Specs: Windows XP, Pentium 4/2gb

ethernet connection. have a built in lan but
used another ethernat card to check, both
didn't work. I did ping the loop-back address
and got 4 x "reply"

... go to "start" run (type) devmgmt.msc [press enter]

... do you see yellow marker by network adapters?

... if so it may require driver reinstall ..... also try:

... insert XP CD

... from cd menu click "install optional windows components"

... [OR go to control panel add/remove programs add/remove windows components]

... check "networking services" [also double click it]

... check "internet gateway device discovery and control client"

thanks for the reply mavis007.
the adapters are green... configured and working properly.
the drivers are good...
now I checked the "networking services" and check boxes are clicked under "internet gateway device discovery and control client" and "Simple TCP/IP Services"
I read that some people had the same problem but I yet to find a solution...
Anymore ideas? Anyone?

I'm no expert on the matter, but the lack of a default gateway suggests that it doesn't even "see" a modem or router.


How exactly is this meant to be setup.

computer > modem > internet
computer > router > network > modem > internet

Is it all supposed to be auto configure?

What type of wired internet connection?(dsl, cable...)

This may be a stupid question but have you setup a separate connection in windows for the wired connection? (i.e do you have two connections listed in the under the network folder of the control panel).

Presumably you have enabled wifi service in the router? Often it's disabled when first set up and then again sometimes it's there by default...? Either way have you verified (iia wired lan connection) admin accesss etc. that wifi is actually active/enabled on the router?

Hi,

Two points to note from the connection information you posted:
1. No gateway address
2. Address of your wired network interface card (NIC) is in the range 169.254.*.*
These addresses are created by the operating system on the PC, hence the 'Autoconfiguration', and no connection to the network.

These two items indicate that your wired connection is not able to reach the router. Because it can't reach the router, it is not able to get a Gateway address or a valid network IP address. The NIC itself is working. (BTW the different physical address is expected - this value is typically unique to each NIC)

If the USB connection that works is wireless, then this suggests that the problem is in the wiring of the LAN or the router setup for the LAN.

Regards

Thanks to everyone who responded. I couple of points. I have
a cable modem and I can plug lan wire from it to my another
computer (laptop) and internet works just fine. I can also use
usb cable to connect desktop PC to the cable modem and
get internet connection. But I can't get internet connection on
my desktop PC via LAN wire to the cable modem. There is,
you know, a yellow exclamation mark that says limited or no
connection status. So it doesn't see the cable modem as
someone suggested. The NIC is working... What can it be?
Any more ideas?
Thanks

completely normal, well except for both wired and usb working at the same time. What ips do each get? Same?

laptop nic mac is registered with the isp.
your desktop nic is not [one mac per registration]

either put in a router and clone the laptop mac to the wan interface or get the mac of your laptop [ipconfig /all note the physical address] and then put that address in the pcs nics advanced properties/locally administered address so you can spoof the isp to think your pc is your laptop.

Oh and don't connect your laptop to the router wired AND usb to the modem or your laptop will get the routers wan ip and nothing connected to the router will get internet. Both laptop and pc should be connected to the router. Router connects to the modem only.

Or get an access-router (modem and router combined in effect); as that will allow much it all to happen very easily. And this all is more or less automatically - once you've done a few minor things at admin level via the access-routers home page...

One either has an all in one "box" - an access-router that has (as I mentioned above) both a "dsl modem" and a router - to share access to the www built-in; or one adds in a router (no modem included) and sets that up to shre the isp and the rest... An access-router is the easier and generally preferred/accepted path nowadays?

I'd spend the pennies and get an access-router...; so much easier overall...?

wanderer and trvlr... I'm not sure what you're saying... I don't
connect two computers to the cable modem at the same time.
Never did. I never connected my desktop pc via both usb cable
and lan cable to the cable modem at the same time.

When you have dsl service (cable or phone-line style) you usually assigned and pay for one ip address. When you connect your system (any one pc) up the first time...
(as Wanderer comments) that system's nic details (specifically its mac address) are in effect hard-coded into the service providers files... Any other nic will not be recognised and thus it won't/can't connect...

It doesn't matter if you are using cat-5 or wifi - or usb for that first setup; that is the nic that is registered etc... Any others thereafter won't be "allowed in"...

Professional/business users often pay for several separate ip addresses...; each a unique account for "one" nic/system.

Obviously it can cost £££/$$$... so the other way is to insert a router into this system and share that one registered ip address around all required systems...

One can have the modem connected to the dsl service and feeds into a router; and all systems are connected via the router to the isp. The router has a "clever" bit of kit/software that includes something called network address translation (if I remember correctly) aka NAT. This is the means by which the router "spoofs" the connection to allow that one registered mac address to serve many others... That router is the "gateway" through which all systems can go to access the www....; they in a sense masquerade as one registered system (mac address).

Setting up the two separate bits of kit to work correctly is not hard to do; but takes a little more time and know-how? Using an all-in-one item is much easier and generally the preferred/recommended path to go. With the modem and router in the same case/unit the set up is very easy and quick...

Either method will work - but the access-router is easier to setup (for most folks); and I suggest you go get one as it will allow you to have more than just one desktop/laptop to use your dsl service - at any time..

I have an Alcatel Speedtouch 716g (cat-5 and wifi enabled) and find it fine. Others will prefer and suggest/recommend other makes and I suggest yo seek others thoughts re' which to use? And maybe do a brief trawl for reviews of current models etc.?

Hi,

I see that your USB connection is wired (ethernet) and as it works, then the LAN connection itself is OK.

Connecting this same cable to the onboard Network card on your PC does not work.

As the onboard connection has an auto-configure address (one that starts with 169.254.*.* ) then there is likely a problem with the setup for the on-board connection.

I suggest uninstalling the on-board network card, and letting XP re-install it. Use device manager, select the on-board network card and select uninstall. Restart XP and let it discover the new hardware.

Try the connection again.

As a separate issue I note that you are connecting direct to the cable modem.

A relatively cheap router will allow you to have more than one PC or laptop connected to the Internet through your cable modem, at the same time. It also provides additional protection through the router's firewall.

Regards
