I bought a GL-AR750 home router last year, and was very happy with the flexibility of its OpenWrt operating system.
The base system has enough functionality as a home router: it has a web-based configuration interface; WiFi works out of box without fiddling
On the other hand, the system is extensible that I can install additional packages to add VPN server, file sharing, etc.
When I decide to start hacking, I noticed a problem: the GL-AR750 is now part of my "production" network, and I don't want to change it too much to affect my normal life.
Thus, it's time for a second OpenWrt router!
After some online search and comparison, I chose the Onion Omega2 Pro. The strengths of Onion Omega2 Pro are:
- The CPU is MIPS architecture, allowing me to gain some experience with this unfamiliar architecture.
- It has 8GB eMMC storage, giving me plenty of space to install packages.
- It has LiPo battery port, USB host port, and pin headers with SPI and I2C, leaving possibility of building battery-powered IoT projects.
Shipment arrived two months later.
I plugged it in, and found that the Omega2 Pro runs OnionOS, a customized version of OpenWrt.
Apart from GUI differences, it uses a custom WiFi driver wifi-warp-core that has several flaws.
Most notably, my WiFi SSID is
+ (a plus sign), and the Onion would not connect to it.
