   Weird Wifi problem Pi Zero W   
   25 Aug 24 11:07:09   
   
   From: none@invalid.com   
      
   I have a Pi Zero W with a weird Wifi issue.   
      
   The Pi runs an SSH gateway and is powered from a USB port on the router.   
   It's been running faultlessly for about 2years now with a few tweaks to   
   the standard setup to mount regularly written to files on a ramdisk to   
   preserve the SDcard. The system reboots every 24hrs as a simple way of   
   stopping the ramdisk  filling up.   
      
   After a new router was installed, this Pi has issues connecting to Wifi.   
      
   Power it up and there's a 75% chance it will connect. If it doesn't   
   removing and reapplying power makes it likely to connect. If you reboot   
   it from the command line it fails to connect most times.   
      
   I have a spare Pi Zero W and swapped the SDcard into the spare. Connects   
   every time on reboot or on power-cycle. I place another SDcard in the   
   intermittent one and the same Wifi connection problem exists. One card   
   is Debian 12 with NetworkManager and one is Debian 11 with old style   
   networking setup.   
      
   The fault moves with the Pi and doesn't seem to be software dependent.   
   Using Debian 12 and checking with a USB Ethernet connection the Wifi   
   fails with "could not activate connection: Activation failed: secrets   
   were required but not provided" even though the password is set and has   
   connected. I've checked there's no dust/dirt or other contamination on   
   the PCB. I've powered it from several different USB ports (desktop,   
   router, phone charger).  The rest of the Pi seems to work fine when the   
   Ethernet connection is in use. Or when it was in an original Pi Model A   
   with a USB Wifi dongle, it boots and the Wifi connects. The software   
   image appears OK. It's just this Pi Zero W with iffy Wifi.   
      
   Has anyone seen anything like this? Most annoying. Any ideas?
