I have a Samsung 4G LTE Extender that I can't seem to get past step 11d. I've seen other posts on the same topic but haven't seen any resolution. The error I get is "Not In-service MME Communication Failure". Has anyone gotten a resolution to this? I've tried the suggestions like adding the device to DMZ zone, opening up ports, changing MTU size...nothing works. Is this network extender just not supported anymore?
Thanks,
Craig
