VC3 Wifi Disconnecting Issues
Hello all, I am struggling with wifi disconnecting on my V Core 3. At random, mid print, once every day or three, the pi4b will drop from my wifi never to return. It continues printing just fine, but I lose the ability to control and monitor it with mainsail.
Why I think it's disconnecting: I suddenly lose the ability to open ratos.local, and I cannot find it in my router's connected devices anymore.
The reason I am asking here is that I have multiple other printers, 2 Sovol SV08's with their proprietary pi knock-off, and 3 other modified klipperized printers running on their own raspberry pi 4b's, same as the RatRig except set up starting from stock raspberry os. None of my other printers have ever had this issue, so I am suspecting it is software related, perhaps some configuration choice made by Ratos that I am not aware of.
It is as if the pi never attempts to reconnect to wifi. It always has plenty fine signal, and could connect if it tried, but it just doesn't. It connects without issue every time it boots up, but I can't reboot it during a print.
The one thing I thought to check was the wifi low power mode, but
iwconfig wlan0 shows power off which I believe means it was never set to allow dropping into low power mode.
Does anyone have any ideas for further troubleshooting or how I can resolve this issue?
