If my network drivers installed fine, why do I have no network access?

I'm usually pretty ok at putting pc's together from a pile of parts but this time I'm wondering if I have a defective mobo. Just got an Asus P5B and fired it up after assembling. Everything was fine, Windows installed, I put in the Asus cd and let it install its drivers. But I have no network access because it cant get an IP address. I'm using the same router that works perfectly for all the other pc's.

Someone please slap me and tell me what I forgot because I really dont feel like disassembling this thing and mailing it back. 🙁
 
😱 Restarting now. If this works, feel free to ban me for stupidity. Man, has it really been that long since I reinstalled Windows?

yes to both. I tried giving it an ip manually (ipconfig /renew) but it times out.

'ipconfig /renew' is not giving it an IP manually. You must actually go and type an IP address into your network settings.

You might want to run a network analyzer (packet sniffer) to see exactly what's going on.

I went into the advanced tab of my NIC and entered a value for "Network Address" but it doesnt appear to be the usual xxx.xxx.xxx.xxx format. Is this the correct method to manually enter a network address?
 
1. Try a different network cable.

2. Try an add-on PCI NIC. It's possible your onboard LAN has gotten flaky for some reason. No problems show up in device manager?

3. What OS are you running?

1. I tried the cable connected to the pc I'm using now.

2. It shows up fine in device manager. I think an add-on NIC will work fine but I'm annoyed that the mobo NIC wont work. I'll pull a nic out of an older machine this afternoon and try it.

3. XP Home
 
yep, a flaky onboard NIC. Interestingly enough, I have seen situations where the onboard NIC driver gets corrupted somehow, and reacts in precisely the way you described. But upon a reformat and clean install of XP, and then the NIC driver, the NIC worked properly again.

I tried that this morning with no luck but I might try that one more time before I consider RMA'ing the mobo. I almost feel like using a NIC i have on hand instead of going through the hassle of returning it but according to the specs this mobo has a gigabit NIC and I have none of those (but i'd have to go buy one for another pc on my network before gigabit would do anything for me).
 
ping 127.0.0.1 works fine. I manually gave the NIC an IP address and now it shows up on the router's "attached devices" screen. But there is still no network access. Anyone seen this before?
