Astrill VPN Applet Setup on Wi-Fi Router through DD-WRT
Channel: Fuad Oljirra

Time Stamp and Description
This is my instructional video for installing Astrill VPN applet into a Secondary/DD-WRT router(Linksys EA6900), which will be independent from my Primary/Home router(in China). I used a Wi-Fi Repeater to connect the Secondary/DD-WRT router(Linksys EA6900) to the Primary/Home router which established an internet connection on the Secondary/DD-WRT router. 

UPDATE
Under Wireless - Wireless Security page:
• Configure the primary router’s Security Mode (e.g. WPA2-PSK), Algorithm (e.g. CCMP AES), and Shared Key - this must match exactly.
• Don’t make my mistake - do not assume the superset e.g. TKIP+CCMP or WPA2-PSK/WPA-PSK will cover both cases! The issue is with this security mode the connection with the primary Wi-Fi will fail every so often. But with the same configuration as the same security mode as the primary Wi-Fi router, it will rarely fail with the connection.

The router is a Linksys EA6900 V1.1 bought on Taobao, where you can search the title 思科家用无线路由器EA6900 EA6500 e4200梅林75千兆有线DD-WRT TT ( https://item.taobao.com/item.htm?spm=a1z09.2.0.0.48162e8dJmlff0&id=538114643053&_u=s2ra4k9f4b6d ) in China, externally has scratches/worn but internally the PCB/motherboard is refurbished to function as new (they have warranty and guarantee, which I used).

I used the DD WRT build r43028 (https://dd-wrt.com/support/other-down...) Firmware Upgrade which I downloaded from the DD-WRT forum--support--other downloads section. (https://dd-wrt.com/support/other-down...) to flash onto my Linksys EA6900 Router.
