AT&T 3G Sunset – Required Cellular Firmware Update for 110g

AT&T is turning off their 3G network on 2/22/22, which affects the Quectel modems on the 110g Airwall Gateway, and any AV3200g/u Airwall Gateways installed before Dec 12, 2021. If you are operating one of these Airwall Gateways using an AT&T cellular connection, you should install new cellular firmware on them before the AT&T shutoff date.

Warning: To avoid disruptions in your AT&T cellular service, you must update your cellular firmware on 110g Airwall Gateways before 2/22/22. If you don't, you will have to have an ethernet connection or perform on-site diagnostics for all impacted Airwall Gateways to restore reliable cell connectivity.
Attention: If you already updated Airwall Gateways that are using T-Mobile cellular – Install the latest (build 125) update to correct any issues.
