Xiaomi has launched several affordable WiFi routers over the years. Their latest model is called Xiaomi Redmi AC2100 Router and comes with a dual-core, quad-thread MIPS processor, 128MB storage, WiFi 5 with 6 antennas, and four Gigabit Ethernet ports.

The router is said to come with MiWiFi firmware based on OpenWrt with “deep customization”, and can be managed via its web interface (in Chinese) or MiWiFi Android/iOS app. The firmware is said to support Netease UU game accelerator to deliver a lower latency while gaming.
The hardware features are pretty similar to the company’s earlier Xiaomi Mi Router 4 except it supports AC2100 WiFI instead of just AC1200, comes with extra antennas, more storage, and one more Gigabit Ethernet port. That means Xiaomi Redmi AC2100 router should potentially support OpenWrt, as Mi Router 4 does although it requires flashing the firmware via an SPI programmer.
Xiaomi Redmi AC2100 Router (aka RM2100) is sold for 169 RMB (~$25) in China. Price varies a lot from the usual Chines reseller. I first found it on Banggood for $49.99 shipped, and quickly found out GearBest would sell it for just $45.99, but the best price I’ve found so far is on Aliexpress where it goes for around $35 including shipping.
