Omega2: can't connect to wifi after setup. How to debug?

Ted Timmons

Omega2+. I can set it up in the web or cmdline, but after it reboots, it still isn't on my wifi network. (I've checked the dhcp list and used nmap to look for port 22). Here's some of the details I've found while looking around. What's next? I'm using the breadboard dock, I assume this dock doesn't provide serial output, I don't see it on my osx/macos USB list (system_profiler SPUSBDataType).

   Ω-ware: 0.1.5 b130

Nothing? I'd like to be able to use all my Onion hardware.

Does you SSID by chance have a hyphen - in the name or an overly long name? Those 2 things have been discussed here recently to having it not connect to wifi.

Also, what is you network.config 'uci show network' listed as? Does your wifi support DHCP or fixed IP's? If it's not setup for DHCP it won't get an IP address even though it see's it. Lots to try and test but not sure what you've already tried.

@Ted-Timmons

According to your uci show

wireless.@wifi-iface[0].ApCliEnable='0'
You simply disabled Omega's Wifi client.

What about Omega's Wifi AP?
wireless.ra0.disabled='1' means the AP (more exactly the whole Wifi system) is disabled
wireless.ra0.disabled='0' means the AP is enabled

You can debug and / or correct this with a serial terminal (for example via a 3.3V logic level serial to USB adapter).

@Ted-Timmons
A Factory Restore should bring back the default AP
~~if your Omega's Wifi is misconfigured only~~
if only the Wifi is misconfigured. ( Maybe it's much clearer.:thinking: )

hyphen, yes. Is there a fix/workaround? (besides renaming my network)

I did a factory restore, disabled=0, at least now. Presumably it's been that way because I can't connect to it over serial/USB anyhow.

As I said, I did a factory restore, then did a setup to a network without a hyphen. I notice the wireless.@wifi-iface[0].Ap* entries are added by wifisetup; it also creates the wireless.@wifi-config[0]* entries. Those don't connect, though- I've tried rebooting and checking both ifconfig and route to see.

Finally, I tried adding device ra0 to the wifi-config, it didn't make a difference.

Next step: changed wifi-iface.ApCliEnable to 1. No change.

set the debug flag in wifisetup, reran. Output:

Current Count: 1
Number of configured nets: 1

wwan network is set up... false,
ran out of configured networks... no station available
Wifi manager finished

Created a network with a hidden SSID, no auth. Manually configured it in config/wireless. No dice. What's notable is zero packets are received with any of these failures:

My router is on channel 1, fwiw.
