Actiontec C3000A

Overview
According to a Declaration of Similarity document submitted to the FCC,
 * "Models C3000A and T3260 are identical in hardware design.

The purpose for 2 model numbers is to clarify specifically for one large
 * customer versus generic consumer products."

Per marketplace (eBay) labels, CenturyLink branded variants of the C3000A seem to use CenturyLinkXXXX and CenturyLinkXXXX-5G SSIDS.

Chip IDs are not legible in the FCC internal photos so they are just a guess.
