Ok *27 does not work on the OBi1032 so I am guessing the same issue exists in the OBi1022 firmware.
I factory reset my OBi1032, waited for it to reboot and then plugged in a OBiWIFI adaptor. Lifted handset and dialled *27 and nothing really happens. No new networks detected on any of my devices.
What I had to do is this... Using the phones keypad, navigate to Settings and press tick, scroll down to WiFi and press tick, with Enabled highlighted press tick to enable it, scroll down and highlight OBiWiFi Setup Mode and press tick again to enable it.
After a few seconds I now get a new WiFi network notification on my ipad called OBiWIFI_MYOBINUMBER and I can connect to it. Next I enter
http://192.168.10.1/wifi in my browsers URL which brings up the OBiWiFi Set-Up page.
I am able to complete the setup process.
