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

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

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.
