TP-Link TL-WR902AC v1 is a pocket-size, dual-band (AC750), successor of
TL-MR3020 (both devices use very similar enclosure, in same size). New
device is based on Qualcomm QCA9531 v2 + QCA9887. FCC ID: TE7WR902AC.
Specification:
- 650/391/216 MHz (CPU/DDR/AHB)
- 1x 10/100 Mbps Ethernet
- 1x USB 2.0 (GPIO-controlled power)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH
- 2T2R 2.4 GHz (QCA9531)
- 1T1R 5 GHz (QCA9887)
- 5x LED (GPIO-controlled), 2x button, 1x 3-pos switch
- UART pads on PCB (TP1 -> TX, TP2 -> RX, TP3 -> GND, TP4 -> 3V3, jumper
resitors are missing on TX/RX lines)
- 1x micro USB (for power only)
Flash instructions:
Use "factory" image under vendor GUI.
Recovery instructions:
This device contains tftp recovery mode inside U-Boot. You can use it to
flash OpenWrt (use "factory" image) or vendor firmware.
1. Configure PC with static IP 192.168.0.66/24 and tftp server.
2. Rename "openwrt-ath79-generic-tplink_tl-wr902ac-v1-squashfs-factory.bin"
to "wr902acv1_un_tp_recovery.bin" and place it in tftp server dir.
3. Connect PC with LAN port, press the reset button, power up the router
and keep button pressed until WPS LED lights up.
4. Router will download file from server, write it to flash and reboot.
MAC Address summary:
- wlan1 (2.4GHz Wi-Fi): Label MAC
- wlan0 (5GHz Wi-Fi): Offset -1 from label
- eth0 (Wired): Offset +1 from label
Root access over serial line in vendor firmware: root/sohoadmin.
Based on support in ar71xx target by: Piotr Dymacz <pepe2k@gmail.com>
Use the candelatech firmware for the QCA Wave-2 firmware.
The Qualcomm firmware used for the IPQ401x chip in OpenWrt in 22.03
is experiencing heavily degraded performance due to excessive
retransmits when using A-MSDU. Disabling VHT modes or switching to the
candelatech firmware circumvents this issue.
Apply the same to other Wave-2 platforms in order to keep consistency
with upstream.
Wave-1 chips do not support mesh modes with the -ct firmware, so keep
using the QCA firmware in their case.

Gone due to
commit 071cf7b20f ("Switch to Lua for target definitions")
Has prior been introduced as untested -> broken in
commit d586720c5c ("ar71xx-generic: add support for Ubiquiti NanoBeam M5")
Was commented out in the former commit.
Re-add mikrotik target
Note that previous images were generic ones and as such no migration
path is provided other than manually flashing the image via config-mode.
- [x] Must be flashable from vendor firmware
- [x] Web interface
- [ ] TFTP (untested, but possible according to OpenWrt wiki)
- [ ] Other: <specify>
- [x] Must support upgrade mechanism
- [x] Must have working sysupgrade
- [x] Must keep/forget configuration (`sysupgrade [-n]`, `firstboot`)
- [x] Gluon profile name matches autoupdater image name
(`lua -e 'print(require("platform_info").get_image_name())'`)
- [x] Reset/WPS/... button must return device into config mode
- [x] Primary MAC address should match address on device label (or packaging)
(https://gluon.readthedocs.io/en/latest/dev/hardware.html#notes)
- When re-adding a device that was supported by an earlier version of Gluon, a
factory reset must be performed before checking the primary MAC address, as
the setting from the old version is not reset otherwise.
- Wired network
- [x] should support all network ports on the device
- [x] must have correct port assignment (WAN/LAN)
- On devices supplied via PoE, there is usually no explicit WAN/LAN labeling on the hardware.
The PoE input should be the WAN port in this case.
- Wireless network (if applicable)
- [x] Association with AP must be possible on all radios
- [x] Association with 802.11s mesh must work on all radios
- [x] AP+mesh mode must work in parallel on all radios
- LED mapping
- Power/system LED
- [x] Lit while the device is on
- [x] Should display config mode blink sequence
(https://gluon.readthedocs.io/en/latest/features/configmode.html)
- Radio LEDs
- [x] Should map to their respective radio
- [x] Should show activity
- Switch port LEDs
- [x] Should map to their respective port (or switch, if only one led present)
- [x] Should show link state and activity
Remove support for the TP-Link WDR4900, as it us currently unable to
load its kernel sure to factory bootloader constraints.
Progress on this topic is tracked in #2491
