Not exactly sure what fixed it, but after trying to connect again it gave me the option to skip, after spiking it connected to the Wi-Fi and downloaded & installed the firmware update. All working now.
@Christian-Toller in the omega2 /etc/config/wireless you are missing the > in '<router SSID' for both instances. not that it matters, i just noticed when reading. it's a good guide should i have the problem. it was either you or someone else that mentioned this issue before and as i result i tested my omega2 devices by unplugging my router they connect to and all 3 of them had no issue with reconnecting once the router was back up so i started to think it might be an issue with your specific router but did not know of the re-write of the file at the time so i'll have to go and check the files before & after the next time i test.
