Windows 7: Connection doesn't have a valid IP configuration.

Connection doesn't have a valid IP configuration.

Hey guys, little problem here. I just bought my wife a new laptop with Windows 7 on it. When I first got a hold of it, I proceeded to remove all the HP bloatware that was installed. I went to Add/Remove programs and uninstalled everything that had HP beside it.

Next, I tried to have the laptop connect to my wireless router (DLINK DI-524). It found my network, but only with limited connectivity. I ran the troubleshooter and it reported back that the wireless network connection doesn't have a valid IP configuration.

I then connected my internet cable directly to the laptop and I get the same message, except it says "local area connection .......".

I have tried uninstalling/reinstalling the network adapter, but to no avail. Any other suggestions from you guys? I know it's probably something glaringly obvious that I am just overlooking...

Quick facts
1. Internet works on my desktop.
2. Desktop has Windows Vista.
3. Internet will not connect on laptop directly or through router.
4. I have reset/rolled back/reinstalled/uninstalled everything network card related.
5. At first I uninstalled all HP bloatware on laptop

You could always try using a static IP address

Firstly Open "control panel" click on "network and sharing center"

Click on "local area connection (1)" then follow the image clicking through to (5)
Once at 5 enter your IP address .... this will depend on what address your network is running on (I'm hoping that you know this already) I've given an example. If you router is set to eg 192.168.0.1 then you will need to enter this into the "default gateway" and "preferred DNS (6)" (I've marked the last number with an "X" as this could differ) When you enter your IP address just change the last number to anything between say 10 - 20 eg. 192.168.0.10

Do the same for your Wireless connection but change the 10 to maybe 11 ( eg 192.168.0.11)

On you desktop computer "the 1 that works " open up a command prompt (click "start" "run" type "cmd")
In the window that comes up type ipconfig /all

Post back the results it will look something like this

Hi infiniteuse, you have an issue with DNS, there isn't any from that detail.

If you know the DNS you cna append them into your DNS tab of tcp/ip4 setting.

Ok, well I tried what you suggested and it did not work. I attached a screen of what my laptop looks like when I did it to make sure I did it right.

Note: The screen is actually from my desktop because I could not get [prt sc] to work on the laptop! I just copied what I did exactly on the laptop.

Ok, I noticed that I did not follow your instructions too well.

This is what it looks like now, but still isn't working. When I troubleshoot now, it tells me that Windows can not detect any problems, yet I still have the yellow ! triangle and cannot access the internet.

Oh, sorry for the confusion. The pictures I am attaching are from my working machine because for some reason I cannot use the [prt sc] button and paste into paint like I normally do on the Windows 7 laptop, so I am showing you what I am doing by mimicking what I am doing on the laptop through my desktop. Man, I think I just confused myself also...

From working machine.

Try this pal
The two machines must have the same subnet mask, gateway and dns only the ip address should differ (last three digits)
