moto g 2014 can't connect to wireless office network. I'm not sure if this occurred before or after marsmallow upgrade. I was able to use the network w.out a problem for a while before this issue. I select the wireless network and int prompts for certificate. I don't have the name for certificate so can't do anything further. I tried loking for certs but the only option i have is to look on sd card and I don't see any there. My office IT staff won't help with personal devices, so I am on my own to solve this. I connect to my home and other wireless networks without a problem.
