Wireless Card Issue

I have a 2 month old Dell Inspiron 14z with Windows 7. My Wifi Connection will drop out every 5-10 minutes and I have to reconnect to the network. In addition, everytime I wake my computer up from sleep mode, it will take 2-3 minutes to connect to wifi and I always have to try multiple times to connect to the network before it works. Sometimes when I try the troubleshoot issues, it says that my wireless card is not functioning properly.

  3. Click the + sign to expand the ‘Network Adapters’ entry.
  4. Right-click the wireless adapter and click ‘Properties’.
  5. Click on 'Power Management'.
  6. Uncheck 'Allow the computer to turn off this device to save power'.

If the issue still persists, update the BIOS:

Note: Please save any unsaved data as your system will restart automatically after updating the BIOS. Disconnect all the external peripherals like printer, camera, scanner, external hard drive, flash drive etc. Also, the battery should be charged 10% or above.

I have same problem on my Studio XPS where ONLY the downloading internet speed with a connection at 11MG (I tested same time on MACs = 11MG) changes continuously to lower than 3MG and often going close to zero and stall the applications.

Can you suggest what to do?
