i have checked the the adapter but there is no antena diversity, and i am having the same problem.

Earlier it was Mcafe , even tried uninstalling that , still same issue. now i have installed microsoft security essentials .

The problem is if i am sitting near to the router it is functioning as other laptops. But if i am trying from other room , it is giving problem, whereas in other room my other laptops are running fine.

Deepsas,

What virus program are you using?

Rick

yes, i installed Notebook system software and the chipset drivers first then i installed rest.

As i told i am facing problem if i am trying from other room, where as other laptops are doing good from other room.

Deepsas,

Did you use the McAfee Removal Tool? You can still run it.

This says it for printers, but gets you to the firewall settings. Allow Printer past Microsoft Essentials See it there is something blocking it there.

Is your system under warranty?

Rick

Deepsas,

When you reinstalled the operating system, did you install the Desktop/Notebook system software and the chipset drivers first? If not, the rest of the drivers will fail to install. How to Download and Install Drivers in the Correct Order

Start with the Desktop/Notebook system software and the chipset drivers and follow the list.

Hi Rick, i just brought this laptopn one week before.

I completely removed the factory default windows 7 and installed windows 7 ultimate.

Even though the problem is there, i think the wifi adopter dell using in this laptop is not good enough to catch the signal.

Deepsas,

Try channel 11 in your wireless router?

I would contact Dell Tech Support and see if they can fix this.

Let me know what happens.

Rick

my wireless router is already running in channel 11...

exactly same problem with the same model!

Thanks Rick for your help, finger crossed.

Deepsas,

Keep me posted. I'd like to know what they did to solve this. I have friends looking into this.
