AC1900 Dual-Band Smart Wi-Fi Wireless Router

Product page | • Support page(Template link outdated)

Wi-Fi Certified (alt.) (as of 12/12/2013)

This device could possibly be somewhat (or really) similar to Marvell's RD-88W-AP-8864-DR1
ref. design (certified on 12/28) notes each radio as using 3 spatial streams, OS as Linux 3.2.40

FCC info[edit]

  • "48SAM103.SGF" would appear to be silkscreened on the board in the FCC photos.
"48.SAM102.SGC" and "2013.08.14" is silkscreened on the wireless module shown.
The 802.11 ASICs markings are not easily discernible.
The 2.4GHz PAMs in use look to be SE2623Ls.
The 5GHz PAMs in use seem to be SKY85402s.
The style of the module is similar to that of the module used in the Google Fiber Network Box (GFRG110) (also using a Marvell based board).

Presumed specifications[edit]

  • WI: Each radio is presumed to be 4x4:3 and provided by a 88W8864 IC
    • Other ICs potentially have been used (mostly with regards to the 2.4 GHz radio, but unannounced silicon / P/Ns possibly for both),
but 88W8764 is older silicon and may not support QAM256 (which is presumably how the 600 Mbps data rate is arising for the 2.4 GHz band).
The product brief also explicitly states the max. PHY rate as 450 Mbps..
  • USB + other external expansion: 1x USB 3.0 port and 1x USB 2.0 / eSATA combo port

Additional external links[edit]



Mainline OpenWrt support was noted as targeted for support by Belkin-Linksys before this device's release
See this post (Update on Linksys WRT1900AC support) on the OpenWrt Forums for more details.

Reg. third party FW support[edit]

The wireless driver was submitted as a blob (ap8x.ko)..
the board (Mamba) is noted as using an MV78230 (ARMADA XP) CPU and Renesas uPD720202 USB3 controller (an EtronTech controller is shown in the FCC photos)

Forum / news aggregator posts[edit]


The shown board seems to be manufactured by Wistron NeWeb ("48SAM103.SGB" / something like that appears to be silkscreened on it)
Linksys's previous Broadcom based gear manuf. by WNC had a board P/N starting with 48SAB, seeming to indicate that it is Marvell powered (MTK may still be R)
The Wi-Fi radios would appear to be modular (Mini PCIe)
