ZBT WE826-E is a dual-SIM version of the ZBT WE826. The router has the
following specifications:
- MT7620A (580 MHz)
- 128MB RAM
- 32MB of flash (SPI NOR)
- 5x 10/100Mbps Ethernet (MT7620A built-in switch)
- 1x microSD slot
- 1x miniPCIe slot (only USB2.0 bus)
- 2x SIM card slots (standard size)
- 1x USB2.0 port
- 1x 2.4GHz wifi (rt2800)
- 10x LEDs (4 GPIO-controlled)
- 1x reset button
The following have been tested and working:
- Ethernet switch
- wifi
- miniPCIe slot
- USB port
- microSD slot
- sysupgrade
- reset button
Installation:
The router ships with an older version of OpenWRT, but with a broken web
user interface. In order to install the image, you need to SSH into the
router and run sysupgrade. The default address of the router is
192.168.1.1, user is root and password admin. Once you are in, run the
following command:
sysupgrade -n -F
openwrt-ramips-mt7620-zbtlink_zbt-we826-e-squashfs-sysupgrade.bin
Recovery:
The router ships with a web-based recovery system. If you need to
recover the router, keep the reset button pressed during boot and access
192.168.1.1 in your browser when your machine obtains an IP address.
Upload the firmware to start the recovery process.
How to swap SIMs:
You control which SIM slot to use by writing 0/1 to
/sys/class/gpio/gpio13/value. In order for the change to take effect,
you can either use AT-commands (AT+CFUN) or power-cycle the modem (write
0/1 to /sys/class/gpio/gpio14/value).

v1->v2:
* Use generic board/model detection, updated the match in 01_leds and
02_network (thanks Petr Štetiar).
* Changed the device/target device in the Makefile to match the
compatible-string in the DTS (thanks Petr Štetiar).
* Use the user-space gpio-switch alternative instead of gpio-export in
the DTS (thanks Petr Štetiar).
* Update name of flash node in DTS to the more generic "flash0" (thanks
Petr Štetiar).
* Fix image size in the Makefile (thanks Petr Štetiar).
* Group the wifi-LED together with other devices (thanks Petr Štetiar).
* Updated commit message.
* While the device can be ordered without a modem, I imagine most
devices will be delivered with a modem. I have therefore enabled support
for QMI and Option, so that most modems can be used out of the box.
