Not really, unfortunately.

It seems to me that the current wifi kernel module is unable to correctly interpret one or more of these ASCII characters and since it's a closed source component, you cannot examine it to find out why.

You might want to log a ticket on the Onion helpdesk and provide them with these ASCII characters, together with a pointer to this thread and a request to troubleshoot the wifi module. Perhaps that way they can enhance the module with some new functionality or a bug fix, whatever may be necessary?

Apart from that, or perhaps changing your SSID's, I'm not really sure what else to suggest.

@Lazar-Demin
Thank you. That's what I need.

@cas
Thank you. I have it working now. When I isolate what the minimal parameter change is, I will post more information.
Cheers,
Dan

@dklinkman Could you please detail how you did this? =D

Updating...

This board worked (Omega is on for more than 1 hour and no problem), but using the both source together :S (There are two regulators)

@Valentin-Haenel
Thanks for putting up your findings!

We're working on tutorials regarding the wireless configuration. And we're also doing some work in terms of connecting to wifi networks. Stay tuned!
