• 450 Mbps - 3SS 2.4GHz 802.11n (40MHz chan.),

• 1300 Mbps - 3SS 5GHz 802.11ac (80MHz chan.) = AC1750 class

Overview

FCC docs indicate a 4T4R 5G radio, but I'm unsure of actual specifications...

"LWW529-A1-BL REV.015" seems to be silkscreened on the board in the FCC photos. It may be manufactured by CyberTAN.

ramips: add support for Linksys EA7300 v2 This submission relied heavily on the work of Santiago Rodriguez-Papa <contact at rodsan.dev> Specifications: * SoC: MediaTek MT7621A (880 MHz 2c/4t) * RAM: Winbond W632GG6MB-12 (256M DDR3-1600) * Flash: Winbond W29N01HVSINA (128M NAND) * Eth: MediaTek MT7621A (10/100/1000 Mbps x5) * Radio: MT7603E/MT7615N (2.4 GHz & 5 GHz) 4 antennae: 1 internal and 3 non-deatachable * USB: 3.0 (x1) * LEDs: White (x1 logo) Green (x6 eth + wps) Orange (x5, hardware-bound) * Buttons: Reset (x1) WPS (x1) Installation: Flash factory image through GUI. This might fail due to the A/B nature of this device. When flashing, OEM firmware writes over the non-booted partition. If booted from 'A', flashing over 'B' won't work. To get around this, you should flash the OEM image over itself. This will then boot the router from 'B' and allow you to flash OpenWRT without problems. Reverting to factory firmware: Hard-reset the router three times to force it to boot from 'B.' This is where the stock firmware resides. To remove any traces of OpenWRT from your router simply flash the OEM image at this point.

Linksys EA7300 V2 Router. .. Help to Identify 6 pin chip. I need help to ID a 6 pin (probably sot-23-6) chip under different marking... I have purchased a lot of 30 (for parts) Routers of of eBay, 15 of them has a 6 pin chip shorted. Same ship, different marking. 1x=S13 1x=F4W 1x=R2G Its a very small chip, about 1.08mm by 1.90mm. It shows different voltage on different pins on a working unit. Thanks in advance¡

Router repair after a thunderstorm

I repaired such a router after a thunderstorm, replacing the CPU and one DC/DC. I used an analog RT7295D. The circuit is drawn from the board, for selecting analogues of a failed dc/dc converter. The difference between this microcircuit and the original on the board is the operating frequency. Analog 500 kHz, original 1.5 MHz. The router has been working for several years.
