- RAM : 256 MiB
- Flash : NAND 128 MiB (ESMT PSU1GA30DT)
- WLAN : MT7905DAN + MT7975DN
- 2.4 GHz : b/g/n/ax, 574 Mbps, MIMO 2x2
- 5 GHz : a/n/ac/ax, 1201 Mbps, MIMO 2x2
- Ethernet : 10/100/1000 Mbps x5 (1x WAN, 4x LAN)
- USB : 1x 3.0
- UART : 3.3V, 115200n8
- Buttons : 1x Reset
1x WPS
- LEDs : 1x Power (green)
1x System (green)
1x WAN (green)
1x WiFi 2.4 GHz (green), controlled by phy
1x WiFi 5 GHz (green), controlled by phy
1x WPS (green)
1x USB (green)
5x ethernet leds (green), controlled by switch
- Power : 12 VDC, 1.5 A
Installation
------------
1. Update the router using stock firmware web interface and OpenWrt
factory.bin image.
Recovery and return to stock
----------------------------
1. Assign your PC a static IP 192.168.1.2 and connect to the router using
the ethernet cable;
2. Power off the router;
3. Press Reset button, power on the router and wait until ethernet led
start blinking;
4. Release the button;
5. Open http://192.168.1.1/ (N6 System Recovery Mode) in your browser;
6. Upload OpenWrt factory.bin (or stock firmware *.bin) image and proceed
with upgrade.
MAC addresses
-------------
+---------+-------------------+
| | MAC example |
+---------+-------------------+
| LAN | dc:xx:xx:49:xx:04 |
| WAN | dc:xx:xx:49:xx:05 |
| WLAN 2g | dc:xx:xx:19:xx:06 |
| WLAN 5g | dc:xx:xx:79:xx:06 |
+---------+-------------------+
The WLAN MAC prototype was found in 'Factory', 0x4
The LAN MAC was found in 'Factory', 0x7ef20
The WAN MAC was found in 'Factory', 0x7ef26
Known issue
-----------
2.4 GHz WLAN doesn't start with mt76 driver.
Probable reason:
Original Netis N6 EEPROM contains wrong MT_EE_WIFI_CONF value (0xd2).
Other routers with the same WLAN hardware (e.g., Routerich AX1800)
have MT_EE_WIFI_CONF = 0x92.
Workaround (already included in this commit):
Extract EEPROM to a file at the boot time using preinit script
'09_prepare_eeprom' and change MT_EE_WIFI_CONF (offset 0x190) value
from 0xd2 to 0x92.
