@s3v3n7w0, I’d had issues with my wifi as well but changed from a generic eBay wifi adapter (edup brand, RT5370 chipset) that has known issues with the Raspberry Pi to a TP-Link TL-WN725N & no further wi-fi connectivity issues. However, my scheduling issues persist and appear to be worse, with no schedules running automatically at all now. The OpenSprinkler process is running fine via its init.d script, so the problem I’m experiencing must be internal to the OS code.
