I feel your pain. Can't get firmware to update. Disabled the 5ghz on my ATT router. Still not able to update firmware. Bought a dedicated 2.4ghz router. Plugged it into an ethernet port. Able to see my 2.4ghz network. PB app said connected to 2.4ghz router, but when I login to router can't see the PB MAC address. PB support has been a waste of time. My firmware level is d60. PB support tells me that is your problem you need to be on d62. Waited for OTA (Over the Air) update that was promised by PB support. That never happened. Beyond frustrated.
