This is difficult to do with koreader at present.
I have discovered that to view networks you long press on WiFi connection.
This appears to be the only way to refresh the available networks. Frequently the network is not showing (eg when I enable a hotspot on my phone)
The user then needs to long press again and this seems to turn off WiFi. Long pressing again then turns it back on and then gives the available networks list.
Suggestion: add a refresh available network button to the network list screen.
