Dell Venue 7140 WiFi workaround

This tablet's WiFi needs a reset every now and then, I use a simple batch file to do it:

devcon disable "PCI\VEN_8086&DEV_095A&SUBSYS_55108086&REV_3B"
devcon enable "PCI\VEN_8086&DEV_095A&SUBSYS_55108086&REV_3B"

You need to create a batch file, say, rstwf.bat, in a folder and copy and paste above two lines into it. You also need to find the devcon.exe file on the net and put it into the same folder. To use it, open a Command Prompt as administrator and type rstwf.bat, enter.
