i had the same issue. this could be a bug because the output of ifconfig wlan0 is this

...
        RX packets 32793  bytes 5096198 (4.8 MiB)
        RX errors 0  dropped 2  overruns 0  frame 0
        TX packets 39938  bytes 36256917 (34.5 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

and the regex for extracting this data is incorrect here is the proof and here is a way to correct this bug

@itshaadi thanks for doing the regex check. We transitioned to using ip rather than ifconfig in this commit and it appears we lost RX/TX stats in the process. @hjacas this is indeed a bug that we need to fix.

@billz I tried adding this exec( 'ip -s link show ' . RASPI_WIFI_CLIENT_INTERFACE, $return ); under exec( 'iwconfig ' . RASPI_WIFI_CLIENT_INTERFACE, $return );
I Just can't parse the correct result
this is the output for me
