One of the better ISP-issued gateways. Manufactured by Humax in South Korea - no Chinese supply chain. AT&T provides regular firmware updates. Main limitation is reduced user control.
- Limited admin configuration: AT&T locks many settings. You cannot configure advanced firewall rules, custom DNS, or granular device policies.
- ISP remote access: Standard for all ISP gateways: AT&T can remotely access and modify this device.
- Historical gateway authentication bypass: An auth bypass was found in related AT&T gateway infrastructure in 2022. The BGW320 was not directly affected and AT&T patched quickly.
