Hi friend.
Both K562 and K562e are dual-band edge ONT that supports gigabit access over both Wi-Fi 6 and Ethernet gigabit network ports.
They are both powerful and support the following:
Embedded AI (eAI) acceleration for value-added services, such as online games, online education, and teleconference
Next-generation Wi-Fi 6 MU-MIMO technology
VR/4K over Wi-Fi
160 MHz channel width
Strong anti-interference capability, wide coverage, and network self-healing
One-click pairing and automatic networking
Ethernet port auto-sensing for LAN or WAN mode
Mesh network (tree type)
Remote management, installation, and maintenance APP management, and user APP management
VS. 
K562 K562e
However, their interfaces are slightly different:
