WRT3200 5ghz Wifi goes down with 0 devices connected

Running version 19.07.2 and if I have 2 devices connected to the 5ghz wifi band. If both devices are shut down or if they are out of range leaving the 5ghz band unused. If I try and use the 5ghz band again I cannot unless I restart the entire device. I believe this was an issue at the early start of the WRT1900 series routers as well. Please advise how this should be fixed? Last I heard there was a driver update for the wireless card.
