Wireless Network Connection doesn't have valid IP configuration

[Warrenisit]

Hey, guys.  Got a problem connecting to the internet.  I searched the forums but didn't find the same question so here I am.

I have a brand new computer that has worked fine until I called Comcast and had them mess with the connection due to it being super slow.  When they were done and I was off the phone I couldn't connect at all and when I called Comcast back they said it was a computer problem not their problem so they couldn't help me.  They said this because my other computer is connected just fine to the internet. 

When I try to connect it either says "windows was unable to connect" or "Identifying.... no network access."  After I troubleshoot the problem it tells me  "Wireless Network Connection doesn't have valid IP configuration" but it's also said "Problem with wireless adapter or access point." 

I have restarted the computer a few times.  I have unplugged and restarted my router a few times and I'm still lost.  I'm typing this all on my other computer connected to the same router so I don't think it's the router.  Here's all the computer info (for the computer not connecting of course.)

Windows 7 Home Premium, 6.1.7601 Service Pack 1 Build 7601

HP Pavilion dv7 Notebook PC

8 GB of RAM

Using Avast as an antivirus.


I'm pretty positive this isn't virus or malware related.  I haven't had any signs or symptoms of malware/viruses and haven't been browsing any porn sites with this comp.  Thank you for all the help as always and if you need more info please let me know.

It just connected for a minute then disconnected all by itself.  It only disconnected after browsing for a minute.

"...valid IP configuration..." makes me think that it is something related to your router's DHCP server. Try assigning a static IP to your laptop and see what happens. What is the make and model of your router?
Also, are there any issues with a direct wired connection from the router to the laptop?

[Warrenisit]

Not sure how to assign a static IP but the make and model of the router is NetGear N300 Wireless Router WNR2000 v2 and yes, it does connect to the internet when directly connected to the router.

This is how to assign a static IP:

DHCP is not enabled with this computer- Fixed

Alright, I'm connected to the internet again and hopefully it doesn't cut out on me again shortly.  Was that all it took to fix or is there more to it?

[Transfusion]

That probably is all. If you wanna stress-test your connection to the internet you can go to http://www.speedtest.net

As I was typing a thank you reply my connection *censored* the bed again.     Any other thoughts on the problem?

[Warrenisit]

Now the connection came back all by itself.....

[Transfusion]

This is getting odd... if the connection keeps dropping again let us know and we'll have more suggestions...

[Warrenisit]

Yup, it just dropped again but before it drops I have full bars.

[Warrenisit]

Now it's back without me trouble shooting or anything but my other computer has kept a steady connection.

So now you have limited connectivity. At least we have a little progress.

Is your router upgraded to the latest firmware?
Does your PC WiFi card have the latest drivers?

my connection **** the bed again.

Could you avoid language of this type?

[Warrenisit]

Tried doing step by step what the link told me to but it's a bit over my head so I've been unable to complete it.  The computer continues gain and lose connection all on it's own.
