A few days ago, the network was suddenly interrupted. After checking the router, it was found that the long-lasting TP-LINK 941 transformer was dead. Just looking for another transformer to plug it in. However, the router becomes unstable and sometimes it restarts itself. Unbearable on the Jingdong, married a 0 yuan to buy K2 back. (Now Jingdong's website does not advertise 0 yuan to buy, is it the rhythm of the rollover.)
Feixun K2 1200M smart dual-band wireless router WIFI through the wall PSG1218399 yuan Jingdong direct link Appearance Gallery Jingdong Express arrived the next day, the speed is still very fast.
K2's outer packaging is a carton package, with a large K2 LOGO on the front
The side of the tray is printed with Fiji's LOGO
The router's parameters and some router features are printed on the back of the router.
Open the box, white K2 exposed
Take out the accessories inside, is the power supply, a quick installation guide, a joint currency manual
The white router body looks pretty still below the QR code of the management software
On the back is the router's vent
The wall of the router is the K2's indicator
Followed by five network cable interfaces and power interfaces
The overall feel of the router
The Fiji K2's official firmware seems to have a back door. There is a lot of news on Baidu. The first thing to do is to swipe a firmware.
In Ensan, I found a lot of flashing articles, and finally found a fool-style brush "official firmware customization version, integrated breeding" support from all K2 official version of the direct WEB upgrade to a customized version
Open system settings - manual upgrade - select the appropriate custom version
Click Upgrade, Router starts to flash custom firmware
After restarting the brush, the display has been successfully written
Brushed features increase wireless AP, ad filtering, SS and other functions
Brushed custom version used two days to find no MAC filter rules, found the entire setting did not find, decided to brush ASUS try.
The computer connects to the LAN port and automatically obtains the IP address. Hold down the K2 reset button and then turn on the power. Hold down for a few seconds. Then the computer accesses http://192.168.1.1 and enters the breed.
First back up the related Eastern routes
Select the downloaded ASUS firmware to upgrade in the firmware update 
After rebooting, connecting to the router, the old Asus firmware has been brushed. Compared to the original firmware, this still adds a lot of features.
After a few days of continuous use, I feel that the firmware is okay, the ad filtering that comes with it is very easy to use, and the video ads are basically gone.
Advantages: If you do not overturn, 0 yuan to buy cheaper, popular router firmware basically has adapt K2.
Disadvantages: slightly lower hardware configuration, no USB, not worth 399 price.
