The hardware design of your ITead Zigbee adapter is almost 100% an issue too, so be sure to read this:
Note! Read all updates as this adapter had issues and has since been replaced with a other adapter.
ITead (of Sonoff fame) has announced that will soon sell an inexpensive Zigbee 3.0 USB dongle based on Silicon Labs EFR32MG21 which is a very powerful MCU with an integrated +20 dBm radio amplifier:
ITead Zigbee 3.0 USB Dongle Model: 9888010100045 (Hardware Revision Version 1.3)

Mine worked ONCE, just once. Then nothing. I suspect my Sonoff Zigbee dongle can’t handle the number of devices I have, or something similar. I tried reconnecting the remote with a new battery even. Something strange I noted: even a feet away from the TRADFRI repeater its connected to, the remote has very low LQI and unknown RSSI.
The MCU chip they use is very powerful so can handle loads of connected devices, but the antenna design and unshielded board they use have huge issues with electromagnetic interference. Again read:
