I am facing problem with my Windows network adapter. It detects all the available networks but it shows "Limited Access" for the network I wish to connect. On diagnostics it gives "The wireless network adapter is experiencing problems" and on further diagnostics it says "There might be a problem with the driver for the Wireless Connection Adapter". What to do?

Based on another answer I participated in, you might check your energy management options for the adapter. Windows (in its infinitely helpful wisdom!) might be disabling power to the adapter in some conditions. I remember there being an option worded like "allow windows to disable this device to save power" ... although that's from an XP system, Win7 should have something similar.
Most likely under 'Properties' of the adapter, then 'options' or such.
You know the adaptor is fine because it works in another operating system. You also know the network is correctly configured on the modem/router end because you can connect okay via Ethernet. That means we are either looking at a physical problem or a configuration issue.
Physical problems with wireless cards are generally caused by poor reception. To check this try booting back into Linux and checking the strength of your wireless network by using a tool such as Stumbler (http://tools.meraki.com/stumbler). You would be surprised how often nuances in the driver code mean signal strength is sufficient in one operating system but not another.
As for configuration there are a number of things you can look at.
Start by going into Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings and check the wireless adaptor is enabled. This is a basic one and not likely to be the cause of your problem as the connection utility is detecting the network settings.
Failing that go into Device Manager. Find your wireless network card under "Network adaptors". Right click and go properties. There are quite a few things to check.
In the general tab check the Device Status says "This device is working properly."
In the advanced tab check the properties are correctly set. Most of these are tech jargon so be sure to use jargon. In particular look at power management properties and turn these off.
Related to that last point untick all power management in the power management tab.
Finally we come to the driver tab. In my experience this is where your problem will lie. The Intel Celerino WiFi N1030 for installing with the wrong drivers. I know you said you got the most up-to-date drivers but try getting them from Dell not Intel.
If none of the above works return to the list of network adaptors in device manager and check for duplicate devices. Be sure to enable showing hidden devices. In particular you are looking out for duplicate: Microsoft ISATAP Adapters, or Microsoft Virtual WiFI Miniport Adapters, or Wan Miniport Drivers.
One final pointer, I have experienced it in the past where this is caused by overheating not anything to do with drivers. If this becomes an intermittent problem try monitoring the temperature of your computer.
This is a comprehensive so if you follow my steps you will fix your problem. Good luck buddy!

The problem happens to me all the time. I think it is one of the reasons to prefer linux over windows since these problems only accure in windows.
You want it or not you have and will have these kind of problems in the future. Thats the downside of windows.
This is what I do every time this happens to me:
Go to
Control Panel
->
Network and Internet
->
Network and Sharing Center
->
Change adapter settings
You see one or more wireless adapters, disable the first one which is named your real wifi card (ie intel) By right clicking on it and selecting
Disable
:Then after some seconds, again right click and select
Enable
.The problem should have gone now.
