[arm-allstar] RPi Zero 2 W wireless slow

[David McGough]

Hi Larry,

The proper WiFi driver is automatically selected.  If it's not there, WiFi 
doesn't work at all.

yes Ping was from wireless router to specific devices Pi3 was fine Pi 
Zero 2 W was not. Same wireless router to different devices sitting few 
feet apart ...rest of system all works fin only Pi Zero 2 W has the issue.

 From what David said they are different wireless chips on Pi Zero and 
actual Pi3's so may have got the wireless loaded driver wrong.

Thank for the reply
