Connected to Router but no internet access

October 2, 2011 at 14:04:48
Specs: Windows XP
I am able to connect to my router, both wirelessly and hard-wired. However, I am unable to access the internet from my laptop through either connection. I get the "cannot find server or DNS Error" message. I am able to connect to the internet on another desktop through the same router and my wife's laptop is able to connect through a wireless connection to the same router. The laptop I am having the problems with did in fact connect to the internet a few days ago, but now nothing. It is an older laptop, an HP Pavilion ZD8000 running XP Pro. Anyone able to offer some insight I would greatly appreciate. Thanks.

As you can see, the "Autoconfiguration IP Address" (that's the ip of your computers wireless network card) is the same as the "Default Gateway" (that's the ip address of the router).

These addresses must be different.
While it's automatically configure by Windows, press WIN+R, type cmd and click ok.

In the upcoming back command prompt, type in ipconfig /release and press enter key.
After that, type in ipconfig /renew and press enter key.

Then again check, whether the ip address of your computer differes from the ip address of the default gateway, by using ipconfig /all.

Report back the result.

Ok the hard wired pc is ok and I bet it's working.

The laptop got no ip via DHCP from the router.
This is indicated by the ip address 169.254.x.x, in your case 169.254.139.184.

Try to reboot the laptop. This may help to reconnect to the router correctly.

I restarted, but still have the default gateway address absent. So I still have the "limited or no connectivity" message.

Not just the default gateway but also you get no valid ip address of the router.
The ip address must be in range of 192.168.1.2 - 192.168.1.254.

Maybe the laptop has no permission, to authenticate to the router.
This can cause by using a wrong encryption type and encryption key, or maybe there is MAC address filtering configured in the router, and the laptops MAC address (00:90:4B:EF:71:9A) is not in the list of permitted addresses.
