Banana Pi BPI-WiFi5 is a low-cost WiFi 5 AC1200 router with four gigabit Ethernet ports powered by a 1.2 GHz Siflower SF19A28 dual-core MIPS SoC coupled with 64MB DDR2 and an 8MB flash.
It’s not the first low-cost router from the company, as the Banana Pi BPI-WiFi6 Mini was introduced this summer for $30 with Triductor TR6560 SoC, and with the Banana Pi BPI-WiFi5, they’ve now introduced a lower-end WiFi 5 router going for just about $16 plus shipping on AliExpress or $29.99 on Amazon.

Banana Pi has not provided an OpenWrt image yet, but still shared some information in the wiki including a GitHub repo for the 1806_SDK which has not been updated in over two years. There you’ll find source code for u-boot, Linux 4.14.90, and OpenWrt 18.06 surely leading some to ask “What year is this?”. But don’t worry as we’re told that “Banana Pi work closely with Siflower to make this product a fully open source wireless routing product”. Considering that the MIPS architecture has gotten very little love in the Linux kernel in recent years, I would not expect the Siflower SF19A28 to be ever well supported by mainline Linux, and there will be a security risk of using this router on your network.
We’re also pointed to the official SiFlower documentation, but it’s in Chinese only and has not been updated for a few years. Needless to say, most people should stay away from this router despite the attractive price.

All of this provides great assurance that bugs will never be fixed at all. So indeed better stay away from this, because if it regularly disconnects, hangs or whatever, you’ll be on your own and will soon regret your $16.
