Internet Air Replaced AT&T Rural Fixed Wireless: What to do with old router?

For Uverse based services the customer is to return the equipment to a UPS or FedEx shipping center along with account number. Receive a receipt with tracking number you should keep for 12 months. If ATT fails to receive the equipment within 3 weeks of canceling can be charged $150 for the gateway per the TOS.

I would expect Fixed Wireless equipment to be the same… packed and shipped at ATT expense once you delivery the product to the appropriate shipping facility.

Responsibility for and Return of Equipment. Upon termination of your Service for any reason, AT&T shall remain the owner of the Wi-Fi Gateway, and you must return the Wi-Fi Gateway, undamaged, within 21 calendar days to AT&T. If the Wi-Fi Gateway is not returned within 21 calendar days, or is returned damaged, you will be charged for the replacement value of the Wi-Fi Gateway.

Although the Outdoor Antenna and APS will constitute AT&T Equipment during the term of any Fixed Wireless Internet Service, you will be considered the owner of the Outdoor Antenna and APS for all other purposes and you will not need to return the Outdoor Antenna and APS to AT&T upon termination of your Fixed Wireless Internet Service. Upon termination of your Service for any reason, the Outdoor Antenna and APS will remain where installed at your location and you will be solely responsible for any and all future service, care, maintenance and removal of the Outdoor Antenna and APS. Service, care, maintenance and removal of the Outdoor Antenna and APS should be performed only by an experienced professional; you should not attempt to perform such activities yourself. AT&T shall have no ongoing duty, obligation, or responsibility to perform any service, care, or maintenance on the Outdoor Antenna and/or APS or to uninstall or remove the Outdoor Antenna and/or APS after termination of the Service. AT&T shall have no liability to you or any other person or entity related to or arising out of the Outdoor Antenna and/or APS. You agree to indemnify and hold AT&T and its subsidiaries, affiliates, officers, agents, licensors, employees, sub-contractors, and partners harmless from any claim or demand, made after termination of Service, arising out of or related to the Outdoor Antenna and/or APS, including, but not limited to, claims for personal injury, property damage, wear and tear, or equipment degradation.

OK, so just show up and tell them the account number? And just the router, not the antenna power supply?

Tell them your prior account number.

Sounds like you return the gateway (5268AC) and its power supply.

VERY IMPORTANT!!!!

ALWAYS get a printed receipt for the equipment including the serial number so that you have PROOF

you made the attempt to return the item to AT&T! Keep that receipt for at least one year!

I showed up at the UPS store on 1/22/2024 with the router, and they scanned the barcoded serial number of the router and were able to find the account based on that. So they are tied into AT&T's system somehow. If you know your account number, you can compare it to what they print out on the "AT&T Equipment Return Receipt."

They didn't ask for the antenna power supply and apparently had no means to track that.
