Just received a brand new Rpi 4B, installed the latest Rasbian Desktop. Did all the usual updates/upgrades
Rpi would not connect to my wireless network. My router is a Billion BiPac 5200G R4 and the wifi is operating on 2.4Ghz.
After much head scratching, realised that the Rpi may need a 5Ghz wireless connection, so I borrowed a BT Hub 4 which has this capability.
The Rpi connects with the wireless of the BTHub 4 and is assigned an ip address and works ok.
Surely it must be possible for the Rpi 4B to work with 2.4Ghz wireless routers such as my Billion router. I have previous versions of the Rpi and they all work with my Billion router.
Could someone explain what might be going on and have i missed something about configuring the Rpi 4B to use 2.4Ghz.
