|    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?              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
