Doing a simple ping to my device shows this:

64 bytes from 10.0.253.101: icmp_seq=6 ttl=64 time=2.04 ms
Some users even report higher values on older kernels:
64 bytes from 192.168.1.10: seq=0 ttl=64 time=0.612 ms
64 bytes from 192.168.1.10: seq=1 ttl=64 time=2.852 ms
64 bytes from 192.168.1.10: seq=2 ttl=64 time=2.719 ms
64 bytes from 192.168.1.10: seq=3 ttl=64 time=2.741 ms
64 bytes from 192.168.1.10: seq=4 ttl=64 time=2.808 ms
The problem is that the governor is set to Ondemand, which causes
the CPU to clock all the way down to 48MHz in some cases.
Switching to performance governor:
64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=0.528 ms
64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=0.561 ms
64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=0.633 ms
64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=0.526 ms
In theory, using the Performance governor should increase power draw,
but it looks like it really does not matter for this soc.
Using a calibrated precision DC power supply (cpu idle):
Ondemand
24.00V * 0.134A = 3.216 Watts
48.00V * 0.096A = 4.608 Watts
Performance
24.00V * 0.135A = 3.240 Watts
48.00V * 0.096A = 4.608 Watts
Let's simply switch to the Performance governor by default
to fix the general jittery behaviour on devices using this soc.

Enable support for allocating user space page table entries in high memory [1],
for the targets which support this feature. This saves precious low memory
(permanently mapped, the only type of memory directly accessible by the kernel).

ZTE MF286D is a LTE router with four gigabit ethernet ports
and integrated QMI mPCIE modem.
Hardware specification:
- CPU: IPQ4019
- RAM: 256MB
- Flash: NAND 128MB + NOR 2MB
- WLAN1: Qualcomm Atheros QCA4019 2.4GHz 802.11bgn 2x2:2
- WLAN2: Qualcomm Atheros QCA4019 5GHz 802.11anac 2x2:2
- LTE: mPCIe cat 12 card (Modem chipset MDM9250)
- LAN: 4 Gigabit Ports
- USB: 1x USB2.0 (regular port). 1x USB3.0 (mpcie - used by the modem)
- Serial console: X8 connector 115200 8n1
Known issues:
- Many LEDs are driven by the modem. Only internal LEDs and wifi LEDs
are driven by cpu.
- Wifi LED is triggered by phy0tpt only
- No VoIP support
- LAN1/WAN port is configured as WAN
- ZTE gives only one MAC per device. Use +1/+2/+3 increment for WAN
and WLAN0/1
Opening the case:
1. Take of battery lid (no battery support for this model, battery cage
is dummy).
2. Unscrew screw placed behind battery lid.
3. Take off back cover. It attached with multiple plastic clamps.
4. Unscrew four more screws hidden behind back case.
5. Remove front panel from blue chassis. There are more plastic
clamps.
6. Unscrew two boards, which secures the PCB in the chassis.
7. Extract board from blue chassis.
Console connection (X8 connector):
1. Parameters: 115200 8N1
2. Pin description: (from closest pin to X8 descriptor to farthest)
- VCC (3.3V)
- TX
- RX
- GND
Install Instructions:
Serial + initramfs:
1. Place OpenWrt initramfs image for the device on a TFTP in
the server's root. This example uses Server IP: 192.168.1.3
2. Connect serial console (115200,8n1) to X8 connector.
3. Connect TFTP server to RJ-45 port.
4. Stop in u-Boot and run u-Boot commands:
setenv serverip 192.168.1.3
setenv ipaddr 192.168.1.72
set fdt_high 0x85000000
tftp openwrt-ipq40xx-generic-zte_mf286d-initramfs-fit-zImage.itb
bootm $loadaddr
5. Please make backup of original partitions, if you think about revert
to stock.
6. Login via ssh or serial and remove stock partitions:
ubiattach -m 9
ubirmvol /dev/ubi0 -N ubi_rootfs
ubirmvol /dev/ubi0 -N ubi_rootfs_data
7. Install image via "sysupgrade -n".

This board is very similar to the RT-ACRH13/RT-AC58U. It must be flashed
with an intermediary initramfs image, the jffs2 ubi volume deleted, and
then finally a sysupgrade with the final image performed.
