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 (full 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-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:
In order to switch which SIM is used, you need to do the following:
- Turn off the modem by running the following command:
echo 0 > /sys/class/gpio/power_mpcie/value
- Write either 0 or 1 to /sys/class/gpio/sim_switch/value. After
boot/reboot, the router will always use SIM 0. You can check which SIM
slot is currently used by reading from the file mentioned in the first
sentence.
- Turn on the modem again by running the following command:
echo 1 > /sys/class/gpio/power_mpcie/value
