The ZyXEL LTE3301-PLUS is an 4G indoor CPE with 2 external LTE antennas.
Specifications:
- SoC: MediaTek MT7621AT
- RAM: 256 MB
- Flash: 128 MB MB NAND (MX30LF1G18AC)
- WiFi: MediaTek MT7615E
- Switch: 4 LAN ports (Gigabit)
- LTE: Quectel EG506 connected by USB3 to SoC
- SIM: 1 micro-SIM slot
- USB: USB3 port
- Buttons: Reset, WPS
- LEDs: Multicolour power, internet, LTE, signal, Wifi, USB
- Power: 12V, 1.5A
The device is built as an indoor ethernet to LTE bridge or router with
Wifi.
UART Serial:
57600N1
Located on populated 5 pin header J5:
[o] GND
[ ] key - no pin
[o] RX
[o] TX
[o] 3.3V Vcc
MAC assignment:
lan: 98:0d:67:ee:85:54 (base, on the device back)
wlan: 98:0d:67:ee:85:55
Installation from web GUI:
- Log in as "admin" on http://192.168.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root at 192.168.1.1
- format ubi device: ubiformat /dev/mtd4
- attach ubi device: ubiattch -m4
- create rootfs volume: ubimkvol /dev/ubi0 -n0 -N rootfs -s 1MiB
- rootfs_data volume: ubimkvol /dev/ubi0 -n1 -N rootfs_data -s 1MiB
- run sysupgrade with sysupgrade image
For more details about flashing see
commit 2449a632084b ("ramips: mt7621: Add support for ZyXEL NR7101").
I recommend to install an initramfs image on the Kernel2 partition if you
want to permanently use OpenWrt.
