Guys. Need all the expert here for help.
After sign up to Unifi Air. I pair the sim with my own 4G modem. (Tenda 680v2) But as u all can see. It connected to the LTE and have 4bar signal and all. But I just can’t get into the internet. My place are just few Km away from the blue spot. I tried several method like set up APN, update modem firmware and factory reset but none of it works. Do you guys have any idea what other problem could be?
