os.systemis a very old choice and not really recommended.

Instead you should consider subprocess.call() or subprocess.Popen().

Here is how to use them:

If you don't care about the output, then:

import subprocess
...
subprocess.call('netsh interface ipv4 set interface ""Wireless Network" metric=1', shell=True)

If you do care about the output, then:

netshcmd=subprocess.Popen('netsh interface ipv4 set interface ""Wireless Network" metric=1', shell=True, stderr=subprocess.PIPE, stdout=subprocess.PIPE )
output, errors =  netshcmd.communicate()
if errors: 
   print "WARNING: ", errors
 else:
   print "SUCCESS ", output
