WiFi & App Connection Problems
Smart device connectivity issues are the #1 complaint across all IoT products. The problem is almost never the device itself — it's the network setup. Dual-band routers that auto-switch between 2.4GHz and 5GHz cause the most headaches, since many smart devices only work on 2.4GHz. App pairing failures, devices going offline, and "device not found" errors usually trace back to the same handful of network configuration issues.
