can't connect to internet on new Epox 9NPA+

I've just finished building my first "from scratch" computer, with an Epox 9NPA+ motherboard. Things go suprisingly smoothly. I install windows XP, everything seems to be working....I just can't get online. I'm plugged right into the motherboard, no additional network card. I've installed the Nforce4 drivers, with included the Nvidia ethernet drivers, the other computers hooked up to the Linksys router are working (I'm posting from one), the little green light is on at the back on the PC, and the corresponding light is lit on the router itself. But no internet. What am I doing wrong?

I'm Automatically detect settings, for my lan settings. I've tried other cables (even though I know that one works, and I've tried connecting directly to the modem. nothin'.

Help?
 
I'm going to make some dumb suggestions here, so bear with me:
1) Have you tried assigning a static IP to the computer? Manually entered DNS servers?
2) Do you have a firewall enabled?
3) What happens when you ping the loopback adapter (127.0.x.x)?
 
Have you checked the system properties and see if there's any exclimation points on any items? Do you see the Network adapter installed correctly? If you go to Start, Run and type in ipconfig does it give you an IP address? If so what is it?
 
Plug the new computer into the router, not into the modem. That's a smart idea from a security standpoint. Also, your modem probably is holding its only IP address for the router, which it recognizes by its MAC address.

edit: actually, now that I re-read your post, it looks like you did try plugging it into the router. If you installed the nVidia firewall, turn it off or uninstall it, because it's probably preventing your system from getting an IP address from the router.
 
Reboot the modem and the router, as well as the other suggestions mentioned. Rebooting is as simple as disconnecting the power and reconecting.
 
Thanks for the replies, everyone. Dumb questions are good. I'm clueless when it comes to networking.

I can access the Linksys router through this laptop as normal (http://192.168.1.1), but the new computer can't even get to the router's config page. The DHCP Active IP table, that I'm looking at right now, has this laptop, my roomate's computer, and my old, unplugged computer. The new computer does not appear.

I've installed the loopback adapter on the new computer, and renamed it as such. When I try ipconfig, I get:

Ethernet adapter Loopback:
Connection-specific DNS Suffix . .:
Autoconfiguration IP Address . . . : 169.254.25.129
Subnet Mask . . . . . . . . . . . . . . .: 255.255.0.0
Default Gateway . . . . . . . . . . . . :

Ipconfig /all reveals that Dhcp is enabled.

Firewalls. I've disabled windows firewall. I do not believe I installed Nvidia firewall, but I'm not completely sure. It does not appear as a currently installed program.

No exclaimation points in device manager.

Unplugging and plugging the router doesn't seem to help.

I'm looking at a page on chosing static IPs at the moment, I'm going to give that a try after I restart and look around the BIOS....are there additional firewalls built into the motherboard?
 
It seems like the onboard NIC isn't seeing the router's DNS server, since the router's address 192.168.1.1 and the NIC's autoconfiguration IP Address 169.254.25.129 are not similar. On my network, I have the router assigned to assign static IP addresses to each computer based on their MAC address, which you can get from either ipconfig /all or in the router's DHCP table. Give that a try.
 
Davenp:
Try doing this if you don't want to follow Severian's advice:
1) Right-click on [My Network Places] on your Desktop and choose <Properties>.
2) Right-click on [Local Area Connection] & choose <Properties> again.
3) In the section [This connection uses the following items], select [Internet Protocoal (TCP/IP)] and click the <Properties> button.
4) Enable [Use the following IP address] and you will see 3 fields now available.
5) Assuming you have a generic network setup, enter these values
IP Address: 192.168.1.90
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
- you can actually use any value between 192.168.1.2 to 192.168.1.255 but without knowing the defined IP scope, I'm guessing here
6) Enable [Use the following DNS server addresses] and you'll see 2 fields available now
Preferred DNS server: 167.206.3.182
Alternate DNS server: 167.206.3.183
7) Click <OK> until all the dialog boxes close.
Try the Internet now.

Keep in mind these DNS values are what my ISP uses, so ideally you'd use those corresponding to your ISP. All this is just to test whether or not your Internet access issue is fixed. Normally you would not want to deal with all this for each and every machine, but some people prefer to.
 
OK, I'm learning more all the time here. I have two network connections on this computer: 1394 connection (which is, I only now realize, my firewire connection [stupidstupidstupid]) and the Loopback, which I just installed.

That's all. It would probably help to have a LAN connection, eh? Why, oh why, does windows refuse to create one for me? I go through the network setup wizard, but no new connection is forthcoming.

Severian, thanks for the advice, but I'm not sure how to do it, as the router is still not "seeing" this computer.

My next step, I think, is to pull the old network card out of the old computer, and slap it into this one, even though that solution literally pains me in it's messiness. If THAT doesn't work, I begin to panic.
 
This drives me nuts. A Pyrrhic victory; the network card instantly created a Local Area Connection in my Network connections, the cable plugs in, and I'm online, faster than it takes to type that.

So, for whatever reason, the motherboard NIC wasn't creating it's own local area connection, and was refusing to create one when I asked it to. Why, oh why.
 
I don't believe you've said whether you've done this, but the onboard LAN must be enabled in the bios. What are your settings in the bios for that? I see four (4) NV Lan parameters in your bios (looking at the online manual at http://www.epox.nl/downloads/files/manual/mu-9npa+ultra&+&j.pdf)

The manual is for the entire 9NPA series, by the way.

Take a look at page 41 of 76 in the online manual I refer to above. See what I mean? Are these settings --particularly the NV LA-- enabled?
 
Ahhhh, interesting. No, they weren't. I've set nVidia LAN Control to auto and enabled nVidia Lan Mac Address, so....progress. Still isn't working, of course. I see no reason to enable nVidia Lan PXE Boot Rom.....is there anything else that should be enabled?
 
Follow these steps in order:

A. Click Start/Programs/Accessories/Command Prompt

At the command prompt, type (without quotes put here for emphasis):

"ipconfig /release"

leave a space between ipconfig and /release

Tap the enter key. It will do its thing. When it gets back to the prompt, type:
(no quotes)

Close the command prompt. Do not try to do anything else on the pc.

B. Turn off PC. Turn off the router (remove power cord). Turn off the cable modem (remove power cord).

C. Remove the external nic card in the pc. Do NOT turn the pc back on yet.

D. Turn on cable modem. Wait till the lights sync up.

E. Turn on the router. Give it a couple of minutes.

F. Turn on the pc.

See if you have network access.

(sorry if some of the details you already knew above...just making sure.)
