What reviewers say about the Motorola B12
Only one whitelisted tester, Tom's Guide, covers the Motorola B12, and only as a design-first roundup pick (Best for simplicity), not a benchmarked review; no lab speed numbers were published for this model. It is praised for a uniquely compact, decor-friendly build, a 2.5 Gbps Ethernet port, the MotoSync app and a two-year warranty, but flagged for a single status LED and ISP setup friction.

Another thing that sets the B12 apart is Motorola's MotoSync app, which makes it easy to set up and manage your new modem from your smartphone.

Source: en-us.support.motorola.com (verified 2026-07-11) · corroborated by walmart.com. The official Motorola B12 data sheet (source) confirms the exact model — "B12 ... DOCSIS 3.1 + 2.5 Gbps Ethernet" — and states DOCSIS 3.1 with 32x8 DOCSIS 3.0 fallback, downstream "Up to 2.5 Gbps", upstream "Up to 766 Mbps", 2 OFDM downstream / two OFDMA upstream channels, one 100/1000/2500 Ethernet LAN port, and a configurable 5-85 MHz upstream diplexer (mid-split). Walmart.com (corroboration) confirms the same model and specs (DOCSIS 3.1, "32x8 DOCSIS 3.0", 2.5 Gbps port, 2500 Mbps max) and lists the price verbatim as "Current price is USD $130.95". A separately fetched Amazon listing (Model Number B12, Mfr Part Number B12) additionally states the modem "Applies Active Queue Management (AQM)", supporting that boolean; maxUploadGbps is null because only a Mbps figure (766 Mbps) is stated and no verbatim Gbps value exists, and weightGrams is null as no weight appears on any fetched page.
