As title suggests, my Pi with duplex hat won't automatically connect to the Wifi (WPA2 AES) unless I disconnect the USB adapter and reconnect it. The expected procedure is:

step 1: boot up pi-star;

step 2: auto-connect to wifi;

step 3: it connects.

In reality, the procedure is this:

step 1: boot up pi-star;

step 2: unplug USB Wifi adapter;

step 3: re-plug USB Wifi adapter

step 4: it connects

Once connected, it works well. I wonder if anyone else has had this problem, and if there's a way to fix it.

Have you tried different adapters? Same behavior for each?

I tried another adapter in the end, it seems to work OK for now.

Just a guess on my part, but your prior adapter may have been failing the way it did because of undervoltage conditions.
