[Feature request] Show signal strength and speed of currently connected network

[pm4rcin]

Hi, in Port Authority you can see on main screen RSSI and speed of currently connected Wi-Fi network. Port Authority has that It would be great to add that probably on main screen under MAC address.

If the underlying framework or library can provide these details then I think we can at least add signal strength. But I still couldn't find a way to measure internet speed. I know mLab is there but has less resources.
