After updating from Android 10 to 11 the “Wi-Fi frequency band” setting in the Wi-Fi preferences disapeared.
Appearently the FP3+ sometimes has a problem / bug when connecting with 5 Ghz to certain routers. I was affected with this problem and it was completely solved by forcing my Wi-Fi to only use 2.4 Ghz.
Does anyone know where this setting is gone to, or why it was removed? Is there an alternative? Right now my FP3+ is close to unusable at home…
