[Pyro] Network test failing when run as part of 'wifi_matfunc/wifi_release' suite

Project Member Reported by aashuto...@chromium.org, Mar 23 2017 
Chrome OS Version: <From about:version: Platform 9202.56.0 >
Chrome OS Platform: <Pyro>
Network info: <>

Network test failing on pyro device (also seeing on couple of other devices) are failing with the following error
"AttributeError: 'network_WiFi_DisconnectClearsIP' object has no attribute '_wifi_context'"
Also with  "Unable to find /usr/sbin/iw" error, I see the module, when I login to the DUT and check manually. 

Sample Failure:

When, I run the test independently, It does not throw any error. This is the case for all of the test cases, I re-ran.

I have also seen this on other devices with R57 builds. This looks like  Infra/Autotest related. 

Will check and update, if it continues to be an issue on latest ToT

Summary: [Pyro] Network test failing when run as part of 'wifi_matfunc/wifi_release' suite (was: [Pyro] Network test failing when run as part of 'wifi_matfunc' suite)
I continue to see similar issues on Pyro  9202.66.0 - 57.0.2987.148 

Most of the test cases failed with following error
"ERROR: Unable to find /usr/sbin/iw"

Just re-running the failed test, does not throw any error.

I'm pretty sure this is a bug in the test or in the platform,
not in autotest.
