Debugging Ubiquiti's 5G Backup on AT&T
Read OriginalThis article details a user's experience debugging the Ubiquiti UniFi 5G Backup device, a 5G RedCap-enabled modem, when used with an AT&T Business AIA plan. The user initially assumed AT&T business plans would support 5G RedCap, but encountered problems: the device got stuck in an update loop requiring TFTP recovery, and the SIM only connected via 4G LTE, yielding speeds of 30 Mbps down/12 Mbps up. AT&T's rep couldn't add the IMEI due to eligibility restrictions. The article includes debugging steps via SSH and the UI debug console, providing practical insights for similar setups.
