I suspect this has a failure with client test, restarting rollup and will report back

Client passed in the rollup without this PR, I'll start CI here to get results here as well

I still get RSSI result as 0

Using this example:
https://os.mbed.com/teams/mbed-os-examples/code/mbed-os-example-wifi/

Terminal output:

Done

Not sure why the Mbed-os version is showing 5.13.1 my Revision History indicates 5.14.0-1

[AnttiKauppila]

@star297 Example was not updated for 5.14. Should work now
