I've observed this too but after a few scans, not right away.

Interesting, thanks for the input @reconbot!

@kteza1 I have confirmed that running the command we use to get a scan of wifi networks (ubus call iwinfo scan '{"device":"wlan0"}') only works the first time on OpenWRT. Do you have any idea why that is or an alternative command we can use?

[johnnyman727]

I haven't confirmed why the command we are currently using only returns data once but I have confirmed another option:
iwinfo wlan0 scan

We will just need to change how we parse and display the JSON data after switching to this new command.

Gah this is frustrating. My Tessel, with the ap turned off and station mode turned off, will reliably return results with the old method of requesting networks. My Tessel also seems unable to connect to networks that it used too but I'm not confident that is related.
