Multi-WAN Bonding (a.k.a. Load Balancing) on MiWiFi with Third-Party Firmware

About flashing third-party firmware on the MiWiFi, I've briefly covered it before. Simply put, flashing third-party firmware has a similar feel to jailbreaking an iPhone. Speaking of jailbreaking, of course one must mention the Pangu team's iOS 9 exploit. Friends, have you jailbroken today? In truth, jailbreaking or not is sometimes just a wall apart. This wall, before you cross it, restricts you; after you cross it, it still restricts you. To borrow a few lines from Qian Zhongshu, the people inside the wall want to go out, and those outside the wall have also thought of going in. The fairness of society lies in the fact that whether you are outside or inside the system, you cannot have the upper hand everywhere.

Enough of the chitchat, here's a picture of the effect after multi-WAN. I have a 50M broadband, theoretical download speed should be around 6M. After multi-WAN, using a multi-threaded tool, it can reach up to 10M/s. Of course, this is just at idle time and at peak—it depends on many factors.

Back to the topic, on the Pandora official site, for the Xiaomi router, there are only two stable versions, one from May 9 (r512), and one from June 8 (r1024). If you choose the May 9 version, I suggest referring to the article "http://www.newbandeng.com/thread-19752-1-1.html". If it's the latter, configuration is much simpler.

As users have noted, the R512 version has a bug—after multi-WAN, some sites using HTTPS cannot be accessed. The cited article provides a solution, but the author found it useless after trying, so they reflashed to the r1024 version. To enable multi-WAN, you first need to enable virtual WAN interfaces, but before that, configure the default WAN interface in the system so it can connect via dial-up. The benefit of this is that once you enable virtual WAN interfaces, each interface inherits the original WAN's configuration, saving you the trouble of configuring dial-up for each virtual interface. As shown below:

Select PPPoE protocol, fill in the broadband account and password, save and apply.

Below is the detail of the "Interface" column after enabling virtual WAN interfaces.

After the above configuration, you can check the effect in the "Load Balancing" column. Green means dial-up successful.

At this point, all configuration is complete.
