(a) When unconnected:

Connected to my iPhone hotspot:

I see that, thank you. And another interesting thing is when I use “ifconfig wlan0 scan”, all the networks’ rate showing are 54M, is that another bug?

(b) What’s more, I cannot select “network options” and scan Wi-Fis in it.
Has anyone reported this bug? Do I need to do that?

(c)&(d) That’s pretty annoying, can I suppress these messages?

(e) A new bug? If the SSID contains Unicode characters, it seems I’m unable to connect as well. Ifconfig wlan0 scan only outputs an incomplete hexadecimal value of it.
