2006 5:09AM PST

Perhaps you meant an Ethernet card (you can include "LAN" in there too, but it is not necessary).

If you have a cable modem, as you say you do, then your laptop has to somehow connect to it. It might be via a USB connection, or a hard-wired Ethernet interface, or a wireless Ethernet interface.

Whichever it is, then, yes, you do need the matching interface (USB, or Ethernet card, or wireless Ethernet card).

USB Cable Modem Driver CD

Did you get and load into your laptop the cable modem driver that came with your cable modem. You have to load it first, then connect to cable.

Not necessarily
Feb 23, 2006 4:02AM PST

At no time did shclarkson ever say that s/he was using a USB cable modem.

As for any ''cable modem driver'' needed to be used otherwise, it just isn't necessary at all, and there probably isn't one anyway.

I have used my laptop, and my other computers, at many other locations with wired and wireless Ethernet connections; with that network never ever seeing me ever before. Nor had my computer ever used their cable modem, or any model of that brand, before. I just plugged in (for a wired connection) or just turned on and searched for a wireless signal.

No drivers were necessary for that modem (cable or DSL) simply because the only drivers needed were to get my Ethernet connection device (either my internal Enet card or my WiFi card) working. The actual Ethernet connection does not care what it connects to, either a cable modem or whatever, as long as the Ethernet responder device supplies an IP address to my computer, that is all that my computer cares about.

More than likely, shclarkson just has to set up his/her computer to use DHCP (Dynamic Host Configuration Protocol). That way, any Ethernet connection found automatically sets up for requesting an IP address.

If shclarkson ever responds and fills in some additional detail, such as what sort of connections are being used, what OS s/he is using, perhaps even a model of cable modem being used (which would make some needed answers self-evident) then we really don't know enough to start giving more exacting answers, at this time.

Come on, shclarkson, give us some details.

Well........
Feb 24, 2006 6:50AM PST

I don't quite know what to say, Chuck. You see, when I first acquired a cable modem, from Time Warner Cable, they gave me a cable box and a CD. When I hooked it up the first time, it didn't work, and then I remembered the CD. I loaded the CD and then reconnected the cable modem and it worked. A couple of years later, when I complained to Time Warner cable about the 'speed', they told me I had an ''old'' cable modem box and to come get a new one. When I arrived they not only gave me a new cable modem box but also a USB Cable Modem CD. I have done two clean installs since then, and every time I have to install the drivers from the USB Cable Modem CD. To the point that I no longer download and install the drivers for the Broadcom that came with my Dell Dimension model 2350 computer. In fact, in the past I have disabled the Broadcom from the control panel/network connections because it wasn't being used and then deleted the icon from the system tray and uninstalled the Broadcom/Ethernet controller. I guess we have different computers.
Hopefully Shcarkson has already fixed his/her problem or report back that he/she still needs assistance.
Have a good weekend

We just don't know what sort of cable modem s/he has
Feb 24, 2006 10:58AM PST

You were assuming that the cable modem mentioned was a USB connected modem. We do not know what sort of modem is being used, and that is why I asked shclarkson to give us some details.

Even if it is a modem that has a USB connection, it may also have an RJ-45 connection, too (as mine has both). But we still do not know what sort of connection that s/he is using.

A USB connection to a cable modem may require a driver for the modem, especially if the OS s/he is using is not WinXP. If s/he is using WinXP then, with many main stream devices, the required USB driver may already be present in the WinXP library. And WinXP is usually pretty good in getting a USB device working, at least to a rudimentary level, enough so that the device can function - maybe not up to full capabilities, but working, at least.

Until shclarkson actually comes through with some detail, it might be best to not confuse him/her with searching for things that may not be pertinent.
