Cudy M3000
Cudy M3000 is a WiFi-6 Mesh system having 1×2.5 Gigabit port + 1×1 Gigabit port. It may be sold in solo, two-pack or three-pack bundle. Sometimes, the selling name includes AX3000 like in “Cudy AX3000 Whole Home Mesh WiFi System M3000”.
- M3000 V1 model is in black color but has already reached EOL.
- M3000 V2 model is in white color and is still available for sale. There are two variants of V2 model, distinguished by the 2.5g PHY chip being used in the WAN port. See more info in Hardware Highlights section.

Distinguishing between Realtek RTL8221B (v1/v2 older) vs Motorcomm YT8821 (v2 newer) variants
- If you have a black color V1 model, then it has Realtek RTL8221B PHY chip.
- If you have a white color V2 model, you can determine the 2.5g PHY chip model based on instructions per commit message
45b51ebof YT8821 variant:
How to know if you have the a router with the YT8821 PHY: - Boot the router into the vendor's firmware. Go to Diagnostic Tools -> System Log. Try searching for "rtl8221b". - If there are some matches, you have the Cudy M3000 router with the Realtek PHY and you should NOT use the device defined in this commit. Instead, you should use the device defined in mt7981b-cudy-m3000-v1.dts. - If there are no matches, try searching for "yt8821". If that matches something, you have the Cudy M3000 with the Motorcomm PHY and you should use this device tree (mt7981b-cudy-m3000-v2-yt8821.dts). - If even the yt8821 string did not match anything, then something is wrong. Rebooting the router might help (the system log would be refreshed).
- Check this OpenWrt Forum thread for more detail on YT8821 variant.
Installation instructions
As of Jan 2026, a new variant of M3000 V2 device was shipped with a different PHY chip (Motorcomm YT8821 2.5GbE) as its WAN port. This new variant is ONLY supported in version 25.12.1 and Main Snapshot branch by incorporating commits to include the kmod-phy-motorcomm driver.
If you own this new variant, you should flash the v2 (yt8821 new variant) image instead. See more info in GitHub PR# 22259 & PR# 22423.
Please add the installation procedure here. For now, check out Supported Since Commit field in the above table for basic flash instructions.
