I have a Rpi 3 b+ that was connected to a router that had a SSID for 2.4 and another for 5ghz, but I changed it and it has both bands on the same SSID, now the Rpi connects but with iwconfig I get that its connected to the 2.4 band.
How do I force the Rpi to connect to the 5Ghz band and only fall back to 2.4 when theres a problem?
Thanks
