"WAVE RUNNER 11AX M[AIN BOARD]", "PWB:ARCT05381 RevB", and

"30-NOV-2017" are silkscreened on the board in the FCC photos.

The tagline comes from this list of UL Certified products from Arris

The 2.4GHz radio doubles as a receive-only 1x1:1 5GHz radio

A variant called W30 is mentioned with the C2PC request documents at the FCC. The difference is the W31 has a matte black colored bottom while the W30's bottom is silver.
