Overview

"EWW516-A1-BL REV:025(XC)" is silkscreened on the board in the FCC photos.

OEM: CyberTAN EWW516

Note: A Class II Permissive Change on September 11, 2018 to Q87-EA8300 which was originally

for the EA8300/EA8250 added two new models (MR8300 and MR8250) which are marketed using

"Mesh" terminology. Both new models have a "new LED design" and both support 256QAM.

The different names are used for marketing purposes.

Wi-Fi Certified : WFA79677 (as of 10/12/2018)

ipq40xx: Add support for Linksys MR8300 (Dallas) The Linksys MR8300 is based on QCA4019 and QCA9888 and provides three, independent radios. NAND provides two, alternate kernel/firmware images with fail-over provided by the OEM U-Boot. Hardware Highlights: SoC: IPQ4019 at 717 MHz (4 CPUs) RAM: 512MB RAM SoC: Qualcomm IPQ4019 at 717 MHz (4 CPUs) RAM: 512M DDR3 FLASH: 256 MB NAND (Winbond W29N02GV, 8-bit parallel) ETH: Qualcomm QCA8075 (4x GigE LAN, 1x GigE Internet Ethernet Jacks) BTN: Reset and WPS USB: USB3.0, single port on rear with LED SERIAL: Serial pads internal (unpopulated) LED: Four status lights on top + USB LED WIFI1: 2x2:2 QCA4019 2.4 GHz radio on ch. 1-14 WIFI2: 2x2:2 QCA4019 5 GHz radio on ch. 36-64 WIFI3: 2x2:2 QCA9888 5 GHz radio on ch. 100-165 Support is based on the already supported EA8300. Key differences: EA8300 has 256MB RAM where MR8300 has 512MB RAM. MR8300 has a revised top panel LED setup.
