When I scan for hardware it says no new hardware found. If i restart after shutting down for few minutes it comes back. IS IT Coz of heating problem?
Please check whether your notebook Wireless Adapter is detected in the Notebook. To check this Click start and in the start search box type Device Manager and press enter. This will open Device Manager. Then Click on + sign next to network adapters and please check whether the wireless adapter is listed.( Broadcom or Intel Wireless Lan ) . If it is not listed then you need to install BIOS update for your notebook. After installing BIOS update it should resolve the issue. However, if the issue persists. I am afraid that you need to get your notebook repair.

Most likely the wireless adapter is going to sleep, go to device manager, then network adapters then the wireless adapter and right click on it and choose properties, then power options and uncheck allow this device to turn off to save power or similiar, To get to device manager right click on computer then properties then hardware then device manager, in win 8 its just properties then device manager win 7 also I believe
Most of the laptops those are the common issues Wireless are not working, what i suggest is try to renistall the Driver for the wireless card then check it in the Device Manager, if it doesn't show in Device Manager the wireless card could be faulty.
How to check Device manager.
Start->Control Panel->Device Manager
Inside Device Manager look for Network Adapter and check if your wireless card is detected.
If your device manager indicates a good network adapter, wireless and/or Ethernet, go to the Dell website, select support, drivers and download, and enter your service tag number. It will direct you to all the drivers you need to get you computer operational again.
If the device manager indicates missing network adapter drivers, you will need a flash drive, a computer that can connect to the Internet, and transfer the network adapter driver to this computer.
Uninstall the device from the device manager and in the device manager do this operation "Scan for hardware changes" , then u can find the wireless network adapter with no drivers installed. Then install the wireless device drivers , Ur Problem will be solved.
check in device manager to see if its enabled and have drivers installed.some wifi are installed without a wireless manager and connect to first available(strongest)network.
go into control panel ,administrative tools,sevices and scroll down to wireless zero config and start.
then when you click on wireless icon you will have choices of connections(AP'S)(access points)
Try going into the Device Manager and making sure the Wireless Adapter is enabled. Click Start > Control Panel > System. Click the Hardware tab then click the Device Manager button. Now click the Plus [+] next to Network adapters then double-click the wireless adapter which is probably the Intel(R) PRO/Wireless 2915ABG Network Connection which will open the Properties dialog. Ensure the Device status reads, "This device is working properly" and Device usage shows "Use this device (enable)." If either the Device status or Device usage shows anything other than what is shown above, first try to change the Device usage, which should change the Device status. Now try again to use your wireless adapter. You might need to press Fn + F5 to turn the device on.
It's possible that the driver for your wireless adapter is already installed. Check under Device Manager > Network Adapters if there is anything pertaining to your wireless adapter. Make sure that your wireless adapter (under Device manager > Network adapters) does not have any red X or yellow question mark.
Red X indicated that it's disabled , while yellow question mark will suggest that you need to update the driver. If your wireless adapter is working properly under Device Manager > Network adapters then you will need to configure it's utility for wireless connection.
If you are running windows XP, look for the wireless icon in the lower right side of your task bar and use it to connect to your preferred network.
