'''AC1900 Dual-Band Smart Wi-Fi Wireless Router '''
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
- "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).
- 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
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
- 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)
Forum / news aggregator posts
- Update on Linksys WRT1900AC support on the OpenWrt Forums
- On the DD-WRT forums
- references this PCWorld article stating the device uses a Marvell chipset
- On the SmallNetBuilder Forums
- /r/linux thread on the first released OpenWrt patchset
- Known Reboot issues
- Announcement video on YouTube (1080p quality available)
- 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)
