When it gets stuck at connecting you need to turn the connection back to automatic. Reboot the modem and router (i think you only need to do the modem, haven't rebooted in a while but do both just in case). When the "Connecting..." starts back up wait about 10-30seconds (make sure it's before the first failure) and switch to manual config and put r.ispsn back in and save the setting.
Tech support didn't help at all and I had dig on my own on how to even get the zing to work with it. i posted this back on howard a year ago. I had my boss buy a mofi and it connects without any tweaking.
It works for my older surfsoho so it may work for the newer one too.
