Solved: PC cant recieve IP adress from router

[TommiHelm]

Hey.

Here's some info:

- ABIT KN8 Ultra motherboard
- GeForce 6600GT
- Windows XP
- I am using the onboard Ethernet card.


Today I got a new fan for my GPU and a heatsink for my motherboard. After installing these I all of a sudden couldnt connect to my router any more. This has me abit puzzled.

My system consists of a normal router (modem) and a wireless router which funciton as a HUB/Switch at the moment. There are 2 other computers connected to this netwok (including this one Im typing at right now). One is a laptop which use wireless and this one uses a normal DSL cable. My computer (the troubled one) also use a cable. The other 2 computers have no trouble connecting to the router and getting a IP adress assigned.

What happenes on my computer is windows tries to get a IP adress, but cant recieve any and assign me one of their own bogus ones. Which means I cant connect to neither the router nor the internet.

Ive tried a line of things today:

- installed new drivers for the Ethernet card, no luck.
- tried a USB network card (cabled), same problem.
- tried a USB network card (wireless), same problem.
- tried another cable, and also the same cable in other places. Safe to say the cable is fine, so that's not where the problem lies.
- restarted router, reset router, pretty much reset whatever is to reset to no use.
- installed windows fresh *sigh* but still same problem.
- tried a static IP adress, the one I normally get assigned (192.168.1.33) but no use, still cant even ping my own router (192.168.1.1).


Now here's what I think might be the issues, but Im really lost now and just throwing around thoughts:

- If I go on my network cards properties (in device management) I get no "resource" tab. Most devices do. Im not sure what this is, but I think its got to do with IRQ and devices not clashing with one another? Anyways a mate of mine has a onboard ethernet card aswell and he's got this "resource tab" on his. Can this be something? Is there a issue with another device locking the network card out? How can I find out more about it?

- Like I said I installed some cooling on my GPU and MB today. Actually me and a mate did. None of us are very experienced with such things, so is it possible we might have broken something? A circuit or anything? I just find it strange that the only thing not working seem to be the ability to recieve packets. Everything else seem fine. The network properties even show the connection sending packets, just not recieving any. Im really really confused.

- Before I reinstalled windows I was checking the Event Viewer. It had a error message right after I turned on the computer again after the fiddling. It was from "server" and was about not beeing able to do something cause of another computer having the same name. I dont remeber it 100% now, but it hasnt appeared again after the reinstall either. Either way, none of the computers on the network share names, that Im 100% sure of. But is it possible the router or my windows have some corrupted files/settings? I find it hard to believe thats it since like I said I did a fresh install of windows. Total reformat and new install.


As you can probably tell Im rather frustrated now, Ive spent all day on this and gone nowhere :( I hope you got some suggestions, cause Im all out I guess I might just have to get a new MoBo.


Cheers.

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

I already stated rather clearly that my PC isnt recieving any IP adress from the router. I dont see how this will help at all but here it is (I cant copy anything from my computer to this cause tihs one dont have any floppy/USB pin option (to old), so I had to type it down on a paper and rewrite it):

Windows IP Config

There you go, hope it helps, but I really think you got all this information in my first post already.

Oh, and I've also done the whole "TCP/IP stack repair options for use with Windows XP with SP2." thing :

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log


With no luck :(

If you have no resource tab in Device Manager, that suggests there's something wrong with the NIC or the drivers. What do you see in Device Manager now? Are you sure you loaded the chipset drivers and the PROPER NIC drivers?

[TommiHelm]

In Device Manager I can see the Network Card/Adapter and go into its properties. Here I get the normal fanes: General, Advanced, Driver, Details, Power Management (but no "Resources" fane).

Also the General fane give me the "Device is working properly" message, which just has me even more confused.


Yes after resinstalling windows I have installed the very latest chipset and ethernet drivers. As I said I have even tried a USB Network card (and yes I got the latest drivers for that aswell) and I still get the same problem. I get no "resources" fane on that one either. I even tried disabling the LAN controller in BIOS and reinstalling the USB card, but still nothing.


The fact that this only appeared after me and my mate was fiddling inside with installing 2 new fans makes me thing it can only be a damage on the Motherboard.

So, if someone could just answer me this :

* Is it even possible to get a damage on the Motherboard that is THIS localized that it only affects such a small part? If it's possible that's probably the issue and I will just order a new MoBo, cause Im going crazy here :D

Cheers.

[TommiHelm]

Ok, I tried a PCI card as my last resort and low and behold it worked *CHEER*

Why though? Can I now be certain my Motherboard has a very local damage somewhere? Should I get a new one after all? Right now Im not sure I can be bothered, Im just happy to be back online :D

Id still like to hear if anyone know why a PCI card works while a USB based one or the onboard one dont? Wouldnt the PCI card use the same controller as the USB based one?

Cheers.

[johnwill]

Obviously, the on-board NIC (not USB BTW) has some sort of issue, either it's broken, disabled in the BIOS, or the drivers have a problem.

There's no reason to buy a new computer, since you have a perfectly good working solution.

[TommiHelm]

Thanks, I was sure the PCI card would just use the same controllers as the USB and OnBoard card did, so I didnt think about trying one since the USB one didnt work.

The world is a happy place again :D

Cheers.

I have a local area connection problem! The icon in the bottom right hand corner is saying summits unplugged?

Help, please!
