LAN Connection Issue - limited or no connectivity

Hi,

I have a broadband modem which is connected to a wireless Belkin pre-n router. I have my brothers PC & my own PC hard wired to the router by ethernet cable & i have a laptop that connects wirelessly.

This home network has been working fine for a few years BUT around a week ago i started to get a "limited or no connectivity" msg on boot up on my pc. I couldn't link to the network or internet.
I tried switching all the linked machines off and booting them up one by one (in this order: Modem-router-brothers PC-My PC) but this made no difference.
My brothers connection remains fine. He can use the internet. I can also connect wirelessly with my laptop. This issue only seems to be affecting my PC.
In order to get the connection to work on a one off occasion, i would have to boot up the PC (and have the "no connection" msg appear) then swicth off the PC, switch the power supply off completely from the plug & take out the ethernet cable. I would then switch on the power supply & boot up the PC. Once windows XP was fully booted, i then insert the ethernet cable & my connection is restored and i can use the internet. BUT when i switch the PC off again and reboot, the connection goes again.

I have tried to assign a static ip address (192.168.2.2 with subnet mask 255.255.0.0). This seemed to remove the error but my internet would not work.
Furthermore, when the connection messages would appear, when i tried to open the network adapter properties, the properties window would freeze & not respond at all.
And all along, my brothers PC connection & my wireless laptops connection seem to work fine.
MY windows XP is fully updated and has service pack 3 on it plus all of my drivers seem to be up to date. As mentioned, this network worked fine for several years and the error has occurred only last week on my PC only.
Any ideas how to fix this issue?

Regards, Shuja

Have you reinstalled the Lan card driver?

No, i haven't reinstalled the LAN card driver BUT it had been working fine previously & i've made no change to the system.
I can try to re-install the driver but i'm not sure this will help.

“BUT it had been working fine previously”

Doesn’t mean a thing the driver can get corrupted for no reason, a update of the OS or a Program, Antivirus, update etc

Update to the latest Lan driver and see if that fixes your problem

If not try a difference port on the router

So, does anyone have any idea why i keep losing connectivity when other PCs connected to the router work fine?

169 IP Address - Limited or no connectivity

With the cable plug into the Lan port the IP address is “Incorrect”

IP Address. . . : “169.254.149.150”

With the cable unplug from the Lan port the IP address is correct

IP Address. . . . . . . . . . . . : 192.168.2.4

As I said try a difference port on the router if that still not working take a read

Turns out it may well have been a damaged/corrupted network card.
I tried to uninstall the card driver & re-install, i tried a new ethernet cable, new port in the router but nothing worked.
As this network card was built-in to the motherboard, i decided to buy a new one for the PCI slot. This new card seems to have resolved the issue.

“This new card seems to have resolved the issue”

Glad to hear all working again

Don’t forget to tick the box and click Resolved
