Hello,
I have a similar issue to what this post was about, is there a resolution?
I'm running the latest firmware version:

11 packets transmitted, 0 packets received, 100% packet loss
So the driver does seem recoverable since I ran the unload_cc33xx.sh and then re-loaded using load_cc33xx.sh and I was able to set up the wlan station and connect again.
Any thoughts here would be appreciated!
