[Transformer TF300T General] realaxed:
I am also having the same wifi issues people have reported here. I have a TF300 without 3G. Below are my journal logs in case it helps.

Can others with the wifi issue please post their journal logs here? A few days ago I fixed an error that is not appearing in the logs below. Apparently there is a folder that needs to be created.

The command to show the logs in terminal is: # journalctl -f (you have to be root)

@cb22: let me know if there is anything else I can send that would help.
