I am unable to connect to my well-established WPA2PSK/AES wireless network because the password has a comma in it. I have verified that this is the culprit by creating a new wireless network and varying the password to include or remove the comma. I get consistent results: including the comma prevents the Omega2+ from connecting, but it works properly if I remove the comma or replace it with a simple alphanumeric character.
I'm using firmware version 0.1.6 b138 (up-to-date at this time).
In resolving this problem it may be worth verifying that all characters permitted by the Wifi specs are supported properly. I haven't tested any other non-alphanumeric characters except space and exclamation point. Both of those work as expected.
