Hi everyone, I'm writing from Italy. I have a TP-Link Aginet XB432v router, and recently, for some unknown reason, my smart bulb (which had been connected without issues for a year and a half) suddenly decided to drop its connection. I factory reset it, but my network just can't find it anymore. Strangely, it switches out of pairing mode (fast flashing) and goes solid, but the app still doesn't pick it up.
I ended up buying a new Imou smart bulb from a local shop. Even though the app actually detects this one, the setup keeps failing. The only way I can get it to connect is by setting up a mobile hotspot and forcing the 2.4 GHz band, but obviously, I lose all my smart home automations doing it this way.
I've been reading up on it, and it seems like the issue might be either band steering or the WPA3 / WPA2-PSK security protocols. I tried setting up a guest network, but if I disable band steering, use the same SSID, and lock it to 2.4 GHz, it forces those exact same changes onto my main network too.
I'm at a bit of a loss here—does anyone know how to fix this? Any help would be massively appreciated. Thanks a lot!
P.S. My ISP is WindTre (an Italian provider), which means my router's firmware is locked down by them, so I don't have access to all the advanced settings.
