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.

    1. [quote]except it supports AC2100 WiFI instead of just AC2100[/quote]

      “AC2100 WiFi” vs “AC2100”? Could you help me understand the difference, please?

      1. The second should read AC1200. Already corrected.

      1. Well, I use them as an APs in my lan with openwrt flashed on it and without access through perimeter microtik, so I think, i should be safe.

  1. It is a pity that it is missing USB. Xiaomi Mi 3G router was the last one with USB 3 and it is well supported by OpenWRT.

  2. It’s all downhill since R3G v1.

    MT7621 with 256MB ram and 128MB storage, has a USB 3.0 port, and supported by openwrt.

    1. Agree, but USB was kicking 5WiFi down, so better keep it disabled…:-] and also, most of the usefull apps on openwrt can fit into 128MB RAM. I’m looking forward to get and crack this one.
