ASUS RT-AC1750_B1 Merlin Firmware and fancyss Setup

ASUS RT-AC1750_B1 is a quite old router. It was first available in 2016. I got it from the former landlord, and found that it could use Merlin Firmware and install some add-on which makes me bypass GFW as long as my device gets connected to the router. This is very convenient because it frees you from installing different softwares on different platforms. And if the proxy subscribe or something goes wrong, you only have to fix one problem instead of many. However, as it is a very old router, it has some cons, for example, not supporting Wifi7, may heat up when running and so on. But for me it is bearable.

First, access router from your device’s browser. Log into the router and you’ll see the Network Map.

Download RT-AC1750_B1_3.0.0.4_385_20433-g3f7796b.trx to your device.

Then, click Administration in the Advanced Settings column. Click Firmware Upgrade. Click Upload after the Manual firmware upgrade. Choose the file you just downloaded and wait for a while. After the new firmware is installed, log in again.

After logging in again, click the KoolCenter. Install the software shellinabox.

Then access the router’s IP address with port 4200 in the browser, and login with your admin account.

Right click, select paste into browser, and enter the code below.

sed -i 's/\tdetect_package/\t# detect_package/g' /koolshare/scripts/ks_tar_install.sh 

After running this command, go to KoolCenter again. Click 本地安装. And upload fancyss_arm_lite_3.3.3.tar.gz

Wait until it is finally installed.

Then go to the KoolCenter and open the 科学上网 lite. You can subscribe or add node to it, and after turning it on, you can have all your devices connected to this Wi-Fi bypass GFW!

Troubleshooting:

After I installed the add-on, I couldn’t download my subscribe. This error kept showing up:

curl: can’t load library 'libssl.so.1.0.0'

I tried to reboot the router, install other add-on and upgrade the KoolCenter. And it finally disappeared. Hope this will help.
