If you or anyone else reading this uses Quantum Fiber (QF) as their Internet providerr Internet provider, QF recently ended their licensing agreement with Plume. The QF tech mentioned that Plume provided the mesh network software for the QF pods. This explains the low bandwidth performance and inability to configure some of my QF pods via the QF app.
As others have noted, they use Eero for their mesh network which I'll also do.
Others here have answered your 3 questions but I wanted QF subscribers to know they likely no longer have a mesh network via the QF pods. Wouldn't it be nice for QF to inform their subscribers?
