Linksys WRT1900AC v1
AC1900 Dual-Band Smart Wi-Fi Wireless Router - Mamba
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.
While released without any real third-party firmware support, the WRT1900AC (and subsequent Marvell variants) are fairly well supported now that mwlwifi has been integrated into OpenWrt/LEDE, though inclusion into the mainline Linux kernel is still pending.
"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).
Reg. third party FW support
- wrt1900ac/opensource repo on GitHub
- Belkin's first patchset for the WRT1900AC submitted to the OpenWrt-Devel ML
- 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)
